Cut the face of the box off, fit a piece of MDF to it, fiberglass'd it on, and bolted in the subwoofer.

Just did a quick and dirty job cause no one will ever see it.

I was so tempted to stuff a 10" woofer in there.. but it would have been choked.

Sounds great... hits harder than I ever thought an 8" would.

I highly recommend it!

Depending on the price after shipping, I might be able to get my hands on a factory subwoofer enclosure and do the same thing you have done. I finally relocated and rewired my amp this evening, but I have yet to finish the templates of the custom MDF enclosure I was going to make. I made a cardboard version of Zero's box, but it left a lot of room around side. I'm hoping that if I can get my hands on the factory enclosure, I'd do the same fiberglass/MDF combo you've done, along w/ enlarging the left, upper rear corner since I removed my gas door lock, so I'd fiberglass a bumpout for that extra bit of airspace.

How much, if any, polyfill did you stuff in there? I got the L5 instead of the L7, so I know it'll fit for sure after you posted up your initial pics
