ZXM AMPLIFIERS
ZXM.4-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: Disconnect the vehicle’s battery to avoid an electrical short. Then, connect the ground wire to the
amplifi er.
The ZXM amplifi er has dual input sensitivity differential RCA inputs which will receive either high or low level
signals from your car stereo’s source unit. Ideally, when connecting the source unit to the amplifi er, the ZXM
amplifi er’s input level switch should be set to “LO” and a low-level signal should run from the source unit’s stereo
RCA output to the stereo RCA input on the end panel of the amplifi er using RCA interconnect cable. If a low-
level stereo RCA output is not available on the source unit, the signal can be delivered to the amplifi er using the
high-level speaker outputs on the source unit. Set the input level switch on the end panel of the amplifi er to “HI”.
