Ahh Cartronics... We destroyed those cars in SPL and SQ To each his own, whatever works. But that was a few years ago... maybe someone came up with the ground everything byself concept while I was away idk. As far as alt "kicking out" juice and producing, I think cartronics mislead you. If anything the amp will malfunction or just plain shutdown but it WONT produce engine whine.... which is what this thread is about. Jacob, if you wanna ground everything seperate then have fun but don't waste your money on a lightning cap.
