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.

life and realism into any audio system with this small, yet powerful, amplifi er and acoustic processor in
one. With simple, one-step, automatic audio calibration, you'll have drastically improved audio quality and

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.
