[QUOTE="winkychevelle, post: 8811472, member: 611804"] I don't think i mentioned it prior but it shows in the pic. I put aftermarket carpet in and removed the factory vinyl flooring. The aftermarket carpet had a heavy mass loaded vinyl backer on it. This made legitimately the biggest difference in my sound stage I think so far. It quieted road noise significantly and reduced reflection distortion alot since carpet absorbs and traps stray sound waves. I've also done the pcm bypass to control my alts voltage. It's set at 14.8v for the agms I'm using now but I can set it up to 15.5v[ATTACH type="full"]42901[/ATTACH][ATTACH type="full"]42902[/ATTACH] [ATTACH type="full"]42903[/ATTACH] [/QUOTE]
