i blew a fuse by the battery and put a new one in and it blew within a minute, but the subs worked fine, now when i out in a fuse, the subs sound like crap and the fuse still blows. it worked fine for almost a year untill about a week ago, i've unhooked everything from the amp and then re hooked it up, the fuse will stay good when the amp is powered until i plug the rca jacks back in. can anyone help?
