So the other day my sub woofer just stopped working out of no where and apparently for no reason. I have a Alpine 1000W mono amp with a JL 12in sub. I was wondering if you guys could help me diagnose the problem. The amp is still is on, and I ran all of the wires back to make sure if something didnt get disconnected. The bass just plays over my regular car speakers.I was wondering if you guys could help me diagnose the problem
