He made it to perfectly fit the Arc Audio Flatline 12, 12" woofer. It's a high output SQ subwoofer...so it only needs 1.0 Cu. Ft. of sealed goodness. I didn't get a before pic, but it was a standard birch box with a SHAT-TON of screws in it.....my job? Make it look puuurdy.
I 100% sealed the box inside with each and every corner/joint receiving about a 1/4" of resin 45's. Then the entire internal and external surfaces were resin'd to be waterproof and leak proof.
After that, a few good hours of body work were put into the face plate to make it smooth and ready to go. A 3" hole was cut out for a heater vent. Everything got 5 coats of DupliColor Bedliner with the subwoofer grill getting a nice gloss coat of White to match the boat a bit better.
I installed some gnarly 1/2" Steel bolts for speaker terminals so that it's easier to install and the box stays sealed.
