The SSV Works Can-Am Defender HD11 subwoofer enclosure is a 10-inch ported sub box for the front or rear passenger-side seat of 2026 Defender HD11 and MAX HD11 models. It uses factory mounting locations with no cutting or floor modification. It is an enclosure, not a powered kit: you supply the amplifier and wiring.
Order it as an enclosure only, or loaded with an SSV Works V10 10-inch 2-ohm subwoofer. Each order is one enclosure; add a second for the other passenger-side seat to build a dual Defender HD11 subwoofer setup.

Why SSV Works
SSV Works builds vehicle-specific off-road audio: speaker pods, subwoofer enclosures and complete systems designed to mount in factory locations and hold up to dust, water and vibration. Each SSV Works enclosure and pod is engineered for a specific machine or system, so you are not adapting generic car audio to fit.
