I have a carpeted subwoofer box( dual 12") that fits in the rear trunk well of a 93-02 camaro/firebird. I haven't used it since at least 2009. It currently has Soundstream Mule 12" subwoofers in it. They do work good but look beat and had a hard life. Box is just a little dirty from sitting in my garage.
I'm asking $20 for just the box. And another $25 for the pair of subs.
Buy either or, or everything.
