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. 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 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 chart on
the following page for power and ground wire size, and fusing recommendations.
