I am running 6.5" kicker components in front and polk 6.5" in the rear tailgate, an alpine 4ch amp, and pineer head unit; sounds awesome.
The front kick panels in my sami had factory openings for 5.25" speakers, but my 6.5" fit in there just fine with no cutting (I did have to drill holes for mounting screws), and there was plenty of depth for the baskets.
If you have any questions, the people at Crutchfield are usually pretty helpful:
www.crutchfield.comThey don't always have the best prices, but if you have a discover card you can get 20% off by using your cashback bonus there, and an additional 5% through the shopdiscover website...these deals make them cheaper than anywhere, at least for me.
Their website also have very accurate dimensions for all of the speakers they carry, so you can do a little research there before you buy anything.
