[QUOTE="Blasphemy, post: 6843332, member: 621845"] Okay, my roommate found a piece of 1.5-2 feet piece of 1/0 wire laying around. So we thought it might be a good idea to upgrade the battery negative to chassis ground wire because stock is like 10-12g. We didn't take the stock wire off. Stock battery negative to engine is like 8g. Previous owner put 4g from alt to starter, starter to battery. So here is the problem, his subs aren't hitting as hard as they were (didn't change any amp settings) and his headlights are dimming a lot more than usual. What do you think it could be? Car - 1998 Contour SVT Battery - Optima Yellow Top Stock Alt. JVC KD-S100 Two JL 15W3D4 Two Xplod XM2002GT-R Amps:crap: (One amp per woofer) 4g to the amps 4g grounds [/QUOTE]
