well, two things i will recommend
dont do the svt box, its nice and all, but it will take a LOT of work to get the sub to fit and sound right
i would say get the molded enclosure, thats pre-fabbed for either a 10 or 12
i know someone had linked to a seller on ebay on here that was selling them. i dont have the link though
OR
make a false floor, and use l-brackets to hold the box down
