I grounded my amp to a bolt under my seat. My amp has a metal casing, and it hits the metal that the amp is grounded to.. I think it may have to do with why my subs play sporaticaly and loud out of no where even when my volume is at 0. Could having my RCAs and power wire together for about a foot (then they go seperate ways) have anything to do with it? Also, should my RCAs be plugged in the Amp input or output?
