Dave, you have to understand a couple things:
1 - mp3car.com is all about instlaling PCs in vehicles. It's not a general purpose car audio information site. You are far more likely to get a timely response on a forum that caters specifically to car audio.
2 - There are literally hundreds of models of 6.5" speakers. I suggest going to a major car audio reseller like Crutchfield or CarDomain and compare makes/models to narrow your search down to a few makes/models.
