As for the rattiling I suggest pulling the upolsttry down off ur trunk lid and adding in two pieces of metal strap it will stiffen things up. Then put ur dynomat on. And even further put some roll on Bedliner on top of that.
The only way to properly fix it is with a better battery. My choice is a kinetics. They r kinda pricey but tits a tremendous difference. I had dd system pushing 7000 watts with a kinetics 3500 and never had a problem on the stock alternator. I would suggest a 2500 u can pick them up usually for...
i no this kinda sounds stupid but check ur motor mounts! my buddys car was making a knocking noise in the tranny when clutch was engaged, i crawled underand found a bbusted motor mount. put a new ones on it and problem was solved!!!
