With this loaded enclosure, we eliminate the time spent on trying to figure out what subwoofers will work best with an empty enclosure, and offer you the best possible combination in one, easy to install solution. Designed to be a perfect OEM fit under the rear seat of the extended cab, this loaded enclosure gives you the ability to have exceptional bass in your truck without sacrificing any of the space that is already limited in these vehicles. The enclosure includes two of our well admired VD-12 D4 800-watt max power 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 when purchasing, pair this with our recommend RP-1200.1D 1,200 watt amplifier) The sealed, single chamber, down-firing design of this enclosure brings life to the subwoofers, providing elite bass while being responsive and dynamic across the entire low-end frequency spectrum. Finally, it is finished in a premium black trunk-liner carpeting which allows it to blend with your vehicles interior while providing an alluring appearance.
