My car subwoofer on and off randomly. When there's no sound from the subwoofer, the amp is still turned on and is not in protection mode. But i do notice that the subwoofer would turn on again, when i roll down the power windows. Anybody have any idea what the problem is?

Its hard to internet diagnose wiring issues. How are all the wires ran, where is everything located, do you have rca cables from the headunit to the amp or are you using a line out converter.

Check the ground, signal, and power wires for any nicks, cuts, or loose connections. Also check at the amp terminal blocks and fuse block for loose connections.
