like it says above can anyone tell me the fitment sizes for the rear speakers without having to modify them?

 

mine are 6x9 but I think the non bose are 6.5

 

have you looked yet?

 

they should all be 6.5"

i know on 5th gens etc, the ex model accords came equipped with 6 1/2" speakers for the rear.

im not sure about 4th gens though, but its as easy as popping the trunk and looking at them...
