Google Sketchup 2GS subwoofer enclosure
 

I thought I'd share my Google Sketchup project file with everyone. It should fit in the narrow, raised part of the trunk against the rear seat. All the measurements were taken with the center seat belt mechanism still mounted in the rear deck, therefore I provide a slant on the top to clear it. The rear panel is also slanted to account for the slant of the rear seat. My goal to try and make use of all the space I had available so I could install my 15" and get at least 2 cu ft of air space. Using an enclosure calculator, I'm seeing about 2.7 cu ft of volume. It shouldn't come any further than the raised area of the the trunk still leaving access to the spare tire. I'm no sketchup expert. I've used it enough to aid me in designing my home theater sub (which turned out great!) and this. Feel free to modify it for your application.

Where are you going to mount your amp?

Still working on that part. I'm considering building an amp rack in the floor of the trunk, raising it to the same height of the area where the enclosure will be. I'll need to work out still being able to access the spare with all that equipment on top of it.
