Can-Am Defender HD11 500W Single 10" Subwoofer Kit

Get into the Defender HD11 sub game with the 500W Single 10" Subwoofer Kit — the most accessible entry point in UTV Stereo’s HD11 lineup. This complete kit pairs a vehicle-specific vented passenger-side enclosure (front or rear) with a 500W M-Series monoblock amplifier and an IP65-rated 10" Elite Series subwoofer for clean, punchy bass without the complexity of source unit integration.

The 500W kit is designed for HD11 owners running an aftermarket head unit who want a straightforward, powerful single-sub upgrade at the best value price in the lineup.

Frequently Asked Questions

How does the 500W kit differ from the 1000W?
The 500W uses the M-Series monoblock amplifier and a Dual 1Ω subwoofer. The 1000W upgrades to the Signature Series monoblock and Dual 2Ω sub for more output headroom. Both use the same HD11-specific vented enclosures.

Does the 500W kit support BRP GO! integration?
No — the 500W kit pairs with an aftermarket head unit (sold separately). If you’re running the factory BRP GO! 10.25" screen and want plug-and-play integration, choose the 1000W or 1200W Single Sub Kit instead.

Do I need a second battery for this kit?
A 500W single-sub system runs comfortably on a healthy stock battery in most riding conditions. A 2nd battery kit is recommended if you frequently ride at low RPMs or plan to add additional amplified speakers later.
