Mounting Instructions

When selecting a location to mount your Kicker amplifier be sure it is struc­turally sound and that there are no items behind the area that could be dam­aged by the screws. Check for wiring, brake lines, fuel lines, gas tanks, etc.

All amplifiers generate heat under normal operation. Be sure to choose a loca­tion that allows adequate ventilation for the amplifier. Also consider that the air
temperature inside an automobile’s trunk can reach upwards of 140 degrees
fahrenheit. An amplifier mounted here may require additional cooling needs
such as fans or venting to allow cool operation. If possible, mounting the amp in
the passenger compartment will allow cooler operation.

Remember that the controls on top of the amp will need to be accessible for
adjustment later. Keep this in mind as you choose your amplifier’s mounting
location.

Now that you are ready to mount your amplifier, use the supplied 3mm allen
wrench to remove the amplifier shroud. This will give you access to the mount­ing holes in the amplifier and all wiring connections.

With the shroud removed, you now have access to the four mounting holes in
the mounting feet and all wiring connections. Drill 4 holes using a 7/64” drill bit
and use the supplied #8 screws to mount the amplifier.

Wiring Instructions

Signal can be input into the amplifier using either the low level RCA input con­nections or the high level speaker level connections. Using the low level RCA
connections is the preferred method. Use the high level inputs only if your head
unit does not have low level RCA type outputs. Connecting to the amp with
either input will provide a low level signal at the output (PAST) jacks.

The use of twisted pair interconnects is recommended for all installations to
minimize noise. When routing these cables through the automobile, try to keep
them away from factory wiring harnesses and other power wiring. If you need to
cross any of this wiring do so at a 90 degree angle to reduce the possibility for
noise problems.

When working with power connections it is always recommended that you dis­connect the battery to prevent accidents.

The ground should be connected to the amplifier first before making any of
the other connections. This wire should be as short as possible (24 inches or less)
and connected to a paint/corrosion free solid metal area of the car’s chassis. Use
the same gauge wire as recommended for the amplifiers power connection to
the battery. Adding an additional ground wire between the car battery’s negative
post and the car chassis of this same gauge (or larger) is also recommended.

If you ever need to remove the amp 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.

A fuse must be installed within 18 inches of the battery to protect the power
wire feeding your amplifier. This fuse should be of at least the same value used
in the amplifier but no higher than the capacity of the wire. See the chart below
for wire size and fusing recommendations.

KX400.2 60A 4 GA
KX500.2 70A 4 GA

REMOTE BASS LEVEL CONTROL

When the crossover on your KX series amplifier is set to LO PASS, you have
the ability to control the output level of the amplifier from the driver’s seat
using the supplied Remote Bass Level Controller.

To mount the controller simply screw the metal bracket to the chosen location
and then slide the housing onto the bracket until it snaps into place.

Run the cable from the controller to the appropriate jack on the amplifier
chassis.
