// Build your BASS stage

BUILD YOUR STAGE THE RIGHT WAY.

This ported 10" subwoofer enclosure is the foundation for real low-end in the HD11. Designed to fit cleanly under the front or rear passenger side seat, it delivers the kind of output and bass response you can actually feel, without sacrificing a factory-style look.

// INSTALL-READY DESIGN

SINGLE OR DUAL SUB SETUP.

The sub enclosure is designed for flexibility, mounting cleanly under either the front passenger seat, or the rear passenger seat, giving you the option to run a single or dual subwoofer setup. Using factory mounting locations, it installs without and cutting or modification, unlike other options on the market that require altering your floor. This means a clean, secure fit with an easy install that preserves your vehicle exactly as it should be.

// SIGNATURE LOW END

DEEP BASS, BUILT FOR ABUSE

Loaded with an SSV 10" subwoofer rated for up to 1000 watts max, with 85 dB sensitivity and a 40 Hz–1.5 kHz frequency response. Built for the UTV world, it’s designed to take real vibration and punishment while delivering tight, hard-hitting bass that keeps up at speed.

// PORTED ENCLOSURE DESIGN

TUNED FOR DEEPER BASS OUTPUT

The enclosure’s ported design is engineered to increase low-frequency efficiency and output, so you get deeper bass with more impact and less strain. More air movement, more authority, and a fuller bottom end that transforms the system.

// PLATFORM-SPECIFIC PERFORMANCE

ENGINEERED FOR THE HD11.

The HD11 with factory audio is lacking some serious bass. Our subwoofer add-on kit brings that missing link. With factory integration, all factory features still function as they should

// Warranty Coverage

Built to last, backed to prove it.

We back what we build with coverage no other powersports audio brands come close to. This enclosure and the SSV subwoofer are protected by our Limited Lifetime Warranty, so your bass upgrade is covered for the long haul.
