Nut Hair Trick, a truly AWESOME box for you... shave your nuts and save the clippings, and use them to carpet your next box. That would be epic, and the ultimate Nut Hair Trick!
To keep this thread on track, I'm glad to see a grille on that sub considering where it's placed. I've seen many subs beaten to death in the trunks of cars by groceries, etc. And that grille looks very nice.
The box would look sick, if it's sturdy enough, if you covered the top in cushioned vinyl to match the front of the boat there though.
