So I have had a 350W 12" Crunch sub woofer in my Honda for almost 5 years now. The enclosure was built by one of my former roommates for his home theater so it never really fit well in the back of my car. I spied a particle board cabinet on its way out of my friend's storage unit and claimed it for a new cabinet since I'm *thrifty* :) In all I spent about $7. The 150W 8" I put in was from a previous project. The enclosure is sealed and filled with 20oz of polyfill. The outside dimensions are 20x12x14 inches.
