Thank you to everyone for the great links and advice on putting some
real sound into my XJ. Here are two last questions:

1) Has anyone ever seen a 10" 3way woofer mounted INSIDE the rim of the
spare tire? If so, was the mounting hardware custom or off the shelf?

2) Is there room under the back seat for an amp plus capaciter? How
about for a CD Changer?

Thanks again!!!!!!
