Gone guys....Had to pay to take it to the dump.
As for blueprints, there were none. It was made out of mdf and fiberglass. My buddy and I figured out what we needed for airspace for the subs and built a box that size using the trunk as the bottom of the box (using the spare tire well as air space). Then we laid the fiberglass in it, built a top plate, and trimmed it in using masonite and automotive carpet. It took forever but looked good when it was complete. I know it would have been quite a hike for most of you guys to come pick it up but you are looking at over $200 in materials and then the time to build it....80 hours combined between the two of us. FREE is one hell of a deal!
