Large enough to house some really deep 12s, this box is a beast and will belt out massive bass. Plus, with the convenience of a center shelf to mount your amp, you can install this box quickly and easily in your truck. Comes with gray carpet and features pre-installed screw in type terminal cups, not the cheap pop in kind most chinese boxes have. This box is built by us in the USA, not mass produced by chinese. We take pride in our work and it will show when you crank up your tunes. Don't settle for anything less than a Subthump box. Please note that due to speaker variability across the industry, Subthump takes no responsibility for subwoofers that do not fit this cabinet.
