I just recently replaced my stock Ford Explorer speakers, front door, with some Kenwood KDC-???? 6-1/2! TELL ME WHY, the shop that I bought them from assured me that the explorer had 6-1/2s in the front but when I removed the door panel, there where 6x8s! What the hell is a 6x8? lol I've never even heard of such size. Does anyone know a good 6x8s? I'm going to need some to keep up with my SD2.5 15's
