Audi B8/B8.5 A4/S4 OEM+ 8" Subwoofer Adapter / Enclosure

Upgrade the bass in your B8/B8.5 Audi without giving up trunk space or the clean factory appearance.

This OEM+ 8" subwoofer enclosure was designed specifically for the Audi B8 and B8.5 A4, S4, and RS4 Sedan platform, utilizing the factory rear-deck subwoofer location for a clean, integrated installation. Rather than adding a bulky enclosure to the trunk, this solution keeps the subwoofer tucked neatly into the factory location while providing a proper enclosure for an upgraded shallow-mount 8" subwoofer.

The enclosure was designed around the 8" Kicker CompRT shallow-mount subwoofer, providing an excellent combination of output, depth, and fitment. Other shallow-mount 8" subwoofers may also be compatible; mounting dimensions and depth should be verified before ordering.

OEM+ Fitment

Each enclosure includes our OEM speaker connector adapter, allowing you to retain the factory-style electrical connection rather than cutting or splicing in to the vehicle's original speaker wiring.

The adapter can simply be press-fit into the integrated enclosure mount or permanently secured with adhesive if desired. The result is a clean, serviceable installation that looks and connects exactly like something Audi installed from the factory.

Built for the Automotive Environment

The enclosure is manufactured utlizing ASA filament, selected specifically for its increased heat, UV, and environmental resistance.

Subwoofer is not included.

For anyone looking to add considerably more low-end performance to their Audi while keeping the interior and trunk looking factory, this enclosure provides the kind of upgrade we like best: more performance, less evidence that anything was modified.
