Hello. I recently sold my Prius and am selling the fiberglass subwoofer enclosure that I made for my car. The internal volume of this sub is right at .6 cubic feet - perfect for most 10" subs. I had a JL 10w1v3 in it and it sounded extremely good. I am asking $275 shipped anywhere in the continental US. If you want to see pictures of how I made this enclosure, you can see them in this thread: Decided to Upgrade My Stereo and Build a Sub Box! | PriusChat
