Iggy will the Boston Acoustics 6.5 Pro series fit?
Mounting Depth 2-3/8" (60mm)
Mounting Depth with Spacer 2-1/16" (52mm)

 

It should fit. The stock basket is 2-1/2 inches deep. At 2-3/4 inches into the door frame, you hit the window when it's rolled down. Anything at 2-1/2 inches or less into the door frame and 1 inch or less on the outside of the door frame will fit and still allow the door panel to snap back in place. There is also a limit as to the diameter of the speaker basket. The door hole cutout is only around 4-1/4 to 4-1/2 inches wide. Most 6-1/2 inch speakers really want a 5 inch hole cutout. Sometimes you have to make a custom spacer to accomodate for this as well as drill a new hole pattern.

It sounds like this speaker is on the small side for a 6-1/2 inch speaker. That's good. It means that it will probably fit. Some oversized large 6-1/2 inch speakers like the MB-Quarts are impossible to fit without sawing out the door frame, etc.

Good luck!

Thanks Southbound!!

 

FWIW: I tried the 6.5s, and the installer said that quite a bit of mucking around would be required. He put in the 5s and I'm very satisfied with them. See my other post- search for boston acoustics.........
