These are two heavy duty 12 inch competition sub woofers made by Volfenhag. They are in a good sized custom cloth box. They are made of alluminum and pump out a lot of bass. Each sub cant withstand 1,000 watts. I had these in my ford explorer and they worked great. I will even throw in some cables for easy hook up.
