Has anyone replaced the original speaker with aftermarket 6-1/2 units, and if so, how did you resolve the problems that top-mounting a speaker into the factory box creates? Most candidate speakers I've found will not recess, but
effectively add to depth of speaker box by their rolled edge and/or rubber
surround. This alters the box's relation to the upholstery panel, and may
nudge it into the path of window glass when lowered. Any guidance appreciated.
