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
diagrams show the most common
configurations for your Kicker ZX series
amplifier.
Two Channel Operation (Stereo) These ZX amplifiers are capable of operating into a minimum
impedance of 2 ohms per channel in stereo operation. See Figure 2.
Bridged Operation (Mono) ZX.2 series amplifiers are capable of operating into a minimum
impedance of 4 ohms when in bridged operation. See Figure 3.
Stereo and Mono Operation Simultaneously (SAMS) The ZX.2 series amplifiers are capable of
operating into a minimum impedance of 4 ohms mono and 2 ohms per channel in stereo
simultaneously with the use of passive crossovers. See Figure 4.
