you upgrade the 3 major grounds under the hood to help keep voltage up especially with systems and stuff like that, i think it goes like this
battery ground to frame
engine ground to battery
engine to frame
i dunno if those are right for sure tho

its the 3 main power wires in your car, it goes::

alternator to positive battery+
negative battery- to chassis (dead ground)
engine ground to chassis

I just did the Big 3 last weekend. Before, my voltage was dropping to about 12.4 on the heavy bass, now it stays around 14.4 all the time....and no more dimming!
