6X8's all around. I have kenwood 6879ie 2-ways for all four. For the door, take off the whole door trim panel. For the rear, take off the mesh grilles. If you buy new speakers from crutchfield, they come with instructions on how to replace the speakers.

Besides, human hearing range is from 20-20,000 Hz. why go up to 30-40,000? If you have the tweeters next to the mirrors (like i do), then the higher frequecies don't make that much of a difference anyway. my 6x8's are from 30-30,000, and my subs are cutoff above 120Hz.

Out of curiosity, what's the point in doing all that to get 6x9's in when you san easily find 6x8's? Sure they go a little lower on the frequency response, but if you put in a sub it doesn't really make much difference.
