Without question, the wildest and most original subwoofer enclosure design in the history of car audio was our Bass Tubes subwoofers camouflaged to look like a Nitros Oxide System. Now, we've taken it a step further and made a SCUBA version for your boat! This 8” subwoofer is simply a Bazooka subwoofer with the patented Bass Tubes enclosure camouflaged to look like a Scuba tank. This unit comes complete with tank, cosmetic nozzle, braided line speaker wire, and a complete mounting kit.
