Cooling Efficiency Considerations:

The outer shell of your JL Audio amplifier is
designed to remove heat from the a mplifier
circuitry. For optimum cooling performance, this
outer shell shou ld be exposed to the largest
possible volume of a ir. Enclosing the ampli fier in
a small, poorly ventilated chamber can lead to
excessive heat build-up and degraded
performa nce. If an instal lation calls for an
enclosure around the amplifier, we recommend
that this enclosure be ventilated with the aid
of a fan. In normal applications, fan-cooling
is not necessary.

Mounting the amplifier upside down is
strongly discouraged.

If mounting the ampli fier under a seat,
make sure t here is at least 1 inch (2.5 cm) of
space above the amplif ier’s outer shell to permit
proper cooling.

Safety Considerations:

Your amplifier needs to be installed in a dr y,
well-ventilated environment and in a manner
which does not i nterfere wit h your vehicle’s safety
equipment (air bags , seat belt systems, ABS brake
systems, etc.). You should also take the time to
securely mount the amplifier so that it does not
come loose in t he event of a collision or a sudden
jolt to the vehicle.

Stupid Mistakes to Avoid

• Check before dril ling any holes in your vehicle

to make sure that you will not be drilling
through a gas tank, brake line, wiring harness or
other vital vehicle system.

• Do not run system wiring outside or underneath

the vehicle. This is an extremely dangerous
practice which can result in se vere damage to
your vehicle and person.

• Protect all system wires from sharp metal

edges and wear by caref ully routing them,
tying them down and using grommets and
loom where appropriate.

• Do not mount t he amplifier in t he engine

compart ment, under the vehicle, on the roof
or in any other area that w ill expose the
amplif ier circuitry to the elements.

PROTEC T YOUR HE ARING!

We value you as a long-term customer. For
that reason, we urge you to practice restraint in
the operation of this product so as not to da mage
your hearing and that of others in your vehicle.
Studies have shown that continuous exposure to
high sound pressure levels can lead to permanent
(irreparable) hearing loss. This a nd all other
high-power amplifiers are capable of producing
such high sound pressure levels when connected

to a speaker system. Please li mit your continuous

exposure to high volume levels.

While d riving, operate your audio system in
a manner that stil l allows you to hear necessary
noises to operate your vehicle safely (horns,
sirens, etc.).

SERIAL NUMBER

In the event that your amplifier requires
service or is ever stolen, you will need to have

a record of the product’s seria l number. Please

take the time to enter t hat number in the space
provided below. The serial number can be fou nd
on the bottom panel of the amplifier and on the
amplifier packaging.

POWER CONNECTIONS

Before installi ng the amplifier, disconnect t he
negative (ground) wire f rom the vehicle’s battery.
This will prevent accidental d amage to the system,
the vehicle a nd your body during installation.

The XD1000/1v2’s “+12 V DC” and
“Ground” connections a re designed to

accept 4 AWG power wire. 4 AWG is the
required wire size for this amplifier.

If you are instal ling the XD1000/1v2 with

other amplifiers a nd wish to use a single ma in

power wire, use 2 AWG or 1/0 AWG main power

wire (dependi ng on the overall current demands
of all the amplif iers in the system). This 2 AWG

or 1/0 AWG power wire should terminate into

a fused distribution block mounted as close
to the amplifiers as possible (within 12 inches

/ 30cm of w ire length). The fused output of

the dist ribution block will connect to t he

XD1000/1v2 with 4 AWG power wire. JL Audio

ECS fused distribution block s are recommended

(XD-FDBU-2 and XD-FDBU-4)

Note: Smaller AWG numbers mean bigger wire

and vice-versa (1/0 AWG is the la rgest, 2 AWG is

smaller, then 4 AWG, then 8 AWG, etc.).

To connect the power wires to the amplifier,
first back out the set screw on the top of the
termina l block, using the supplied 2.5 mm hex
wrench. Strip 1/2 inch (12 mm) of insulation from
the end of each w ire and insert the bare wire i nto
the terminal block, seating it firm ly so that no
bare wire is exposed. Whi le holding the wire in
place, tig hten the set screw firmly, tak ing care not
to strip the head of the screw.

The ground connection should be made
using 4 AWG wire and should be kept as
short as possible, while accessing a solid
piece of sheet metal in the vehicle. The
surface of the sheet metal should be sanded
at the contact point to create a clean, meta l­to-metal connection between the chassis
and the termination of the ground w ire.
For optimal groundi ng, we recommend the
use of a JL Audio ECS master ground lug
(XB-MGLU). Alternatively, a sheet metal
screw or bolt can be used with a star washer.

Any wires run through metal barr iers (such
as firewalls), must be protected with a high
qualit y rubber grommet to prevent damage to the
insulat ion of the wire. Failure to do so may result
in a dangerou s short circuit.

Many vehicles employ small (10 AWG -
6 AWG) wire to grou nd the battery to the
vehicle chassis and to connect the alternator’s
positive connection to the battery. To prevent
voltage drops, t hese wires should be upg raded
to 4 AWG when installing amplifier systems
with mai n fuse ratings above 60A.

FUSE REQUIREMENTS

It is absolutely vital that the main power
wire(s) to the amplifier(s) in the system be
fused w ithin 18 inches (45 cm) of the positive
battery post connection. The f use value at each
power wire shou ld be high enough for all of the
equipment being run from t hat power wire. If

only the X D1000/1v2 is being r un from that
power wire, use a 80A f use.

If fusing the amplifier nea r its power
connections (when more than one a mp is being

run from the mai n power wire), use an 80A fuse

(MAXI™ big plastic-body fuse is recommended).

PRODUCT DESCRIPTION

The XD1000/1v2 is a monoblock

amplif ier utilizing JL Audio Nex D™ high

speed switching technology to deliver
outstanding fidelity and efficiency.

The XD1000/1v2 can be operated with a w ide

variet y of source units and system configurations.

Its frequency response is l imited to the range

below 500 Hz. It is not designed for dr iving

midrange speakers or tweeters. Every aspect of its
operation has been optimized for low-frequency
amplif ication. For detailed specif ications, please
refer to Appendi x C (page 13).

TYPICAL INSTALLATION SEQUENCE

The followi ng represents the sequence
for a typical ampli fier installation, using an
aftermarket sou rce unit or OEM Interface
processor (like the CleanSweep CL441dsp).
Additional steps and different procedures may
be required in some applications. If you have
any questions, please contact your authorized
JL Audio dealer for assista nce.

1) Disconnect the negative battery post

connection and secu re the disconnected cable
to prevent accidental reconnection during
installation. This step is not optional.

2) Run 4 AWG power wire from the battery

location to the amplif ier mounting location,
taki ng care to route it in such a way that it will
not be damaged and will not interfere with
vehicle operat ion. Use 2 AWG or larger power
wire and a f used power distribut ion block if
additiona l amplifiers are being installed w ith

the XD1000/1v2.

3) Connec t power wire to the positive battery

post. Fuse the wire w ith an appropriate fuse
block (and connectors) within 18 inches (45
cm) wire length of the positive battery post.

This fus e is essential to protect t he vehicle.
Do not insta ll the fuse until t he power wire
has been sec urely connected to the a mplifier.

4) Run signal cables and remote turn-on w ire

from the source unit to t he final amplifier
mounting location.

5) Run speaker cables from the spea ker systems

to the amplifier mounting location.

6) Find a good, solid metal grou nding point

close to the a mplifier and connec t the
negative power wire to it using appropriate
hardware (use of t he JL Audio ECS master
ground lug, XB-MGLU is recommended).
Use 4 AWG wire, no longer than 36 i nches

(90 cm) from the a mplifier to the ground

connection point. In some vehicles, it may be
necessary to upgrade the battery grou nd wire.
(See page 5 for important notice).

7) Securely mount the amplif ier.

8) Con nect the positive and negative power

wires to t he amplifier. A fuse near the

amplif ier is not necessar y if the XD1000/1v2

is the only device bei ng run from the fused
main power wire. If the fused main power

wire is shared by the XD1000/1v2 and other

amplif iers or devices, fuse each amplifier/

device w ithin 12 inches (30 cm) of wire

length, v ia a fused distribution block
or multiple individual fuse blocks/
on-board f uses.

9) Connec t the remote turn-on wi re

to the ampl ifier or config ure the “Turn-On
Mode” switch for automatic turn-on.

10) Connec t the input cables to the amplifier.

11) Con nect the speaker cables to the amplifier.

12) Caref ully review the amplif ier’s control

settings to make su re that they are set
according to the needs of t he system.

13) Install the power wire fuse (80A for a

single X D1000/1v2) and reconnec t the

negative battery post termina l. Install the fuse

(80A) near the amplifier (if applicable).

14) Turn on the sou rce unit at a low level

to double-check that the a mplifier is
config ured correctly. Resist t he temptation
to crank it up until you have verified the
control settings.

15) Make necessary adjustments to the input

sensitivity controls to obtain t he right
overall out put and the desired balance
in the system. See Appendix A (page 12)
for the recommended input sensit ivity
setting method.

16) Enjoy the fruits of your labor with your

favorite music.

ENGLISH

In signal and DC sensing applications, the

am plif ier’s “Remote” turn-on term inal becomes
a remote turn-on output. This allows the

XD1000/1v2 to turn on other amplifiers in the

audio system that do not have signal sensi ng.

INPUT SECTION

The XD1000/1v2 employs a d ifferential-

balanced input topolog y that provides the user
with a high degree of i nput flexibilit y, while
retaining superior noise reject ion. This type of

circuit also allows the XD1000/1v2 to accept high-

voltage inputs f rom factory source unit outputs
without excessive distortion or noise problems.

You may run a stereo or a mono signal into
the inputs of t he amplifier. The amplifier’s input
section automatical ly sums stereo signals to mono
for the internal ampli fier section. The a mplifier
will operate wit h only one input connection
but will require an increase i n input sensitivity
to overcome the loss of signal. If a mono input
signal is to be run, we recommend that you use

a “Y-adaptor” to split t he mono signal into both

inputs of the a mplifier. If you are feedi ng only

one input and using either the DC- Offset or
Signal S ensing “Turn-On Mode,” you must u se

the left-channel input for t he automatic turn-on
to operate.

Input Voltage Range:

Input Voltage Range: A wide range of sig nal

input voltages can be accom modated by the

XD1000/1v2’s input section (200mV – 8V).

This wide range is spl it up into two sub-ranges,

accessible via the “Input Voltage” switch :

“Low”: for preamp level signals
“High”: for speaker level signals

The “Low ” position on the “Input Voltage”

switch selects an input sensitiv ity range between

200mV and 2V. This means that the “Input Sens.”

rotary control will operate w ithin that voltage
window. If you are using an afterma rket source
unit, with conventiona l preamp level outputs, this
is the position you should select.

The “High” position on t he “Input Voltage”

switch selects an input sensitiv ity range between

800mV and 8V. This is useful for certain high-

output preamp level signals as well as speaker
level output from source units and small
amplif iers. To use speaker level sources, splice t he
speaker out put wires of the source unit or smal l
amplif ier onto a pair of RCA cables or plugs,
or use the JL Aud io ECS Speaker Wire to RCA

adaptor (XD-CLRAIC2-SW).

Line Output C onverters are usual ly not needed

with t he XD1000/1v2. If you find t hat the output

cannot be reduced sufficiently with a direct
speaker level signal applied to the amplif ier and

the “Input Voltage” switch in its “High” position,

you may use a Line Output Converter or voltage
divider to reduce the signal level.

TURNON OPTIONS

The XD1000/1v2 can be switched on and of f

using one of th ree methods, determ ined by the

position of t he amplifier’s “Turn-On Mode”
switch. Ple ase read these option s and decide

which is best suited for your specif ic system.

1) +12V remote turn-on lead (preferred)

2) Signal-sensing turn-on circuit

3) DC offset-sensing tur n-on circuit

+12 V Remote Turn-On : This is the preferred

method for tu rning the amplifier on/off. T he
amplif ier will turn on when +12 V is present at

its “Remote” input and turn off when +12 V is

switched of f. This +12 V remote turn-on signa l is
typically controlled by a source unit's remote

turn-on wire. The XD1000/1v2’s “Remote” turn­on connector will accept 18 AWG – 12 AWG

wire. To connect t he remote turn-on wire to
the ampli fier, first back out the set screw on the
top of the terminal block, using t he supplied 2.5
mm hex wrench. Strip 1/2 inch (12mm) of wire
and inser t the bare wire into the terminal block,
seating it f irmly so that no bare wire is ex posed.
While holding the w ire in the terminal, tighten
the set screw firmly, taki ng care not to strip the
head of the screw and mak ing sure that the wire
is firmly gripped by the set screw.

If a source un it does not have a dedicated
remote turn-on output, consider one of t he
following a lternative turn-on options:

These methods are useful when a conventional
+12 V remote turn-on signal is not available in a
system. These allow you to operate the amplif ier
without hav ing to locate a remote turn-on lead at
the source u nit, which can be ver y useful when
interfacing the amplifier with OEM (factory)
audio systems that do not use conventional +12 V
turn-on leads.

Depending on the cha racteristics of the audio

signal, one of the following methods may work

better t han the other. We recommend trying DC

Offset-Sensing first as it does not require a long
delay to turn the system off af ter the signal is
shut off.

DC Offset-Sensing: The a mplifier will turn on
and off by detecting the presence of a very smal l

DC signa l (of fset) that is typical in the audio

output of most OEM (factory) source units and
amplif iers. The amplifier will turn on and off in

reaction to the presence or absence of t his DC

Offset. The sensitivity of t his circuit is desig ned
for high-level (spea ker level) signals, not for low­level (preamp level) signals. The circuit senses t he
left-channel signa l only.

Signal-Sensi ng: The amplifier w ill turn on and
off by detecting the presence of a fu ll-range
audio signa l at its left-channel input. After

approximately 30 seconds, the amplifier will shut

off. The sensitivit y of this circuit is designed for
high-level (spea ker level) signals, not for low-level
(preamp level) signals. The circuit is tuned to
react to signals at mid-range frequencies. This
prevents false switching from sig nals created by
moving loudspeakers that are in paral lel with the
amplif ier’s input signal.

ENGLISH

Note: The above hint is not “set-in-stone”…
You should always listen to the system caref ully to
determine the best choice as vehicle acoustics and
other factors play a big role in choosing the most
appropriate filter slope.

3) Precise Frequency Selection: The filter

frequency markings on the front pa nel of
the ampli fier are for reference purposes and
are generally accurate to within 1/3 octave
or better. If you would like to select the f ilter
frequency w ith a higher level of precision,
consult Appendix B (page 13) of this manua l.
This cha rt gives you a more accurate frequency
for each of the forty detented positions of the
frequency selection control. This method can
be very useful if the amplifier is mounted in
a location where you can’t see the f ront panel
markings easily.

4) Defeating the LP Filter: The Low-Pass filter

can also be defeated completely, by switching

the “LP Filter Mode/Slope” switch to the
“Off” position. This is usef ul if you are using

an external act ive crossover in the system.
With the internal crossover turned off, the

XD1000/1v2’s upper frequency response l imit is
500 Hz, due to its subwoofer-specific design.

INFRASONIC FILTER

The “Infrasonic Fi lter” is a 24 dB/octave high-

pass filter, with a fixed cutoff frequency of 30 Hz.

This filter is designed to conserve amplifier power
and protect subwoofer systems, without aud ibly
degrading the sub-bass output.

With ported enclosures, the use of t he

“Infras onic Filter” is high ly recommended to

protect the speaker(s) from excessive excursion
below box tuning.

With sealed enclosures, the use of the filter
is less necessary, but can stil l help protect the
speaker system from excessive excursion.

The “Infrasonic Fi lter” can be completely
defeated by selecting the “Off ” position on its

switch. This bypasses all signa l from flowing
through the circuit.

REMOTE LEVEL CONTROL OPTIONAL

With the add ition of the optional Remote

Level Cont rol (HD-RLC), you can control the

subwoofer volume from the front of the vehicle

The HD-RLC connects to the jack labeled
“Remote Level Cont rol” on the Connection
Panel of the amplifier usi ng a standard telephone
cable (supplied with the HD-RLC). If desired,
multiple X D (a nd HD) amplifiers can be
controlled from a single HD-R LC controller

using a single-line, four-wire phone li ne splitter
and multiple phone cables.

When connected to the a mplifier, the

HD-RLC operates as follows: At f ull counter-

clockwise rotation, the audio will mute
completely. At full clockw ise rotation the level

will be the same as if the HD-RLC was not

connected at all. In other words, it operates
strict ly as a level attenuator.

INPUT SENSITIVITY CONTROLS

The control labeled “Input Sens.” can be u sed

to match the sou rce unit’s output voltage to the
input stage of the X D1000/1v2 for ma ximum

clean output. Rotating the control clockwise wil l
result in higher sensitivity (louder for a given
input voltage). Rotating the control counter­clockwise will result i n lower sensitivity (quieter
for a given input voltage).

To properly set the ampli fier for maximum
clean output , please refer to Appendix A (page

12

) in this manual. After using this procedure,

you can then adjust the “Input Sens.” levels

downward if t his is required to achieve the
desired system balance.
Do not increas e any “Input Sens.” setting for

any channel(s) of any amplifier i n the system
beyond the ma ximum level establis hed during
the procedu re outlined in Appendix A (page 12).
Doing so wi ll result in audible distortion and
possible spea ker damage.

FILTER CONTROLS

Most speakers are not designed to reproduce
the full range of f requencies audible by the human
ear. For this reason, most speaker systems are
comprised of multiple spea kers, each dedicated
to reproducing a specific frequency range. Filters
are used to select which frequency range is sent
to each section of a speaker system. The division
of frequency ranges to different speakers ca n be
done with passive filters (coils and /or capacitors
between t he amplifier outputs a nd the speakers),
which are acceptable and commonly used
for filtering between mid-range speakers and
tweeters. Filtering between subwoofer systems

and satellite speaker systems is best done with
active filters, which cut off frequency content at
the input to the amplif ier. Active filters are more
stable than passive f ilters and do not introduce
extra neous resistance, which can degrade
subwoofer performance.

The active low-pass filter built into the

XD1000/1v2 is designed to at tenuate frequencies

above its fi lter frequency, so that the system’s
subwoofers do not reproduce any audible
midra nge content.

This ser ves to improve tonal balance
and to avoid distortion. Correct use
of the fi lter can substantially improve
the fidelity of your aud io system.

2) LP Filter Ope ration: The low-pass filter in the

XD1000/1v2 is ful ly variable between 50 Hz
and 500 Hz v ia the “Filter Freq.” control k nob
(80 Hz is a good starting point for tuning most

systems). The filter also features the ability to

select bet ween a moderate “12dB” per oc tave
or a steep “24dB” per oc tave slope via the “LP
Filter Mode/Slope” switch.
Depending on the subwoofer system and

the vehicle, different slopes may be requ ired
to produce a smooth transit ion to the mid­bass spea kers in the system. E xperiment to
find the slope which best matches t he acoustic
requirements of your system .

Tuning Hint: A trunk mounted sub whose

output has to “ fight” throu gh a rear deck or a

backseat of ten benefits from the 12 dB/octave
slope which lets more upper bass content pass
through. A sub that f ires directly into the
listeni ng environment is more likely to benefit
from a 24 dB/octave slope.

STATUS LED / PROTECTION CIRCUITRY

There is a single multi-color LED on the top

surface of the ampli fier to indicate the a mplifier’s
operating status.

1) Flashing Green: amplifier is powering up,
audio output is muted.

2) Constant Green: amplif ier is on and
functioning normally, audio output is active.

3) Constant Red: lights to indicate that the
amplif ier has exceeded its safe operating
temperature, putting the amplifier into a
self-protection mode, which reduces the
peak power output of the amplifier without
muting the aud io. When its temperature returns
to a safe level, t he red light will ret urn to green
and the amplifier will return to f ull power
operating mode.

4) Constant Amber (Yellow): Indicates
that an over-current condition has occurred and
is accompanied by a muting of t he amplifier’s
output. Because the muting behavior may be
very short in duration, it may manifest itself as
an audible, repetitive ticking or thumping noise
in the output. Over-current conditions can be
caused by a speaker impedance lower t han the
optimum load impedance range for the amplif ier
or a short-circuit in the speaker wiring. The
latter can result from a short circuit between the
positive and negative speaker wires or between
either spea ker wire and the vehicle chassis.

The “Status LED” w ill remain amber for a few

seconds, even if the over-current condition is of a
very short duration.

5) LED off / Amplifier Shuts Off Unexpectedly

The only condition that will shut down

an unda maged XD1000/1v2 completely is i f

battery voltage or remote turn-on voltage drops

below 10 volts. The “Status LED” wil l turn off.

when this occurs. The amplifier wi ll turn back
on when voltage climbs back above 11 volts.
If this is happening in your system, have your
charging system and power wiring inspected.

For more information on troubleshooting this

amplifier, refer to Appendix D (pages 14, 15).

SERVICING YOUR JL AUDIO AMPLIFIER

If your amplifier fa ils or malfunc tions, please
return it to your authorized JL Audio dealer so
that it may be sent in to JL Audio for ser vice.
There are no user serviceable par ts or fuses inside
the ampli fier. The unique nature of t he circuitry
in the JL Audio amplif iers requires specifically

trained serv ice personnel. Do not attempt

to service the amplifier you rself or through
unauthorized repair facilities. T his will not only
void the warranty, but may resu lt in the creation
of more problems within the a mplifier.

If you have any questions about the insta llation or
setup of the a mplifier that have not been covered
in this manual, please contact your dealer or
technica l support.

PREOUTS

The XD1000/1v2 incor porates a buffered, pass-

through preamp output section, so t hat additional
amplif iers can be easily added to the system.
The preamp output delivers the same signal that

is connected to the X D1000/1v2’s inputs.

The preamp output signal is not affected by

the amplifier’s LP Filter (if the input signal is ful l-

range, the preamp output w ill be full-ra nge).

If you plan to use t he “Preouts” to feed
a stereo amplifier, you must connect a
stereo signa l to the input of the amplifier.
A mono signal i nto the ampli fier will result
in a mono signa l out of the preamp output.

SUBWOOFER OUTPUTS

The XD1000/1v2 is designed to deliver power

into subwoofer loads equal to or greater tha n 2
ohms of nominal impedance.

The XD1000/1v2’s subwoofer output s are

designed to accept 16 AWG - 8 AWG wire. To
connect the subwoofer wires to the amplifier,
first back out the set screws on the top of t he
termina l block, using the supplied 2.5 mm hex
wrench. Strip 1/2 inch (12 mm) of insulation
from the end of each wire and insert the bare
wire into t he terminal block, seating it f irmly
so that no bare wire is ex posed. While holding
the wire i n place, tighten the set screw fi rmly,
taki ng care not to strip the head of the screw.

You will notic e that there are t wo “+” positive

connections and t wo “–” negative connections.

This is to facilitate multiple subwoofer wiring.

The two positive and two negative connections
are connected in parallel inside the amplifier.
They are not stereo outputs. Connecting two

subwoofers, each to one set of positive and
negative terminals, wil l result in a parallel
subwoofer connection. When only connecting
one pair of subwoofer wires, it is not necessar y to
use both sets of connections.

Subwoofer loads below 2 ohms nominal are not
recommended a nd may cause the amplifier
to initiate a protection mode, which reduces
power output.

APPENDIX A:
Input Sensitivity Level Setting

Following the directions below w ill allow the
installer to adjust t he input sensitivity of each
amplif ier channel pair simply and easily in just a
few minutes using equipment which is common ly
available in installation bays.

Necessary Equipment

• Digital AC Voltmeter

• CD with a sine-wave test tone recorded at

0 dB reference le vel in the frequency range

to be amplified for that set of channels

(50 Hz for subwoofer channels, 1 kHz for a
midrange application). Do not use attenuated
test tones (-10 dB, -20 dB, etc.).

The Nine-Step Procedure

1) Disconnect t he speaker(s) from the

amplif ier’s speaker out put connectors.

2) Turn off all processing (bass/treble, loudness,

EQ, etc.) on the source unit, processors (if
used) and amplifier. Set fader control to center
position and subwoofer level control to 3/4 of

maxi mum (if used to feed the X D1000/1v2).

3) Turn the amplifier’s “Input Sens.” control all

the way down.

4) Set the source unit volume to 3/4 of full

volume. This will allow for reasonable gain
overlap with moderate clipping at full volume.

5) Using t he chart on this pa ge, determine the ta rget

voltage for input sen sitivity adjust ment according
to the nomin al impedance of t he speaker system
connecte d to the amplifier out puts.

6) Verify that you have disconnected the speakers

before proceed ing. Play a track with an

appropriate sine wave (within t he frequency

range to be amplif ied by the XD1000/1v2) at

3/4 source unit volume.

7) Connect the AC voltmeter to t he speaker output

connectors of t he amplifier. Make sure you test

the voltage at t he correct connectors (+ and –).

8) Increase the “Input Sens.” control until the

target voltage is obser ved with the voltmeter.

9) Once you have adjusted the X D100 0/1v2 to

its maximum low-distortion output level,
reconnect the speaker(s). The “Input Sens.”
controls can now be adjusted downward if the
amplif ier requires attenuation to achieve the
desired system balance.

Do not increase any “Input Sens.” setting for
any amplif ier channel or channe l pair in the
system beyond t he maximum level established
during this procedure. Doing so will resu lt in
audible distor tion and possible speaker damage.

It will be necessary to re-adjust the

“Input Sens.” if any equalizer boost is activated
after setti ng the “Input Sens.” with this

procedure. This applies to any EQ boost circuit,
including source unit tone controls or EQ
circuits. EQ cuts will not requ ire re-adjustment.

ENGLISH

“My amplif ier shuts off once in a wh ile, usually at higher vo lumes.”

Check your voltage source and grounding point. The power supply

of the XD1000/1v2 will oper ate with chargi ng system
voltages down to 10V. Shutdown problems at higher volume

levels can occur when the charg ing system voltage (or remote

turn-on voltage) drops below 10V. These dips c an be of very

short durat ion making them ex tremely difficult to detec t

with a common DC voltme ter. To ensure proper voltage,

inspect all wiring and termination points. It may also be
necessary to upgrade the ground wire connecting the battery
to the vehicle’s chassis and the power wire connecting the

alter nator to the batter y. Many vehicles employ smal l (10

AWG - 6 AWG) wire to grou nd the battery to the vehicle’s
chassis a nd to connect the alter nator to the battery. To prevent
voltage drops , these wires should be upgraded to 4 AWG
when installi ng amplifier systems with m ain fuse ratings

above 60A. Grounding problems are the leading cause of
misdia gnosed amplifier “failures.”

“My amplif ier turns on, but ther e is no output.”

Check the input signa l using an AC voltmeter to measure the

voltage from t he source unit while an appropriate test tone is
played through the source unit (disconnect the input cables
from the amplifier prior to this test). The frequency used
should be in t he range that is to be amplified by t he amplifier

(example: 50 Hz for a sub bass application or 1 kHz for a f ull

range / hig h-pass applic ation). A steady, suff icient voltage

(between 0.1 and 4.0 -volts) should be pres ent at the output of

the signa l cables.

Check the output of the amplifier. Using the procedure explained in

the previous check item (after plugging the input cables back
into the ampl ifier) test for output at the speaker outputs of
the ampli fier. Unless you enjoy test tones at hig h levels, it is
a good idea to remove the speaker wires from the amplifier
while doing this. Turn the volume up approxi mately
halfway. 5 volt AC or more should be measured at the
speaker out puts. This output level can vary greatly between
amplif iers but it should not be in the mi llivolt range with
the source u nit at half volume. If you are reading sufficient
voltage, check your spea ker connections as explained below.

Check to ensure that the spea ker wires are mak ing a good

connection with the metal inside the ter minal block. The
speaker w ire connectors are designed to accept up to 8 AWG
wire. Ma ke sure to strip the wi re to allow for a sufficient
connection with the metal inside the ter minal block.

“How do I prop erly set the input sens itivity on my amplif ier?”

Please refer to Appendix A (page 12) to set t he input sensitivity for

maximum, low-distortion output.

“My amplif ier doesn’t turn on.”

Check the fuse, not just visually, but wit h a continuity meter. It is

possible for a fu se to have poor internal connections t hat
cannot be fou nd by visual inspection. It is best to take t he
fuse out of the holder for testing. If no problem is fou nd with
the fuse, inspect the fu se holder.

Check the integrity of the con nections made to each of the

“+12V DC,” “Ground ,” and “Remote” terminals. Ensure
that no wire insulation is pinched by the terminal set screw
and that each connect ion is tight.

Check to make sure there is +12V at the “Remote” connection of the

amplif ier. In some cases, the t urn-on lead from the sou rce unit
is insuf ficient to turn on multiple devic es and the use of a relay
is required. To test for this problem, jump the “+12V DC ” wire
to the “Remote” termina l to see if the ampli fier turns on.

“I hear a repetitive ticking or popping sound coming out of the speaker(s).”

Check the speaker wires for a possible short, either bet ween the

positive and negative leads or between either spea ker lead
and the vehicle’s chassis ground. If a shor t is present, you will
experience distorted and/or attenuated output. T he “Status
LED” will tu rn amber in this sit uation. It may be helpful to
disconnect the speaker wi res from the amplif ier and use a
different set of wires connected to a test spea ker.

Check the nominal load impedance to verify that the ampli fier is

drivi ng a load equal to or greater t han 2 ohms.

“My amplif ier’s output fluc tuates when I tap on it or hi t a bump.”

Check the connect ions to the amplifier. Ma ke sure that the

insulat ion for all wires has been stripped back far enough to
allow for a good contact area inside the termina l block.

Check the input connectors to ensure that they all are making good

contact wit h the input jacks on the amplifier.

ESPAÑOL

Consideraciones relativas a la eficiencia de
enfriamiento:

La carca sa externa de su amplificador JL Audio

se ha diseñado para eliminar el calor del circuito

del amplificador. Para logra r el rendimiento

de enfriamiento óptimo, la carcasa debe estar
expuesta al mayor volumen de a ire posible.
Si el amplif icador se coloca en una cá mara
pequeña con escasa venti lación, se producirá una
acumulación de calor excesiva y se degradará
el rendimiento. Si la insta lación requiere un
espacio envuelto alrededor del amplificador,
recomendamos que este se ventile con la ayuda de

un ventil ador. Para aplicaciones normales, no se

requiere enf riamiento con un ventilador.

Se desal ienta firmemente montar el
amplificador boca abajo.

Si se monta el amplificador debajo de
un asiento, asegúrese de que haya por lo
menos 2,5cm (1 pulgada) por encima de la
carcasa del amplificador pa ra permitir un
enfria miento adecuado.

Consideraciones relativas a la seguridad:

El amplificador se debe instalar en un
lugar seco y bien ventilado, y de manera que
no interfiera con los equipos de seguridad
del vehículo (bolsas de aire, sistemas de
cinturones de seguridad, sistemas de frenos

ABS, etc.). Debe dedicar tiempo a montar

el amplif icador de manera segu ra a fin de
que no se suelte si se produce un choque
o el vehículo da un salto repentino.

SECUE NCIA DE INSTALACI ÓN TÍPICA

A continuación se representan los pasos
necesar ios para la instalación típica de
un amplificador mediante el uso de una
unidad f uente posventa o un procesador
de interfaz de fábrica (como el CleanSweep
CL441dsp). En algunos casos, pueden
requerirse pasos adicionales y procedimientos
diferentes. Si tiene alg una duda, póngase
en contacto con u n distribuidor autorizado
de JL Audio para solicita r asistencia.

1) Desconecte la conexión del polo negativo de

la batería y sujete el cable desconectado pa ra
evitar una reconex ión accidental durante la
instalación. Este paso no es opcional.

2) Lleve el cable de alimentación ca libre 25

mm desde la ubicación de la batería hasta
el lugar de montaje del amplif icador, con
cuidado de colocar el cable de manera que no
se dañe o interfiera con el funcionamiento
del vehículo. Si desea instala r amplificadores

adicionales junto con el XD1000/1v2,

use un cable de alimentación calibre
35 mm o más gr ueso y un bloque de
distribución de alimentación con f usibles.

3) Conecte el cable de al imentación al polo

positivo de la batería. Interru mpa el cable con
un bloque de fusibles apropiado (y conectores)
a 45cm (18pulgadas) como máximo del polo
positivo de la batería. Este fusible es esencial

para proteger el vehículo. No instale el
fusible hast a que el cable de alimentación se
haya conectado al amplificador.

4) Lleve los cables de señal y el cable de encendido

remoto desde la unidad fuente hasta el lugar de
montaje final del amplificador.

5) Lleve los cables de los alt avoces desde el

sistema de altavoces hasta el lugar de montaje
del amplif icador.

6) Busque un pu nto de toma a tierra de metal

sólido adecuado cercano al ampli ficador y
conecte el cable de alimentación negativo
a éste usando la tornillería adecuada (se
recomienda el u so de la orejeta de toma a tierra
JLAudioECS, XB-MGLU). Use cable calibre
25 mm, con una long itud menor a 90cm
(36pulgadas) desde el amplificador hasta el
punto de toma a tier ra. En algunos veh ículos,

ESPAÑOL

Encendido remoto de +12 V: Este es el método
preferido para encender y apaga r el amplificador.
El amplificador se encenderá cuando haya
+12 V en la entrada “Remote” (Remoto) y se
apagará cuando se desconecte la a limentación
de +12 V. Esta señal de encendido remoto de
+12 V generalmente es controlada por el cable
de encendido remoto de una unidad fuente. El

conector de enc endido “Remote” del XD1000/1v2

usa cable calibre 1 mm-3mm . Para conectar
el cable de encend ido remoto al amplificador,
primero af loje el tornillo de fijación en la pa rte
de arriba del bloque terminal, usando la llave

hexagonal de 2,5mm provista. Pele 12 mm
(0,5 pulgada) de cable e inserte el cable pelado

en el bloque de term inales, introduciéndolo
firmemente de forma que no haya cable pelado
expuesto. Mientras sostiene el cable en el
termina l, ajuste el tornillo de fijación f irmemente,
con cuidado de no robar la cabeza del tornillo
y asegurándose de que el cable esté f irmemente
agarrado por el torni llo de fijación.

Si la unidad f uente no tiene una salida
dedicada de encendido remoto, c onsidere
una de las sig uientes opciones de encendido
alternativas:

Estos métodos son útiles cuando no hay una
señal de encendido remoto de +12 V convencional
disponible en el sistema. Estos le permiten
operar el amplificador sin tener que ubicar un
cable de encendido remoto en la unidad fuente,
lo cual puede ser muy útil a l interconectar el
amplif icador con sistemas de audio de fábrica
que no usen cables de encendido convencionales
de+12 V.

Según las característ icas de la señal de audio,
uno de los siguientes métodos puede funcionar
mejor que el otro. Recomendamos probar el
modo de detección de corrimiento de CC ya que
no requiere un retardo prolongado para apagar el
sistema luego de que se apaga la seña l.

Detección de cor rimiento de CC: el amplificador
se encenderá y apagará detectando la presencia
de una muy pequeña señal de CC (corrimiento)
que es típica en la salida de audio de la mayoría
de las unid ades fuente y los amplif icadores de
fábrica. E l amplificador se encenderá y apagará
en reacción a la presencia o ausencia de este
corrimiento de CC. La sensibilidad de este
circuito está diseñada para señales de a lto nivel
(nivel de altavoces), no para señales de bajo
nivel (nivel de preamplificación). El circu ito
solo detecta la señal del canal izquierdo.

Detección de señal: El amplificador se
encenderá y apagará detectando la presencia de
una señal de rango completo en la entrada del
canal izquierdo. Luego de aproximadamente

30 segundos, el amplificador se apagará. La

sensibilidad de este circuito está diseñada
para seña les de alto nivel (nivel de altavoces),
no para seña les de bajo nivel (nivel de
preamplif icación). El circuito está ajustado para
reaccionar a señales de f recuencia de rango
medio. Esto impide un falso accionamiento del
interruptor debido a señales generadas por el
movimiento de altavoces que estén en paralelo
con la señal de entrada del a mplificador.

En las aplicaciones de detección de señal y
de CC, el terminal de encendido “Remote”
del amplificador se convierte en u na salida
de encendido remoto. E sto permite que el

XD1000/1v2 encienda ot ros amplificadore s del

sistema de audio que no tengan detección de seña l.

Para conec tar los cables de alimentación al

amplif icador, primero afloje el tornillo de fijación
en la parte superior del bloque terminal, usando

la llave hex agonal de 2,5 mm prov ista. Pele 12
mm (0,5 pulgada) del aislamiento del extremo de

cada cable e i nserte el cable pelado en el bloque de
termina les, introduciéndolo firmemente de forma
que no haya cable pelado expuesto. Mientras
sostiene el cable en su lugar, ajuste el tornil lo de
fijación firmemente, con cuidado de no robar la
cabeza del tornil lo.

Es recomendable que la conexión a tierra
se realice mediante un cable de 25 mm lo
más corto posible, con acceso a una chapa
metálica en el vehícu lo. La superficie de la chapa
metálica debería pulirse en el punto de contacto
para crear una buena conexión entre metales
entre el chasis y la terminación del cable de

toma a tier ra. Para una toma a tierra óptima,

recomendamos el uso de una orejeta maestra de
toma a tierra JL Audio ECS (X B-MGLU). Como
alternativa, se puede usar un tornillo o perno
de chapa metá lica con una arandela en estrella.

Se deben proteger todos los cables que
atraviesen barreras metálicas, como los
cortafuegos, con u n ojal de caucho de alta
calidad a fin de evitar daños al a islamiento del
cable. En caso contrario, podr ía producirse un
cortocircuito peligroso.

En muchos vehícu los, se utilizan cables
pequeños (calibre 5 mm - calibre 15 mm )
para conec tar la batería a tierra en el chasis del
vehículo y pa ra conectar el conector positivo
del alternador a la batería. C on el fin de evitar
caídas de voltaje, el calibre de estos cables se
debe aumentar a c alibre 25 mmmm cuando se
instalan sistemas de a mplificadores con fusible
principal de más de 60 A.

REQUISITOS DEL FUSIBLE

Es fundamental que los cables de a limentación
principales que van a l amplificador o los
amplif icadores del sistema tengan fusibles
conectados a 45 cm (18 pulgadas) como máx imo
de la conexión del polo positivo de la batería. El
valor del fusible en cada cable de alimentación
debe ser suf icientemente alto para todo el
equipo que se a limente con dicho cable. Si solo

se ali menta el XD1000/1v2 con ese cable de
alimentación, use u n fusible de 80 A.

Si se conecta n fusibles al ampli ficador
cerca de sus conexiones de alimentación
(cuando se alimenta más de un amplificador
con el cable de alimentación principa l), use

un fusible de 80A (se recomienda el f usible

MAXI™ de cuerpo plástico grande).

OPCIONES DE ENCENDIDO

El XD1000/1v2 se puede encender y apagar

usando uno de tres métodos, determinados por
la posición del conmutador “ Turn-On Mode” del
amplif icador. Lea estas opciones y elija cuál se
ajusta mejor a su sistema específico.

1) Cable de encendido remoto de +12 V

(pr eferido)

2) Circuito de encend ido detector de señal

3) Circuito de encend ido de corrimiento de CC
