i got around to putting my aftermarket head unit in. once that was in, and i could control the frequencies that were sent to the speakers, then there was no rattle, no problem. before, i had thought i'd blown the speakers or something...but then after that they were workin just fine...once you get the low frequencies off of em they work great. tweeters mostly come wtih their own crossover or something so i've been told, to kinda filter out the low end stuff it obviously doesn't need to play. (i know on some aftermarket ones i was lookin at the guy said it did that...i'm not sure if all tweets are that way) but yea...even if you got just a crossover control or SOMETHING to take the low end outta the stock ones, that SHOULD do you fine.
