Question about Rockford Fosgate Punch 500a2 Car Audio Amplifier
The B+ terminal on the amp goes to the Positive battery terminal with a fuse inline probably at least 60amp for this amp. The GND terminal of the amp goes directly to the chassis of the vehicle (metal) and try to keep the ground 18" or under. The REM terminal of the amp goes to the remote turn on wire from your deck, usually the BLUE wire. Some decks have 2 one for an amp one for a electric antenna. Dont hook it to the power antenna wire or your amp will only work when the radio is on. Won't work with the cd player. Hook the left and right inputs (rca) to your source unit (deck). Hook your speakers to the left and right channels of the amp with the correct polarity (+) (-) . Set the cross over on the amp HP-AP-LP for what ever application you are using it for like subs or components. There is a frequency adjustment for the crossover on the opposite side of the amp. This should be set in accordance with your crossover selector and speaker requirements. The punch bass knob should only be used with a subwoofer application. The left and right gain turn up or down the gains of the amp. (power output) These are set depending on the output voltage of your preouts (RCA) on your deck. A small flat head screw driver can be used. Set them between 1/2 and 3/4 if you dont know but make sure they are the same. Your ready to go. Hope this helps.....
