I have 2 - 12" Infinity Perfect DVC subwoofers that I want to get rid of. They were used for only a couple of months. I've had them for a little over a year, but never hooked them up in the car. They are in mint condition. Retail on these are $279. Buy both for the price of one. Here are some specs on them.
