Installation
Mounting
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
automobile’s luggage compartment can reach upwards of 140°
Fahrenheit (60° Celsius). An amplifier mounted here may require
additional cooling tactics such as fans or venting ducts to the
passenger compartment to allow cool operation. If possible,
mount the amplifier in the climate-controlled passenger
compartment.
Remember the controls on top of the amplifier will need to be
accessible for adjustment. 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 EndKap. This
will give you access to the mounting holes in the amplifier and all
wiring connections.
With the EndKap removed, drill four holes using a 7/64”
(11mm) drill bit and use the supplied #8 screws to mount the
amplifier.

Installation
Wiring
Signal can be input into the amplifier using either the low level
RCA input connections or the high level (speaker level) input
connections. Using the low level RCA connections is the
preferred method. Use the high level inputs only if your source
unit does not have low level RCA type outputs.

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!
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
potential of alternator noise and electrical interference.
When working with power connections it is always
recommended that you disconnect the battery to prevent
accidents.
