About to do an install on one of these and would like to know what's the largest driver I can cram into the doors without modifying the door skin... so no cutting of the exterior door panel. I believe factory is 6.5" but will 8" or 10" fit?

 

From what I remember you can get a shallow 8 in there much like the early 90 Celica GTS. You won't have any more than 3" max I do belive
