The SSV Works Can-Am Defender HD10 subwoofer enclosure is a 10-inch ported sub box that mounts under the front or rear, driver or passenger seat of 2018-2025 Defender HD10 and MAX HD10 models. It uses factory mounting locations with no cutting, and you can run one to four of them. 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, so order one for each seat you want to fill for a dual or quad Defender HD10 subwoofer setup.
Key Features
- Ported Defender HD10 sub box with a 70mm x 275mm port
- Fits under the front or rear, driver or passenger seat
- Run a single sub or up to four (SSV's "single to quad" setup)
- Factory mounting locations, no cutting or modification
- High-strength rotomolded enclosure
- Enclosure only, or loaded with an SSV Works subwoofer: the V10 10-inch 2-ohm
Built To Solve: No Bass In A Can-Am Defender HD10 Cab
- A radio or sound bar alone has little low-end in an open cab
- Some subwoofer installs mean cutting or drilling the floor
- A universal UTV subwoofer box on the floor takes up cab space you use for work gear
Best For: Can-Am Defender HD10 Owners Adding A Defender Under-Seat Subwoofer

Fitment
SSV Works' compatibility chart lists 2-door Defender HD10 Base/DPS/XT (2018-2025), X MR (2018-2025) and Limited (2020-2025), and MAX HD10 Base/DPS/XT (2018-2025), X MR (2019-2025), Lone Star/Cab (2018-2025) and Limited (2020-2025). The same chart also checks 2026 Defender HD11 and MAX HD11 (all models), but SSV's dedicated HD11 version of this enclosure is listed for passenger-side seats only, so HD11 owners should confirm seat position with us before ordering. Fitment is not guaranteed on unlisted applications.
FAQ
Is the subwoofer included?
Only on the loaded variant, which includes an SSV Works V10 10-inch 2-ohm sub. The Enclosure Only variant has no subwoofer.
Does it come with an amplifier or wiring?
No. You need your own amplifier channel and wiring for each sub. This is an enclosure, not a powered plug-and-play kit.
Which seats can it go under?
SSV designed it to mount under the front or rear, driver or passenger seat of the Defender HD10, so you can run one enclosure or up to four. Each order is one enclosure.
Does it fit the 2026 Defender HD11?
SSV's chart for this enclosure checks 2026 HD11 models, but SSV's dedicated HD11 under-seat enclosure is listed for passenger-side seats only. Contact us to confirm before ordering for an HD11.
How does it install?
SSV says it uses factory mounting locations and installs without cutting or modification. Then wire the sub to your amplifier.
Should I order enclosure only or loaded?
Choose enclosure only if you already have a 10-inch sub that fits. Choose the loaded variant for SSV's matched V10 2-ohm sub, rated 500W RMS.
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.
Add Under-Seat Bass To Your Can-Am Defender HD10
Choose enclosure only or V10-loaded for your Can-Am Defender subwoofer, order one for each seat you want to fill, and confirm you have an amplifier channel and wiring for every sub. You can pair this enclosure with SSV's Defender rear-upper speaker pods or Kicker sound bar, but each sub still requires an amplifier and wiring, sold separately. Order from Dunes 2 Dezert SXS.
