So I've been trying to find anyone with the same issue but so far no luck. Maybe someone can shed some light on this. I was driving home from work listening to music then all of a sudden the bass completely went out along with all the speakers except for the tweeters. I disconnected the amp from the trunk and plugged it back in and still nothing. Nothing works when amp is disconnected but when plugged in I just get tweeters. I'm assuming the amp is partially fried if there is no fuse.
