Monoblock Subwoofer Amplifier

Cooling Efficiency Consid erations:

Your JL Audio amplifier employs an
advanced type of heat management, cal led
RealSink™. This feature takes advantage of
convection and radiation effects to remove
heat from the amplifie r circuitry. For opt imum
cooling performance, the vertical heat sinks
located at the back of the amplifier shou ld be
exposed to as large a volume of air as possible.
Enclosing the amplifier in a small, poorly
ventilated chamber can lead to excessive heat
build-up a nd degraded per formance. If a n
insta llation cal ls for an enclosure around the
amplif ier, we recommend that this enclosure
be ventil ated with the aid of a fan. I n normal
applications, fan-cooling is not necessary, but
you sti ll need to follow s ome basic guidel ines:

• Amplifier mounted vertically with heat sink fins

pointing up: Optimum

• Amplifier mounted horizontally,

right side up: Good

• Amplifier mounted horizontally, but upside

down: Fair (not recommended if there is
less than 1 inch (2.5 cm) clearance above the
amplif ier heat sinks)

• Amplifier mounted vertically with heat sink fins

pointing lateral ly: Fair

• Amplifier mounted vertically with heat sink fins

pointing down: Poor (not recommende d)

If mounting the amplifier under a seat,
make su re there is at lea st 1 inch (2.5 c m) of
space above the amplif ier’s outer shel l to permit
proper coolin g.

Safety Considerations:

Your amplifier needs to be installed in a dry,
well-ventila ted environment a nd in a manner
which does not interfere with your vehicle’s safety
equipment (air bags, seat belt systems, ABS brake
systems, etc.). You should also take the time to
securely mount the ampli fier using appropr iate
hardware so that it does not come loose in t he
event of a co llision or a sudden jolt to the vehicle.

Stupid Mistakes to Avoid:

• Check before drilling any holes in your vehicle

to make sure that you will not be drilling
throug h a gas tank , brake line, wiring har ness or
other v ital vehicle sys tem.

• Do not run system wiring outside or underneath

the vehic le. This is a n extremely da ngerous
practice which can result in severe damage to
your vehic le and person.

• Protect all system wires from sharp metal

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

• Do not mount the amplifier in the engine

compart ment, under the ve hicle, on the roof
or in a ny other area th at will exp ose the
amplifier circuitry to the elements.

PROTECT YOUR H EARING!

We value you as a long-term customer. For
that rea son, we urge you to pr actice restra int in
the oper ation of this produc t so as not to d amage
your hearing and that of others in your vehicle.
Studies have shown that cont inuous exposure to
high sound pressure levels can lead to permanent
(irrepara ble) hearing loss . This and a ll other
high-power a mplifiers ar e capable of producing
such hig h sound pressure le vels when connect ed
to a spea ker system. Plea se limit your continuous
exposu re to high volume le vels.

While driving, operate your audio system in
a manner that stil l allows you to he ar necessar y
noises to operate your vehicle safely (horns,
sirens, etc.).

1000 /1v2

Monoblock Subwoofer Amplifier

The 100 0/1's “+1 2 V D C” and “Ground”
connect ions are designed to accept 4 AWG power
wire. 4 AWG is the only recommended power

wire size for this amplifier.

If you are installi ng the 1000/1 wit h other
amplif iers and wish to use a single main power
wire, use 2 AWG or 1/0 AWG main power wire
(depending on the overall current demands of all
the amplifiers in the system). This 2 AWG or
1/0 AWG power wire shoul d terminate into
a distribution block mounted as close to the
amplifiers as possible and should connect to the
1000/1 with 4 AWG power wire.

Note: that smaller AWG numbers mean bigger
wire a nd vice-versa (1/0 AWG is biggest, 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
amplifier, 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 the
receptacle on the front panel of the amplifier,
seating it firmly so that no bare wire is exposed.
While holding the wire in place, tighten the set
screw firmly, taking care not to strip the head
of the sc rew.

The grou nd connection shou ld be made
using 4 AWG wire and should be kept as short
as possible, while accessing a solid piece of sheet
metal i n the vehicle. T he surface of t he sheet
metal s hould be sanded at the contact poi nt to
create a cle an, metal-to-meta l connection be tween
the chassis and the termination of the ground
wire. For optimal grounding, we recommend
the use of a JL Audio ECS master ground
lug (XB -MGLU). Altern atively, a sheet metal
screw or bolt can be used with a star washer.

Any wires run through metal barriers (such as
firewa lls), must be protec ted with a hi gh quality
insulat ing grommet to prevent damage to t he
insulation of the wire. Failure to do so may result
in a dangerous short circuit.

IMPORTANT

!

Many vehicles employ small (10 AWG -
6 AWG) wire to ground the battery to the vehicle
chassis a nd to connect t he alternator’s positive
connection to the battery. To prevent voltage
drops, these wires should be upgraded to 4
AWG (or larger) when installin g a 1000/1v2.

FUSE REQUIREMENTS

It is absolutely vital that the main power
lead to the amplifier(s) in the system be fused
within 18 inches (45 cm) of the positive battery
post connection. The fuse value at each power
wire should be high enough for all of the
equipment being run from that power wire.
If only t he 1000/1v2 is being run from that power
wire, we recommend a 100A AN L fuse be use d.

No fuse is required directly before the
amplif ier power connect ion. If one is desi red,
we recommend the use of a 100A A NL fuse for
each 1000/1v2.

PRODUCT DESCRIPTION

The JL Audio 1000/1v2 is a monoblock

subwoofer amplifier utilizing proprietary and
patented Class D technology. Its frequency
response i s limited to t he range below 250 Hz. It

is not designed for driving midrange speakers or
tweeters. Every aspect of its operation has been
optimized for low-frequency amplification.
For detai led specific ations, please re fer to
Appendix B (page 15).

TYPICAL INSTALLATION SEQUENCE

The following represents the sequence
for a ty pical amplif ier instal lation, using a n
after market source u nit or OEM Interfa ce
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 dea ler for assista nce.

1) Disconnect the negative battery post

connection and secure the disconnected cable
to prevent accidental re-connection during
insta llation. This step is not optional!

2) Run power wire (minimum 4 AWG)

from the battery location to the amplifier
mounting location, taking care to
route it in such a way that it will not be
damage d and will not interfere with
vehicle oper ation. Use 2 AWG or 1/0
AWG power w ire if additiona l amplifiers
are being installed with the 1000/1v2.

3) C onnect power wi re to the positive battery

post. Fuse the wire with an appropriate fuse
block (and con nectors) within 18 inches
(45 cm) wire len gth of the p ositive battery
post. This fuse is essential to protect the

vehicle. Do not install the fuse until the power

wire has been connected to the amplifier.

4) Run signal cables (RCA cables) and remote

turn-on wire from the source unit to the
amplifier mounting location.

5) Run speaker wire from the speaker systems to

the ampl ifier mounti ng location.

6) Find a good, solid metal grounding point

close to t he amplifier and connect t he
negative power wire to it usi ng appropriate
hardware. Use minimum 4 AWG power wire,
no longer than 36 inches (90 cm) from the
amplifier to the ground connection point. In
some vehicles, it may be necessary to upgrade
the bat tery ground w ire. (See page 5 for
importa nt notice).

7) Securely mount the amplifier using

appropriate hardware.

8) Connect the positive and negative power
wires to the amplifier. A fuse near the
amplif ier is not necess ary.

9) C onnect the remote turn-on wire
to the a mplifier.

10) Connect the RCA input cables
to the a mplifier.

11) C onnect the spe aker wires to the amplif ier.

12) Carefully review the amplifier’s control

settings to make sure that they are set
according to the needs of the system.

13) Instal l power wire fuse (100A for a
single 100 0/1v2) and recon nect the negati ve
battery post terminal.

14) Turn on the source un it at a low level
to double-check that the amplifier is
config ured correct ly. Resist t he temptation
to crank it up until you have verified the
control set tings.

15) Ma ke necessar y adjustments to t he input
sensitivity controls to obtain the right
overall output and the de sired balance
in the system. See Appendix A (page 14)
for the recommended input sensitivity
setting method.

16) Enjoy the fruits of your labor with your
favorite music .

The ampl ifier wil l operate with only one input
connection (left or right), but will require an
increase in 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” like the
JL Audio E CS model XB- CLRAICY-1F2M to split
the mono si gnal into bot h inputs of the a mplifier.

2) Input Voltage Ra nge: A wide range of signal

input voltages can be accommodated by

the 1000/1v2’s input section (200mV – 8V).

This w ide range is spl it up into two sub-

ranges, accessible via switches located in the

“Amplifier Input Section” of the amplifier.

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

switch s elects an input sensitivity r ange

between 200mV and 2V. This means that

the “Input Sens.” rotary c ontrol will ope rate

within that voltage window. If you are using

an aftermarket source unit, with conventional

preamp-level outputs, this is most likely the

position t hat you will use. The “High” position

on the “I nput Vo ltage” switch selects an input

sensitivity range between 800mV and 8V. This

is usef ul for certa in high-output pre amp level

signals as well as speaker-level output from

source units and small amplifiers. To use

speaker-level sources, splice the speaker output

wires o f the source un it or small a mplifier

onto a pair of RCA cables or plugs or use the

JL Audio E CS Speaker Wir e to RCA adaptor

(XB-CLRA IC2-SW).

IMPORTANT

!

The output of the amplifier will decrea se
for a given input voltage when the “Input
Range” s witch is placed i n the “High” position.
Conversely, the output will be higher with
the switch in the “Low” position. W hile this
may sound counter-intuitive, it is correct
as described.

3) Input Se nsitivity Adjust ment: Located

next to t he “Input Voltage” switch, in the
“Amplifier Input Section”, is a rotary control
labeled “Input Sens.”. Once the appropriate
“Input Voltage” range has been selected, this

rotar y control can be used to match the source
unit’s output voltage to the input stage of the
amplifier for maximum clean output. Rotating
the contr ol clockwise w ill result in higher
sensitivity (louder for a given input voltage).
Rotating the control counter- clockwise w ill
result in lower sensitivity (quieter for a given
input voltage). To properly set the amplifier
for maximum clean output, please refer to
Appendix A (page 14) in this manual. After
using this procedure, you can then adjust
the level of the amplifier by adjusting the
input sensitivity downward, if the amplifier
requires attenuation to ach ieve the desired

system ba lance. Do not i ncrease the “Input
Sens.” setting for any amplifier in the system

beyond the maximum le vel established du ring
the procedure outlined in Appendix A (page

14). Doing so will result in audible distortion

and poss ible speaker da mage.

REMOTE TURNON

The 1000/1v2 uses a conventional +12V remote
turn-on lead, typically controlled by the source
unit's remote turn-on output. The amplifier will
turn on when +12V is prese nt at its “Remote ”
input and turn off when +12V is switched off. If
a source u nit does not have a dedicated remote
turn-on output, the amplifier’s turn-on lead can
be connec ted to +12V via a switch that derives
power from an ignition-switched circuit.

The 100 0/1's “Remote” t urn-on connector is
designed to accept 12 AWG – 8 AWG wire.
12 AWG is more than adequate for this purpose.
To connect the remote turn-on wire to the
amplif ier, first back out the set screw on the
top of the amplifier, using the supplied hex
wrench. Strip 1/2 inch (12mm) of wire and
insert the bare wire into the receptacle on the
front panel of the amplifier, seating it firmly so
that no bare wire is exposed. Smaller wire than
12 AWG can be use d, but it may be nece ssary
to strip 1 inch of insulation from the wire and
fold the ba re wire in ha lf prior to ins ertion.
While holding the wire in the terminal, tighten
the set screw firm ly, taking ca re not to strip
the head of the screw and making sure that
the wi re is firm ly gripped by t he set screw.

Monoblock Subwoofer Amplifier

AMPLIFIER INPUT SECTION

The 1000/1v2 employs a differential-balanced
input topolog y that provides the user wit h a high
degree of input flexibi lity while retaining sup erior
noise rejec tion. This t ype of circu it also allows
the 1000/1v2 to accept high-voltage inputs from
factory source unit outputs without excessive
distort ion or noise problems.

1) Input Connec tions: A standard left/right pair

of RCA ty pe jacks is u sed for input on
the 1000/1v2. You may run a stereo or a mono
signal into the inputs of the amplifier. The
amplifier’s input section automatically sums
stereo signals to mono for the internal

amplif ier section an d for the “LP” “Filter
Mode” of t he “Preamp Output ” section.

IMPORTANT

!

If you plan to use the “Preamp Output” in
“Full-Range” or “HP” mode to feed a stereo
amplif ier, you must con nect a stereo sig nal to
the input of the amplifier. A mono signal into
the amplifier wil l result in a mono signal out of
the preamp output. (It’s a great amplifier, but it
doesn’t do mag ic).
