Why does my Rockford Fosgate Punch get too hot?
If your Rockford Fosgate Amplifier is overheating: 1. Ensure the amplifier is properly mounted, allowing heat to rise. Mount the amplifier with the heatsink fins aligned vertically to allow free airflow. Check that the heatsink fins are free of obstructions such as carpet or seats. 2. If the issue persists, verify that the impedance of the overall system is not less than 2R as described on page 14.
How to fix turn-on pop noise in my Rockford Fosgate Amplifier?
To address turn-on pop noise in your Rockford Fosgate Amplifier: 1. Disconnect the RCA plugs from the amplifier and recheck the amp by turning the unit on and off. If the turn-on pop goes away, connect a delay turn-on module (Perfect Interface DT-1) to the amplifier. (See your Authorized Rockford Fosgate Dealer for more information.) 2. If the noise persists, disconnect the turn-on wire from the head unit and use a different +12 volt power source to turn on the amplifier (i.e., battery direct). If the noise is gone, use a relay to switch +12 volts auto power from the clean power source.
What to do if my Rockford Fosgate Punch won't play, but the remote turn-on light is on?
If your Rockford Fosgate Amplifier won't play but the remote turn-on light is on: 1. Unplug the head unit and test the amplifier with another working source unit (i.e., bench-test radio, walkman, etc.). If the amplifier plays, check the in-dash leads for cuts, breaks, and/or shorts. 2. If the amplifier still does not play, disconnect the existing speakers and connect a set of test speakers to the output of the amplifier (any type of speaker will do - i.e., simple home box type, bookshelf, raw speaker, etc.). If the amp plays, check for shorts or blown voice coils in the vehicle’s speaker system. If you are still having problems, have the amplifier checked out by an Authorized Rockford Fosgate Dealer.
