Awesome. Cheers for the info. If you remember, what is the OD diametre of the ring you cut? just purchased it, and wanna have it all ready to install once i receive it...
Cheers again
No Idea sorry. There is a template in the box that I used. It's actually part of the box you have to tear/cut out.
If the Sub is 8" I would think that the OD of the ring would be around 9.5" at a guess.
