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.

3. Conﬁ guration The following diagrams show the most common conﬁ gurations for your Kicker ZX

series ampliﬁ er.
