KXMA STEREO-SERIES AMPLIFIERS
OWNER’S MANUAL
INSTALLATION
Mounting:
Choose a structurally sound location to mount your KICKER amplifi er. Make sure there are no
items behind the area where the screws will be driven. Choose a location that allows at least 4” (10cm)
of open ventilation for the amplifi er. If possible, mount the amplifi er in the climate-controlled passenger
compartment. Drill four holes using a 7/64” (3mm) bit and use the supplied #8 screws to mount the
amplifi er.
Wiring:
The KXMA amplifi er’s RCA inputs will receive either high or low level signals from your car stereo’s
source unit. A high-level signal can be run from the source unit’s speaker outputs to the stereo RCA
input on the end panel of the amplifi er using the KICKER KISL as shown. Alternatively, the signal can be
delivered to the amplifi er using the low-level RCA outputs on the source unit. Keep the audio signal cable
away from factory wiring harnesses and other power wiring. If you need to cross this wiring, cross it at a
90 degree angle.

IMPORTANT SAFETY WARNING
PROLONGED CONTINUOUS OPERATION OF AN AMPLIFIER, SPEAKER, OR SUBWOOFER IN
A DISTORTED, CLIPPED OR OVER-POWERED MANNER CAN CAUSE YOUR AUDIO SYSTEM
TO OVERHEAT, POSSIBLY CATCHING FIRE AND RESULTING IN SERIOUS DAMAGE TO YOUR
COMPONENTS AND/OR VEHICLE. AMPLIFIERS REQUIRE UP TO 4 INCHES (10CM) OPEN
VENTILATION. SUBWOOFERS SHOULD BE MOUNTED WITH AT LEAST 1 INCH (2.5CM) CLEARANCE
BETWEEN THE FRONT OF THE SPEAKER AND ANY SURFACE.
