This loaded enclosure helps to eliminate the time spent trying to figure out what subwoofers will work best with an empty enclosure by offering you the best possible combination in one, easy to install solution. Designed to be a perfect OEM fit under the Gladiator's rear seat, you can finally add premium bass to your truck's cab without sacrificing any of the space so many audiophiles are reluctant to give up. The enclosure features two of our new VS-12 D4 1000-watt max power shallow mount subwoofers, which are pre-loaded and wired up internally for a 1-ohm final impedance load at the single speaker terminal wiring cup. (Ensure that your amplifier is 1-ohm stable before purchasing, or pair this when purchasing with our recommend RP-1200.1D 1,200 watt amplifier) The vented, single chamber, up-firing design of this enclosure allows the subwoofers to come alive, delivering tremoring bass while being responsive and dynamic across the entire low-end frequency spectrum. Finally, it is finished in a premium black trunk-liner carpeting allowing it to blend with your vehicles interior while also being visually stunning.
