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(s) of RCA (low-level)
interconnect cable to feed the audio signal to
the amplifier. If you are using only one pair of
RCA inputs, connect the RCA cable to the AMP
1 inputs. Push the fader button out, and all four
channels will work with a single pair of RCA
input cable. Push the fader button in, when
using two pairs of RCA input cables. 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.
Only use speaker wire (high-level) inputs if
your source unit does not have RCA type outputs. If you are using only one pair of high-level inputs,
connect the speaker wire to the AMP 1 input. Push the fader button out, and all four channels will work
with a single high-level input cable. Push the fader button in, when using both sets of high-level inputs.
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.
