I made this for my '08 AC, but have since decided that the space is more valuable. It's an Elemental Designs 11Ov.2 10" subwoofer in a .5CF sealed box made to eD's specifications: http://www.edesignaudio.com/product_...roducts_id=254. It's a dual 2-ohm VC wired for 1 ohm (see below). The box is 3/4" plywood and well-assembled. It's covered on 5 sides with grey automotive carpet and has black no-slip material on the bottom to keep it in place. The only "unfinished" part is that I chose not to buy a terminal plate and just drilled a hole for the leads.
I'd like to get $75 out of this. Negotiable, though. I also would prefer not to ship it, but will if you are willing to pay for shipping costs. It doesn't seem that heavy, but the scale says 22lbs. If you're around NE Kansas, we can meet.

The pictures pretty much speak for themselves, but if you have any questions, just ask. Thanks for looking.
