Anyone use one of those 6x8 to 6x9 adapters yet and know if they fir behind the door panels ? It looks like they will but i haven't tried yet. Maybe cut out the panels ? I need a good solution to replacing my stock speakers (non-bose) without changing my stock deck, and getting better sound with some freaking bass thump !! I have a 2010 MS3 and my ONLY complaint is that the stock speakers are weak.
