my sub recently got disconnected when i made a turn in my car and the bungee cables came loose. it flipped over and all the wires came out. some cables that came out included the wire that connected the neg part of the cap (in a clamp) to the GND part of the amp, and the other wire in the same clamp, connected to a screw agaisnt metal. i reconnected all these cables, put the 2 back in the clamp, and now i am having a humming noise out of my speakers. this noise i have figured out from these forums is because of an alterntor whine, since wen i push on the petal it changes the pitch of the humming. i have no been able to find tho how i actually fix this. hopefully someone can either link a forum or help me out. thanks guys!
