For sale are 2 Hertz HX 300 12" Subwoofers in a ported box built to their specs by Audio Concepts. They are in perfect condition with nothing at all wrong with them. They hit hard and are the loudest subwoofers I have ever had in any of my cars. The box alone cost me $600 to have built last summer and the subs retail for about $400 each I believe. The box has a built in amp rack on the back portion. I am selling them because I am selling my car.
