I purchased my brothers audio setup and i have a VERY large sub enclosure I need to sell, it holds 4 12's, is ported properly, each sub is in seperate chambers. Custom built to fit in the back of his ford ranger xlt---this box held 4 Fosgate hx2's (power series)--this box was tearing his ranger up when he cranked up the volume, pieces were shaking loose and we noticed that the back window was so close to flexing out of place with the bass, This is for the serious bass competitor...PICKUP ONLY OF THIS...I'm located in Dunnellon Florida--near Ocala EMAIL ME AT chillcat34433@yahoo.com
