found this helpful.A great help on installing a sub woofer that wouldn't fit.
I would recommend this. It worked great. I painted it black, installed it and than the subwoofer. No problems at all and a life saver.

Bought 2 of these to space out a HUGE 10. Sprayed them in bed liner and installed. Doesn't look the best but got the job accomplished quickly.

I'm just still waiting on the subs I ordered back in November of 2022,once I get them I can actually use the rings I ordered
Update.
