4 | JL Audio - XD200/2 Owner’s Manual
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).
Additional 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 amplifier/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.
