I just bought some new speakers, 2 pairs of the Rockford Fosgate Punches to be exact. They are 6.5" and when i installed them in the front no problem. When i installed them in the rear doors, the window hits them when it goes all the way down, and in fact it does not go all the way down anymore. Im thinking it is the rear door brackets since i didnt change them out that is causing this. If you had any problems like this plz post thanks.
