The speaker box is a very high quality box by Atrend. It’s vented in the center, and has speaker hookups on the outside of both ends of the box to easily connect the speakers to your amp. The speakers are 12” JL Audio subwoofers. I think they’re the 12W3v3 model, but I’m not 100% sure on that. Overall, this is in really great condition. Came installed in a car I purchased, but I’m not real big on having subwoofers that can shake my whole car. They definitely work! Thoroughly tested them before taking them out of the car. I’m not an aftermarket car audio expert, so I went by a local audio shop and had them appraised. New, this setup cost over $700. I’m asking $500. I’ll consider reasonable offers, but please don’t offer me half of my asking price. That’s just annoying. If it’s still listed, it’s still available. I don’t hold items for people unless payment in full is received. The first one to put money in my hands gets it. Thanks for looking!
