I have a custom-made fiberglass subwoofer enclosure for a 10" subwoofer. It fits snugly around the spare tire in any Gen3 Integra, probably other gen's, and models too. It mounts using the stock retaining bolt that holds the spare tire and is prewired for a subwoofer. Asking $80 or best offer. Will provide pictures on request, email is SCarlblom1@hotmail.com
