Frequently Asked Questions

What’s the difference between this and the HD10 enclosure?
The HD11 enclosure is a completely different design built specifically for the Defender HD11 cab geometry. It is not interchangeable with the HD10 driver or passenger enclosures.

Do I need a separate amplifier?
Yes — an amplifier is required and sold separately. We recommend any UTV Stereo Elite Series monoblock amplifier rated for your subwoofer’s power handling.
