What to do if my Rockford Fosgate 2.3 makes a noise (turn-on pop)?

A turn-on pop from your Rockford Fosgate Amplifier can be caused by a voltage spike entering through the input signal. To troubleshoot, disconnect the input signal to the amplifier and turn it on and off. If the noise is eliminated, connect the REM lead of the amplifier to the source unit using a delay turn-on module. Another cause could be a voltage spike from the remote turn-on lead. Try using a different 12 volt source for the amplifier's REM lead, such as directly from the battery. If this resolves the issue, use a relay to isolate the amplifier from the noisy turn-on output.
