Pro Tip: To get the best performance from your new KICKER Amplifi er and extend the warranty by 1 year, use genuine KICKER accessories and wiring.

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. Make the ground wire short, 24” (60cm) or less, and connect it to a paint-and-corrosion-free, solid, metal area of the vehicle’s chassis. Adding an additional ground wire of this same gauge (or larger) between the battery’s negative post and the vehicle chassis is recommended.

The ZX 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 ZX 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”. Crimp and solder RCA connectors to the end of the speaker wire running from the high-level speaker outputs on
