I have a cali profile 1000M amp hooked up in my grand prix and just the other day it seemed to start messing up. The amp will power the subs up to a certain volume level, which is only volume level 3 and it can go up to volume level 40, and then the amp cuts off. Then a few seconds later it will cut back on then rite back off. The led light blinks and the subs dont get any power after that. If you can help me figure it out then write me bak please. thanks
