Installation
1. 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.
2. 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 the source unit and connect the wire to the
RCA Inputs on the end panel of the amplifi er 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 amplifi er
or component. Keep the audio
signal cable away from factory wiring
harnesses and other power wiring. If
you need to cross this wiring, cross it
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
amplifi er. If you ever need to remove the amplifi er from the vehicle after it has been installed, the ground
wire should be the last wire disconnected from the amplifi er--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.
