here are some pics of my spare mounted sub version 3.0. If you have read any of my other posts, then you have seen my differnt boxes. I am trying to market these, so if interested, please email or PM me. prices vary between 75-100$.

here are the specs

~.31 cubut feet air space
fiberglass bottom and sides
1/2" mdf top
(2 ) layers of 1/2" baltic birch plywooed to screw sub into
gold plated binding posts

I have the pioneer shallow mount 8" sub in it and it sounds great
the sq10 i had sounded good as well, but for sound quality, i think the 8" is a little better. I have plans on designing both a sealed and ported version for the ED KV7 6.5" sub, i think this will work great.

it fits under the stock covers, WITH all the wrenches in place. Takes up no space. I currently am powing this with a old kenwood 45x2 amp bridges, and it sounds great!.

Anyway, just seeing what you guys think. If i can get any interest, ill buy an extra spare whhel to use as a mold.
