Do they make an adapter to gofrom 6x8 to a 6 1/2 door speaker?

 

Sorta... they make a universal adapter that allows you to go from 6" x 9" to many different sizes. I used them in the front doors of my '05 screw. The only problem is there is very little plastic left after you dremel the sides for the 6.5" components. I think I paid $12 for the set from a local audio shop.

 

if you got the tools make them yourself, use 1/4 inch mdf board.
