ive already checked all connections for about an hour today. disconnected everything and put it all back together. then took everything off one by one, and still nothing. everything is how it should be. the only thing i didnt check is the ground connected to the chassis. but i know its ok, because its on the bolt for the rear seat seatbelt, and thats tight.

could hitting the ground and power wire together cause this? maybe messed up the amp somehow? i dont have another amp laying around to see if thats it. i hooked up a different speaker, and the same thing happens, so i know its not the sub.
