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.
The KICKER CX Amplifi ers are capable of space-saving vertical mounting. Use a 2.5mm hex key (Allen wrench)
to loosen the endpanel, remove the existing brackets, then insert and tighten the double-slotted brackets to the
amplifi er as illustrated on the next page.
