i installed 6.5 mbquart PSD in my ride front and rear. you really have to do a lil cutting to make it fit in the door panel. but the thing is the 6.5 are kinda big (depth wise), so you can't snap one of the clips back to the door. it still holds. it sounds great. i even tried putting 5.25 but they were jus too small.
i love watchin heads turn !!!!!!!
