Hello, What you see is a custom made enclosure for a JL Audio 10" W-3 sub that fits snug under the rear sway bar. It is wrapped in black vinyl and sounds great.

$250 for sub and enclosure plus actual shipping. I believe shipping will be on the high side and I am also listing this on Craigslist (Houston). If you are SERIOUS, I will go to the UPS store and get the shipping estimated before you commit to buying.

PS. There is a speaker wire terminal on the left side of the box if you are facing the sub.

PM me any questions, thanks
