i have a 00 gt without mach and want to replace speakers and h/u. what size are the stock speakers and what will fit? i want componets but dont want to have to mount the tweet by the mirror (was told that tweet should be close to midwoofer) and dont want to drill holes in my door cover. i have to turn my radio up at least half way to hear it over the exhaust which is not a problem. the problem is it sounds like ****. any suggestions??? will dynamat or something like it help with some of the interior exhaust sound or will i be wasting money?
