I'm having trouble with the 40a BCM fuse. When I turn my aftermarket stereo up all the way it will pop the fuse sometimes. My car will shut off completely with the key still turned. Luckily it hasn't happened while driving. It seems pretty random though, as it will be fine some of the time before any trouble. It only happens when the stereo is all the way up, not half way or anything else. Anyone have any ideas?
