Perfect for custom install
Crutchfield Customer Review (What's this?)
I had to find a way to make a pair of good 5 1/4" speakers fit in the 4" cutouts on my Volvo 245 in the front doors. The stock adapters were cracked, broken, not quite big enough, and impossible to find a replacement. Bought these universal adapters and spent a couple of hours trimming them to get them to match the contour of the door panel. Had to adjust height to still clear window while gaining clearance to the dash. In the end, works great and very clean looking. The plastic is easy to trim and leaves a good edge when done. Would buy again.
