Installation

1.Mounting Choose a structurally sound location to mount your Kicker amplifier. 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 amplifier. If possible, mount the amplifier in the climate-controlled passenger compartment. Drill four holes using a 7/64” (3mm) bit and use the supplied #8 screws to mount the amplifier.

2.Wiring Disconnect the vehicle’s battery to avoid an electrical short. Then, connect the ground wire to the amplifier. 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 amplifier 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 amplifier, the ZX amplifier’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 amplifier using RCA

CONFIGURATION

interconnect cable. If a low-level stereo RCA output is not available on the source unit, the signal can be delivered to the amplifier using the high-level speaker outputs on the source unit. Set the input level switch on the end panel of the amplifier to “HI”. Crimp and solder RCA connectors to the end of the speaker wire running from the high-level speaker outputs on the source unit and connect the wire to the RCA Inputs on the end panel of the amplifier as shown in Figure 1. Either input method will provide a low-level output signal at the RCA output, which effectively passes the audio signal to another amplifier or component. Keep the audio

at a 90 degree angle.

Install a fuse within 18” (45cm) of the battery and in-line with the 8 gauge power cable connected to your amplifier. If you ever need to remove the amplifier from the vehicle after it has been installed, the ground wire should be the last wire disconnected from the amplifier--just the opposite as when you installed it. See the fuse chart on the following page for power and ground wire size, and fusing recommendations.
