Well its not a 12" but it is a JL W3v2. This is a 10 inch sub, but I'm sure you could easily fit a 12 in this space as well.
I put matching carpet on the box before I installed it, but here are some pre-carpetted photos I found.
Hope this give you some ideas:
test fitting the box behind panel. I had planned on using the original kick panel, but it worked out better to just rip the carpet off of it and make a new one out of mdf.
Laying on the glass. Makes it waterproof and air-tight.
More glass, the angle of the face matches up to the kick panel. Just a little caulk between the two 9.25 inch holes to make sure there is a seal.
Finished, hits pretty hard. I had to take the change out of the side tray because it was shaking it too hard and causing a ruccous.
