Dansauto...I have recently installed a 10" JL Audio W3 into the space between the driver and passenger seats. The back-panel was removed, a custom enclosure made, and the entire panel was recasted(in the car) in fiberglass to ensure a factory look and fit. In addition, I installed a Sony MP3 player for the dash(a single MP3 encoded disc holds ~150 songs; thereby ensuring maximum space in the trunk and no clutter from discs laying adrift), MB Quart 5 1/4 components and tweets in the doors(using the stock mountings) and a 3 channel chrome Xtant amp in the trunk. I then had a beauty board made to cover the amp as to protect it from the windows/top if I decide to put them in the trunk. I finished the job with plenty of red neon in the amp as well as above it, to give it the show car appeal. If you wish, as soon as I get some pics on disc, I'll forward them to you.
