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 where the screws will
be driven that could be damaged. Check for wire harnesses, 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 automobiles trunk can reach upwards of 140 degrees
fahrenheit. An amplifier mounted here may require additional cooling tactics
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.

When using both sets of High Level inputs on the KX700.5, the supplied RCA
dummy plugs must be inserted into the AMP 2 inputs in order for the fader to
work properly. If the amplifier is being used in any other configuration DO NOT
USE THE RCA DUMMY PLUGS!

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 potential of
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.

KX-700.5 90A 4 GA
Remote Bass Level Control
When using the Remote Bass Level Control you have the ability to control the
level of the subs from the driver’s seat. To mount the controller simply screw the
metal bracket to the chosen location, 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.
