WIRING INSTRUCTIONS
All speaker connectors will accept up to 8 gauge wire, and the power and ground con-
nectors are designed for 4 gauge wire. It is very important that the screws in the ampli-
fiers’ terminal strips are very tight. An allen wrench is included for this purpose. Always
make the ground connection first when installing this amplifier and disconnect ground last
when removing it from the system.
Connect the ground wire, which is 24 inches or less, to a structural chassis member. Be
sure the connection is to bare metal and securely screwed or bolted. (It is not recommend-
ed to run the ground wire to the battery.) Run a positive wire of the size shown below
directly to the positive terminal of the battery and use a fuse of appropriate size within 18
inches of the battery.
This fuse protects the wire run from the battery.
Please refer to this wire gauge selection chart for minimal loss at full rated power under
test conditions:
Model Up to 4 ft 4 to 7 ft 7 to10 ft 10 to 13 ft 13 to 16 ft 16 to 22 ft
XS50 6 6 4222
XS100222200
When running the signal wires keep them away from all power wires in the vehicle to avoid
noise. If a signal wire needs to cross power wires, try to make the junction at 90 degrees.
This will have the least chance of picking up noise.
Note: in the case where the recommended wire size is larger than the amplifier’s connec-
tor, it may be necessary to use a power distribution block or inline connector to adapt
down to the size your amp will accept.
Inline fuse used at the battery: XS50 = 90A, XS100 = 150A (supplied with the amplifier).
IMPORTANT INFORMATION
PLEASE READ BEFORE INSTALLING AMPLIFIER
Your new KICKER power amplifier is equipped with a ZRX Active Electronic Crossover
Module installed in the Module Docking Port.
You may configure the ZRX to function as a low pass filter (12dB/octave at 80Hz) or
high pass filter (12dB/octave at 100Hz) by setting the switch on the ZRX as shown is the
illustration. The ZRX may also be set to bypass, in which case your amplifier will function in
a full-range mode. The ZRX affects only the amplifier in which it is installed. The amplifier’s
output RCA jacks carry a full-range signal regardless of the settings on the ZRX.
