The SSV Works rear-seat ported 10-inch subwoofer enclosure drops in under the driver-side rear seat of 4-door 2024-2026 Polaris Xpedition XP 5 and ADV 5 models to add real low end. Order it as an enclosure only to run your own sub, or loaded with an SSV V10 10-inch subwoofer.
As a Polaris Xpedition subwoofer location, the rear seat keeps the enclosure out of sight and out of the cargo area. This Xpedition rear seat subwoofer box is a 10 inch ported subwoofer enclosure in high-strength rotomolded material, and it fits the Xpedition XP 5 subwoofer and Xpedition ADV 5 subwoofer applications SSV lists. It is the bass foundation for an Xpedition audio upgrade or Polaris Xpedition stereo build, not a complete system: you still need an amplifier channel and wiring to power it. Compared with a generic UTV under seat subwoofer box, this SSV Works subwoofer enclosure is an Xpedition sub enclosure shaped for the driver-side rear seat.

FAQ
Does it fit the 2-door Xpedition?
No. SSV Works lists this enclosure for 4-door Xpedition XP 5 and ADV 5 models only and marks 2-door models as not compatible.
Is the subwoofer included?
Only if you choose the SSV Works V10 2ohm Subwoofer option. The Enclosure Only option has no subwoofer, so you install your own 10-inch sub.
Does it include an amplifier or connect to Ride Command?
No amplifier or wiring is included, and SSV Works does not list Ride Command integration for this enclosure. You need an amplifier channel and wiring, sold separately, to power the subwoofer.
Which Xpedition trims are covered?
SSV lists 2024-2026 XP 5 NorthStar and ADV 5 NorthStar, plus 2024-2025 XP 5 Ultimate and ADV 5 Ultimate.
Why choose a ported enclosure?
SSV Works says the ported design increases low-frequency efficiency and output, for deeper bass with more impact.
How hard is it to install?
SSV describes it as a direct drop-in under the driver-side rear seat with no cutting, trimming or custom brackets. Bolt it in, then wire the subwoofer to your amplifier; SSV Works provides installation instructions.
Why SSV Works
SSV Works has built purpose-made UTV audio since 2006, engineering weatherproof speakers, enclosures and complete systems for the dust, water and vibration of off-road riding rather than adapting car or marine gear.
