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 the provided external fuse within 18” (45cm) of the ZX amplifi er and in-line with the power cable.
Install a second fuse within 18” (45cm) of the battery and in-line with the power cable connected to your
amplifi er. These ZX series mono amplifi ers deliver Kilo-Watts of power. We recommend an alternator

with a minimum 140 ampere output capacity, at least one extra battery located within 50” (130cm) to
the amplifi er, an extra fuse located within 18” (45cm) of the extra battery, all power and ground feeds
to be as short as possible, and utilize 12, 10 or 8 gauge speaker wire. See Figure 2. 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 below for
power and ground wire size, and fusing recommendations.

3. Confi guration The following diagram shows the most common confi gurations for your Kicker ZX
series amplifi er.

One Channel Operation These ZX amplifi ers are capable of operating into a minimum impedance of
2 ohms. If you are using multiple voice coils, the net impedance of the voice coils must be equal to or
greater than 2 ohms.
