Just to let anyone know, I replaced all 4 speakers in the door panels last friday. I actually bought 6x8 (5x7) Hi-Fonics 400watt 3 way speakers .........................they screwed right in with NO issues!! :hyper: Just another option for anyone who does not want to buy infinities..............Word of advice, pop the plastic out around the door handle beofre you pull the whole panel off. They sound a thousand times better than the stock speakers, extremely clear! Next I'm hooking up a 450watt amp to the stock radio with a 8in boss speaker in a low profile box with a built in amp. Let you know how that sounds.
