Description
Description
This under-seat subwoofer enclosure is purpose-built for the 2026 Can-Am Defender MAX HD11, nesting cleanly beneath the front seat of the 4-seat model to add deep bass without giving up cabin space. It comes loaded with two DD Audio 10-inch 500 series D4 subwoofers rated at 1,400 watts RMS and 4,200 watts peak, wired for dual-4Ω. The black textured enclosure mounts under the front seat and locks in with just two bolts, and its resin-coated, water-resistant build is made to handle dust, moisture, and rough terrain. Note that it is not compatible with HD7–HD10 or 2-door models.
