  • Page 2: Mounting Instructions

    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 where the screws will be driven that could be damaged. Check for wire harnesses, brake lines, fuel lines, gas tanks, etc.

  • Page 3: Wiring Instructions

    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.
  • Page 4 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.
