Question about Rockford Fosgate Punch 500a2 Car Audio Amplifier
The spark could be from the capacitors in the amplifier charging. Make sure the main fuse from your battery is still good and also check all the fuses on the amplifier. Verify all the wiring is correct and make sure none of the wires from inside the positive cable are poking out and touching the vehicle or amplifier chassis. If you have a 1k ohm resistor, you can put it in series with the amplifier power line to slowly charge the capacitors. You can do that by following the directions from the link below. After doing all that, remove the 1k resistor, hook it all up and try it again. If it still doesn't work, make sure your remote wire coming from the head unit has a voltage on it when the head unit is on. You can get a cheap volt meter from a hardware store or wal-mart.
