Yeah im in the process of doing this also, I have 2 8" audiobahns mounted the back there, but im in the process of mounting them so that the magnets of each speaker sticks up through the rear deck. Cutting that seat belt mount out was the biggest challenge but once thats done its fairly easy from there. I made boxes out of an quickcrete concrete tube, they fit perfect and look really nice, i got that Idea from someone on this board, but cant remember who, but they get the credit for it. I will post pics of these speakers as soon i get home from the middle of the Gulf of Mexico.
