Whenever I open a door my sub and HU turn on. I know that the stock HU turned on because of the security settings and since I tapped that fuse the sub would turn on when the doors opened and it did but now my new HU turns on when the doors are opened. My Sub is also blowing fuses like nothing else. Every time I reconnect the batter my amp/sub fuse blows, why?
