INSTALLATION
Mounting: Choose a dry, 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. Drill four holes using a 7/64" (3mm) bit and use the supplied #8 screws to mount the
amplifi er.
Wiring: The KXM amplifi er has dual input sensitivity differential RCA inputs which will receive either high or low
level signals from your 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 (make sure you set the KXM
amplifi er's input level switch to "HI"). Alternatively, the signal can be delivered to the amplifi er using the low-level
RCA outputs on the source unit. Set the input level switch on the end panel of the amplifi er to "LO". Either input
method will provide a low-level output signal at the amplifi er's RCA output, which effectively passes the audio
signal to another amplifi er or component. 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.

Disconnect the ground wire from the vehicle's battery to avoid an electrical short. Install a fuse within 7" (18cm) of
the battery and in-line with the power cable connected to your amplifi er. Connect the ground wire to the amplifi er,
then connect this wire to the negative battery terminal. If you ever need to remove the amplifi er from the vehicle
after it has been installed, the ground wire should be the fi rst wire disconnected from the amplifi er.
