for my fiberglass sub box

working on a pair of fiberglass subwoofer enclosures in my car, these pre-made mounting rings take a lot of work out of making a mounting point.

What is the inner diameter? My subwoofer requires a mounting diameter of 11 1/8"
Steve on Apr 25, 2017
Best Answer: My subs cutout diameter is 10 7/8", as I recall I had about an 1/8" of play all around, so I'm guessing you'll be snug, a little sanding might be needed.
