planning to put up some pics soon....i figured out what most of the rattling was coming from.....a few of the plastic pins that hold the reardeck/side valances that go up the back pillar somehow rattled off so ive replaced them and took some advice and used thin eggcrate type foam and no more rattles from that anyways....that doesnt nclude my trunk/spoiler tho i plan to dynamat tho.as for the power problems im having tho.........im picking up a new battery today its some type of optima that looks like a six pack .....from what people have recommended it seems to be the best for powering a system.i also looked around and i couldnt find a bigger alternator....but i did manage to come across something called the big 3 upgrade...which is similiar to what you were talking about with 1) alternator positive to battery positive, 2) battery negative to chassis, and 3) engine ground to chassis... can this be done to stock alternator or am i going to have to find a high output alternator?but simple things first....i basically need the new battery and to do the cable upgrades?
