I've got 2 15" Concept CPT-15s from my high school days when i used to work at a car stereo shop on Rockville pike. I used them for like half of a year, then my 4runner was sold, so these have been sitting in storage.

They handle 880w RMS each and each sub is dual 2-ohm (so u can run each sub at 4 ohms or 1 ohm).

$200 is asking price. pics will be up soon. If you have an amp hooked up already, I'd be more than happy to plug the box into your setup to demo it. I've got the original boxes, manuals, etc. and the box is 3/4" MDF so everything is top quality.
