i only have one battery and it has been moved to the trunk, right now i have battery grounded to the strut tower in the back and a ground in front going from engine to strut tower and another going from transmission to frame, im still not getting the best of electric, voltage drops on 1kwRMS audio but i even get a bouncing gauge with turn signal, was wondering if i am having bad ground ?

have all ground points been cleaned of paint to bare metal? if it was me i would run a 1/0 ground all the way to engine anyway and several 1/0 body grounds front and rear just for good measure but i tend to over do my electrical

welding cable is great i've been using it for about 20yrs. it sure beats most of this junk that's sold now.
