Custom tooled gold plated connectors Assure maximum power transfer and damping.
Strapping Jacks Allows two amplifiers to be joined to produce Double Power.
Remote Bass Level Control Dash mounted for maximum control.
Three Year Warranty When purchased from and installed by Authorized KICKER dealer.
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 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 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 amplifiers 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.

Strapping Two KX.1 Amps(Double Power)
By using a Mono plug (available at Radio Shack) you can run two KX .1 amplifiers into one woofer. Minimum impedance 4 ohm for KX400.1, KX600.1 and 2 ohm for the KX1200.1. When strapped the Secondary amplifier controls are bypassed. See Tech. Brief for more info. on this configuration.
