I have a 12" JL audio sub in an obcon ported box with a 1000 watt pioneer amp mounted on top. Not sure of the specs on the sub. my old one blew up and my buddy sold me this one. I only used it for about a month before i sold my car and took it out. There is nothing wrong with any of it. just taking up space and i need the cash. just the amp and box are worth over $200. So that's what im asking for it but i WILL negotiate! Call or text anytime. I will get pictures as soon as i can!
