It's a sub with an amp built in was working fine . Then we tried to plug in another amp in to test speakers. We disconnected the amp/sub and used the same connections for the new amp and blew the fuse in the power cable we replaced the fuse. rewired the amp/sub and now its acting up. After it gets to a certain bass level the sub just sticks and plays a continuous sound and won't stop even if the head unit has its volume turned all the way down. Anyone have this problem before? Or can help?
