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.

Warning: Use Only One....
Never Both At The Same Time!!
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!

Supplied 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 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.

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.
