what's the difference in sound? i think that i can fit the 5 in the front and 6 in the back. 03 e320 HK sound. is it worth cutting a bigger whole for the 6?
what's a good amp to power these suckers? I want something good, and soomething that i can get about 50% of retail. 'ebay' or w/e. something better than jl audio amps :)
I wish polk would have signature reference amps, I would jump on that.
