Hi, I am selling custom designed sub boxes in the affiliates section for 10 inch subs if you fancy a look.

I have made these with a 12 inch hole and successfully put a couple of JBL subs in, However the guy who i did these for has just bought a pair of infinity perfect 12s and these are to deep for the box.

Will fit with sanding down the rear board a few mm hopefully, if not will be making him some spacers!.

Depends on how important it is to you to have your seat back!
