I had a question bout a speaker size fitting in the front door, would a 6.75 in speaker fit in the place of the 6.5 that i have there now?? bc i just got some new speakers that are a lot better in sound but they are a bit bigger and depth is larger. please get at me if anyone knows anything.

 

yes. However you may need to modify or build a new speaker bracket.

 

A much larger speaker will fit. I have 7" speakers in my door and I'm pretty sure you can get an 8" in there with the right mounting plate.
