All specs can be found here : http://www.behringer.com/EN/Products/EP2500.aspx I'm selling the subs I used this with (see my other posts), so I have no use for this. It's a great amp, but I'm moving to a small condo, and won't be using a big DIY sub anymore. In 10/10 condition, works excellent, and still have all original packaging. Until 7/28, I'm located in Charlotte NC. After that, it will be with me in Sarasota FL. Interested buyer is welcome to come inspect and test it. Due to weight, would prefer local sale if possible. If no interest locally, I will ship. Still sells brand new for $300+ shipping on amazon. Asking $200.
