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.
