    Mounting Instructions When selecting a location to mount your Kicker amplifier be sure it is struc- turally sound and that there are no items behind the area that could be dam- aged by the screws. Check for brake lines, fuel lines, gas tanks, or wiring harness- es etc.

  • Page 3: Wiring Instructions

    Signal can be input into the amplifier using either the low level RCA input con- nections 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, RCA dummy plugs must be insert- ed 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! If you do not have dummy plugs available, simply using raw RCA ends or cutting the ends off of existing cables will be sufficient.
