PLANNING YOUR INSTALLATION

It is important that you take the time to read
this manual and that you plan out your
installation carefully. The following are some
considerations that you must take into account
when planning your installation.

Cooling Efficiency Considerations:

The outer shell of your JL Audio amplifier is
designed to remove heat from the amplifier
circuitry. For optimum cooling performance, this
outer shell should 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 and degraded
performance. If an installation 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 amplifier
under a seat, make sure there is at least 1 inch
(2.5 cm) of space above the amplifier’s outer
shell to permit proper cooling.

Safety Considerations:

Your amplifier needs to be installed in a dry,
well-ventilated environment and 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 amplifier so that it does not
come loose in the event of a collision 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
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 severe damage to
your vehicle 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

compartment, under the vehicle, on the roof
or in any other area that will expose the
amplifier circuitry to the elements.

PRODUCT DESCRIPTION

The JL Audio XD200/2 is a two-channel,
full-range audio amplifier utilizing JL Audio
NexD™ ultra-high speed switching technology to
deliver outstanding fidelity and efficiency.

The XD200/2 can be operated with a wide
variety of source units and system configurations.

TYPICAL INSTALLATION SEQUENCE

The following represents the sequence
for a typical amplifier installation, using an
aftermarket source unit or OEM Interface
processor (like the CleanSweep CL441dsp).
Additiona l steps and different procedures may
be required in some applications. If you have
any questions, please contact your authorized
JL Audio dealer for assistance.

1) Disconnect the negative battery post

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

2) Run 8 AWG (minimum) power wire from the

battery location to the amplifier mounting
location. Take care to route the wire in such a
way that it will not be damaged and will not
interfere with vehicle operation. Use 4 AWG
or larger power wire and a power distribution
block if additional amplifiers are being
installed with the XD200/2.

3) Connect power wire to the positive battery

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

This fuse is essential to protect the vehicle.
Do not install the fuse until the power wire
has been securely connected to the amplifier.

4) Run signal cables and remote turn-on wire

from the source unit to the final amplifier
mounting location.

5) Run speaker cables from the speaker systems

to the amplifier mounting location.

6) Find a good, solid metal grounding point

close to the amplifier and connect the
negative power wire to it using appropriate
hardware (use of the JL Audio ECS master
ground lug, XB-MGLU is recommended).
Use 8 AWG 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 battery ground
wire. (See page 5 for important notice).

7) Securely mount the amplifier.

8) Connect the positive and negative power

wires to the amplifier. A fuse near
the amplifier is not necessary if the
XD200/2 is the only device being run
from the fused main power wire. If
the fused main power wire is shared
by the XD200/2 and other amplifiers
or devices, fuse each amplif ier/device
within 12 inches (30 cm) of wire length,
via a fused distribution block or multiple
individual fuse blocks/on-board fuses.

9) Connect the remote turn-on wire

to the amplifier.

10) Connect the input cables to the amplifier.

11) Connect the speaker cables to the amplifier.

12) Carefully review the amplifier’s control

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

13) Install the power wire fuse (20A for a

single XD200/2) and reconnect the negative
battery post terminal. Install the fuse (20A)
near the amplifier (if applicable).

14) Turn on the source unit at a low level

to double-check that the amplifier is
configured correctly. Resist the temptation
to crank it up until you have verified the
control settings.

15) Make necessary adjustments to the input

sensitivity controls to obtain the right
overall output and the desired 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.

POWER CONNECTIONS

Before installing the amplifier, disconnect the
negative (ground) wire from the vehicle’s battery.
This will prevent accidental damage to the system,
the vehicle and your body during installation.

The XD200/2’s “+12 V DC” and “Ground”
connections are designed to accept 8-4 AWG
power wire. 8 AWG is the minimum required

wire size for this amplifier.

If you are installing the XD200/2 with other
amplifiers and wish to use a single main power
wire, use 4 AWG, 2 AWG or 1/0 AWG main
power wire (depending on the overall current
demands of all the amplifiers in the system).
This large power wire should terminate into a
fused distribution block mounted as close to
the amplifiers as possible (within 12 inches /
30cm of wire length). The fused output of the
distribution block will connect to the XD200/2
with 8 or 4 AWG power wire. JL Audio ECS
fused distribution blocks are recommended
(XD-FDBU-2 and X D-FDBU-4)

Note: Smaller AWG numbers mean bigger
wire and vice-versa (1/0 AWG is the largest, 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
terminal 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
the terminal block, 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 screw.

The ground connection should be made
using 8 or 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, metal­to-metal connection between the chassis
and the termination of the ground wire.
For optima l grounding, 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 barriers (such
as firewalls), must be protected with a high
quality rubber grommet to prevent damage to the
insulation of the wire. Failure to do so may result
in a dangerous short circuit.

Many vehicles employ small (10 AWG -
6 AWG) wire to ground the battery to the
vehicle chassis and to connect the alternator's
positive connection to the batter y. To prevent
voltage drops, these wires should be upgraded
to 4 AWG when installing amplifier systems
with main 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 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 the X D200/2 is being run from that power
wire, we recommend a 20A fuse be used.

If fusing the amplif ier near its power
connections (when more than one amp is being
run from the main power wire), use a 20A fuse.
MAXI™ plastic-body fuses are recommended.

TURNON LEAD

The XD200/2 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 present at its “Remote”
input and turn off when +12V is switched off. If
a source unit does not have a dedicated remote
turn-on output, the amplifier’s turn-on lead can
be connected to +12V via a switch that derives
power from an ignition-switched circuit.

The XD200/2’s “Remote” turn-on connector
is designed to accept 18 AWG – 12 AWG wire. To
connect the remote turn-on wire to the amplifier,
first back out the set screw on the top of the
terminal block, using the supplied 2.5mm hex
wrench. Strip 1/2 inch (12mm) of wire and insert
the bare wire into the terminal block, seating it
firmly so that no bare wire is exposed. While
holding the wire in the terminal, tighten the set
screw firmly, taking care not to strip the head of
the screw and making sure that the wire (not the
insulation) is firmly gripped by the set screw.

INPUT SECTION

The XD200/2’s input section allows you to
send signals to the amplifier section through
the use of two differential-balanced inputs.

Input connections are via up to one pair of
traditional RCA-type jacks.

Input Voltage Range:

The XD200/2’s input sections are designed to
accept signal voltages from 100mV – 4V. This
will accommodate all preamp level signals and
many speaker level signals.

To use speaker-level sources, simply splice
the speaker output wires of the source unit
onto a pair of RCA plugs. (or use JL Audio part
XD-CLRAIC2-SW) No “line output converter” is
needed in most cases.

If you find that the output cannot be reduced
suff iciently with a direct speaker level signal
applied to the amplifier, you may use a “line
output converter” to reduce the signal level.

6 | JL Audio - XD200/2 Owner’s Manual

INPUT SENSITIVITY CONTROL

The control labeled “Input Sens.” can be used

to match the source unit’s output voltage to the
input stage of the amplifier for maximum clean
output. Rotating the control clockwise will result
in higher sensitivity (louder for a given input
voltage). Rotating the control counter-clockwise
will 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 12) in this manual. After using this
procedure, you can then adjust the “Input
Sens.” level downward if this is required
to achieve the desired system balance.

Do not increase any “Input Sens.” setting for
any channel(s) of any amplifier in the system
beyond the maximum level established during
the procedure outlined in Appendix A (page 12).
Doing so will result in audible distortion and
possible speaker damage.

FILTER CONTROLS

Most speakers are not designed to reproduce
the full range of frequencies audible by the human
ear. For this reason, most speaker systems are
comprised of multiple speakers, 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 can be
done with passive filters (coils and/or capacitors
between the amplifier outputs and 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 f ilters, which cut off frequency content at
the input to the amplifier. Active filters are more
stable than passive filters and do not introduce
extraneous resistance, which can degrade
subwoofer performance.

The active filter built into the XD200/2 can
be used to eliminate potentially harmful and/
or undesired frequencies from making their way
through the amplifier sections to the speaker(s).
This serves to improve tonal balance and to avoid
distortion and possible speaker failure. Correct
use of this filter can substantially increase the
longevity and fidelity of your audio system.

1) “Filter Mode” Control: The XD200/2

employs a 12dB per octave filter which can be
configured as a high-pass or low-pass filter
type, or defeated completely by way of the
three-position “Filter Mode” switch:
“Off”: Defeats the filter completely, allowing
the full range of frequencies present at the
inputs to feed the amplifier. This is useful for
systems utilizing outboard active crossovers or
requiring full-range reproduction from one or
more of the XD200/2’s channel pairs.
“LP ” (Low-Pas s): Configures the filter to
attenuate frequencies above the selected filter
frequency at a rate of 12dB per octave. This is
useful for connection of subwoofer(s) to the
XD200/2 in a bi-amplified system.
“HP” (High-Pass): Configures the filter to
attenuate frequencies below the selected filter
frequency at a rate of 12dB per octave. This is
useful for connection of component speakers to
the XD200/2 in a bi-amplified system.

2) “Filter Freq. (Hz)” The filter frequency

markings surrounding this rotary control
are for reference purposes and are generally
accurate to within 1/3 octave or better. If you
would like to select the filter cutoff frequency
with a higher level of precision, consult the
chart in Appendix B (page 13).

Tuning Hint: If you are using the XD200/2
to drive a subwoofer system (“LP” mode), a
component satellite speaker system (“HP” mode)
or both, 80 Hz is a good baseline “Filter Freq.

(Hz)” setting. After properly adjusting the “Input
Sens.”, as outlined in Appendix A (page 12), you

can fine tune the “Filter Freq. (Hz)” control to
achieve the desired system frequency response.

REMOTE LEVEL CONTROL OPTIONAL

With the addition of the optional Remote
Level Control (HD-R LC), you can control the
volume of the XD200/2 from the front of the
vehicle. This is useful for subwoofer level control,
rear channel level control, center-channel level
control or even as a master volume control for
the system.

The HD-RLC connects to the jack labeled
“Remote Level Control” on the Connection Panel
of the amplifier using a standard telephone cable
(supplied with the HD-RLC). If desired, multiple
XD (and HD) amplifiers can be controlled from
a single HD-RLC controller using a simple phone
line “splitter” and multiple phone cables.

When connected to the amplifier, the
HD-RLC operates as follows. At full counter­clockwise rotation, the audio will mute
completely. At full clockwise rotation the level
will be the same as if the HD-RLC was not
connected at all. In other words, it operates
strictly as a level attenuator.

PREOUTS

The XD200/2 incorporates a pass-through
preamp output section, so that additional
amplifiers can be easily added to the system.

The preamp output delivers the same signal
that is connected to the Amplifier Inputs. This
can be useful for feeding a subwoofer amplif ier
when the XD200/2 is being used to drive front
speaker systems.

Note: The preamp output signal is not affected by
any crossover filter selected (if the input signal is
full-range, the preamp output will be full-range).

9

SPEAKER OUTPUTS

The XD200/2’s speaker outputs are designed
to accept 16 AWG - 8 AWG wire. To connect the
speaker wires to the amplifier, first back out the
set screws on the top of the terminal 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 the terminal block,
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 screw.

The XD200/2 is designed to deliver power into
speaker loads equal to or greater than 2 ohms
when using a “stereo” conf iguration and speaker
loads equal to or greater than 4 ohms when using a
“bridged” configuration.

Speaker loads below 2 ohms nominal per
channel (or 4 ohms bridged) are not
recommended and may cause the amplifier
to initiate a protection mode which reduces
power output.

BRIDGING CONSIDERATIONS

Bridging is the practice of combining the
output of two amplifier channels to drive a single
load. When bridged, each channel produces
signals of equal magnitude, but opposite polarity.
The combined output of the two channels
provides twice the output voltage available from
a single channel. The XD200/2 has been designed
for bridging of its channel pair without the need
for input inversion adaptors.

To bridge the XD200/2, use the “Left +” and
“Right –” speaker connectors only (the
“Left –” and “Right +” remain unused). When
bridged, the amplifier will deliver optimum
power into a 4 ohm load.

When the X D200/2 is bridged, it
will deliver 200W x 1 into a 4 ohm load or
150W x 1 into an 8 ohm load. Operating a
bridged XD200/2 into a load lower than 4
ohms is not recommended. Because a bridged
pair of channels requires that both channels
receive input, you need to connect both left
and right inputs to the source unit. Connection
of only one input will result in reduced power
output, increased distortion and can cause
the amplifier to overheat. Do not do this!

When the XD200/2 is operating in bridged
mode, the output will be in mono (only one
channel). This mono channel can contain right
channel only information, left channel only
information or the sum of the information from
both the right and left channels. In order to
achieve one of these options, configure the inputs
to that pair of channels in one of these two ways:

1) Left Channel Only or Right Channel Only

Information: If you wish to send a lef t-only

or right-only signal to the XD200/2, use a
“Y-Adaptor” to split the single channel signal
into both left and right RCA inputs. This
option is useful when using one XD200/2
to drive left channel speakers only and the
another XD200/2 to drive right channel
speakers only.

2) Left + Right Channel Information:

When bridged and fed by a stereo input,
the XD200/2’s channels will automatically
combine the left a nd right channels into
a summed mono (left + right) channel.
This option is useful when using a bridged
XD200/2 to drive a subwoofer system
or a summed mono center channel.

10 | JL Audio - XD200/2 Owner’s Manual

STATUS LED / PROTECTION CIRCUITRY

There is a single multi-color LED on the top
surface of the amplifier to indicate the amplifier’s
operating status.

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

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

3) Constant Red: Indicates that the
amplifier has exceeded its safe operating
temperature, putting the amplifier into a
self-protection mode, which reduces the
peak power output of the amplif ier. When its
temperature returns to a safe level, the red
light will return to green and the amplifier will
return to full-power operating mode.

4) Constant Amber (yellow): Indicates
that an over-current condition has occurred
and is accompanied by a muting of the affected
channel(s). Because the muting behavior may be
very short in duration, it may manifest itself as
an audible, repetitive ticking noise in the output.
Over-current conditions can be caused by a
speaker impedance lower than the optimum load
impedance range for the amplifier or a short­circuit in the speaker wiring. The latter can result
from a short circuit between the positive and
negative speaker wires or between either speaker
wire and the vehicle chassis. The “Status LED”
will remain amber for a few seconds, even if the
over-current condition is of a very short duration.
This functionality can be used to diagnose a
short-circuit by only connecting one channel at
a time. The “Status LED” will turn amber when
you connect the channel that is experiencing

the problem and turn the volume up.

5) LED off / Amplifier Shuts Off Unexpectedly

The only condition that will shut down
an undamaged XD200/2 completely is if battery
voltage or remote turn-on voltage drops below
10 volts. The “Status LED” will turn off when
this occurs. The amplifier will 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 fails or malfunctions, please
return it to your authorized JL Audio dealer so
that it may be sent in to JL Audio for service.
There are no user serviceable parts or fuses inside
the amplifier. The unique nature of the circuitry
in the JL Audio amplifiers requires specifically
trained service personnel. Do not attempt
to service the amplifier yourself or through
unauthorized repair facilities. This will not only
void the warranty, but may result in the creation of
more problems within the amplifier.

If you have any questions about the installation or
setup of the amplifier not covered in this manual,
please contact your dealer or technical support.

APPENDIX A:
Input Sensitivity Level Setting

Following the directions below will a llow the
installer to adjust the input sensitivity of the
XD200/2 simply and easily in just a few minutes
using equipment which is commonly available in
installation bays.

Necessary Equipment

• Digital AC Voltmeter

• CD with a sine-wave test tone recorded at

0 dB reference level 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 the spea ker(s) from the

amplifier’s speaker output 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
maximum (if used to feed the XD200/2).

3) Turn the “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 the chart on this page, determine the target

voltage for input sensitivity adjustment according
to the nominal impedance of the speaker system
connected to the amplifier outputs.

6) Verify that you have disconnected the speakers

before proceeding. Play a track with an
appropriate sine wave (within the frequency
range to be amplified by the XD200/2) at 3/4
source unit volume.

7) Connect the AC voltmeter to the speaker output

connectors of the amplifier. If the channel
pair is operating in stereo, it is only necessary
to measure one channel. If bridged, make sure
you test the voltage at the correct connectors
(L+ and R–).

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

target voltage is observed with the voltmeter.

9) Once you have adjusted the XD200/2 to

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

Do not increase any “Input Sens.” setting for
any amplifier channel or channel pair in the
system beyond the maximum level established
during this procedure. Doing so will result in
audible distortion and possible speaker damage.

It will be necessary to re-adjust the

“Input Sens.” for the affected channels if any
equalizer boost is activated after setting 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
require re-adjustment.

APPENDIX D: TROUBLESHOOTING
“How do I properly set the input sensitivity on my amplifier?”

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

maximum, low-distortion output.

“My amplifier doesn’t turn on.”

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

possible for a fuse to have poor internal connections that
cannot be found by visual inspection. It is best to take the
fuse out of the holder for testing. If no problem is found with
the fuse, inspect the fuse-holder.

Check the integrity of the connections 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 connection is tight.

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

amplifier. In some cases, the turn-on lead from the source unit
is insufficient to turn on multiple devices and the use of a relay
is required. To test for this problem, jump the “+12V DC” wire
to the “Remote” terminal to see if the amplif ier turns on.

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

Check the speaker wires for a possible short, either between the

positive and negative leads or between either speaker lead
and the vehicle’s chassis ground. If a short is present, you will
experience distorted and/or attenuated output. The “Status
LED” will turn Amber (yellow) in this situation. It may be
helpful to disconnect the speaker wires from the amplifier
and use a different set of wires connected to a test speaker.

Check the nominal load impedance to verify that each channel

of the amplifier is driving a load equal to or greater than
2 ohms in stereo mode (4 ohms bridged).

“My amplifier’s output fluctuates when I tap on it or hit a bump.”

Check the connections to the amplifier. Make sure that the

insulation for all wires has been stripped back far enough to
allow a good contact area inside the terminal block.

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

contact with the input jacks on the amplifier.

14 | JL Audio - XD200/2 Owner’s Manual

“My amplifier shuts off once in a while, usually at higher volumes.”

Check your voltage source and grounding point. The power supply

of the XD200/2 will operate with charging system voltages
down to 10V. Shutdown problems at higher volume levels
can occur when the charging system voltage (or remote turn­on voltage) momentarily drops below 10V. These dips can
be of very short duration mak ing them extremely difficult
to detect with a common DC voltmeter. 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 alternator to the batter y. Many vehicles employ small (10
AWG - 6 AWG) wire to ground the battery to the vehicle’s
chassis and to connect the alternator to the battery. To prevent
voltage drops, these wires should be upgraded to 4 AWG
when installing amplifier systems with main fuse ratings
above 60A. Grounding problems are the leading cause of
misdiagnosed amplifier “failures.”

“My amplifier turns on, but there is no output.”

Check the input signal using an AC voltmeter to measure the

voltage from the source unit while an appropriate test tone is
played through the source unit (disconnect the input cables
from the amplif ier prior to this test). The frequency used
should be in the range that is to be amplified by the amplifier
(example: 50 Hz for a sub bass application or 1 k Hz for a full
range / high-pass application). A steady, sufficient voltage
(between 0.1 and 4.0-volts) should be present at the output of
the signal cables.

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

the previous check item (after plugging the input cables back
into the amplifier) test for output at the spea ker outputs of
the amplifier. Remove the speaker wires from the amplifier
while doing this to prevent unpleasant noise and possible
speaker damage. Turn the volume up approximately half
way. 5V AC or more should be measured at the speaker
outputs. This output level can vary greatly between
amplifiers but it should not be in the millivolt range with
the source unit at half volume. If you are reading sufficient
voltage, check your speaker connections as explained below.

Check to ensure that the speaker wires are making a good

connection with the metal inside the terminal block. The
speaker wire connectors are designed to accept up to 8 AWG
wire. Make sure to strip the wire to allow for a sufficient
connection with the metal inside the terminal block.
