WIRING INSTRUCTIONS
All power and speaker connectors will accept up to 8 gauge wire. It is very important
that the screws in the amplifiers’ 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:

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. Also remember that the current draw and the wire
requirements will be less if the amplifier is used at 4 Ohm stereo.
Inline fuse used at the battery: ZX460 = 60A
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.
