I have done this...I have a 12" in there....
All you need to do is Make a fiber glass box by doing the following:
1) Get rid of the bracket for screwing down the tire...and clean the entire well out good.
2) Get paste wax (Johnson&Johnson) and give the entire well including a bit of the lip a good 3-4 coats.....This is important if you want the box to be re-movable
3) Now paint the wax with Fiber glass Resin ( A bit at a time) and lay down fiberglass mat as you go....Cover the entire wheel well including a bit of the lip around it. Repeat this step two times alowing it to dry inbetween.
4) Gentially pry at the fiberglass the next day and it should pop right out....Now you just need to strengthen the box...by adding either more layers of fiberglass mat...or soak Fleece in resin and use that instead as it builds thickness quickly.
5) Use MDF to cut out the top piece...Cut out the 12" circle first....and fiberglass this right to the box.....fill in all holes from the inside to make sure it is air tight.
6) next secure it to the spare wheel well with bolts, install sub, and do whatever finishing you want.
