Installation . . . as easy as 1, 2, 3
1. Mounting Choose a structurally sound location to mount your Kicker amplifier. The controls on the
top of the amplifier need to be accessible for adjustment. 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 between the
battery's negative post and the vehicle
chassis of this same gauge (or larger) is
recommended.
Use a twisted pair of RCA (low-level)
interconnect cable to feed the audio
signal to the amplifier. Only use speaker
wire (high-level) inputs if your source unit
does not have RCA type outputs. 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 (P.A.S.T.).
Keep the RCA 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
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 chart below for power and ground wire size, and fusing recommendations.
3. Configuration The following diagram shows the most common configuration for your Kicker ZX
series amplifier.
OneChannelOperation These ZX amplifiers 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.
