Yeah it's weird. Places like Tweeter, Best Buy, Circuit City all say that 4th gen. Accords all have 6.5" speakers. Even the manual says it too, but the factory speakers that are in our cars are actually closer to 6.25, because the same problem happend to me. I wound up using the black plastic to house the speaker but did not screw it on one of the screw holes, and then finessed it to sit well inside the frame without coming in contact with the window when it is slid down.
