This under-seat subwoofer enclosure is built specifically for the 4-seat Can-Am Defender MAX HD11 platform, mounting beneath the front seat and securing with just two bolts so cabin space stays open. It is not compatible with 2-door models. The box is resin-coated with a water-resistant finish to handle dust, moisture, and rugged trails, though it is not designed to be submerged.

Choose from four build levels: Level 1 and Level 2 each load four DD Audio 10-inch 500 series subwoofers (D2 or D4) for 2800 watts RMS and 8400 watts peak, wired for Dual-1Ω with 0.5Ω or 2Ω mono options. Level 2 with amps runs 1Ω at 900W per sub pair, and an optional 900W single-channel amplifier is available.
