Description
Sold individually — one SMS Precision adapter per quantity ordered.
FITMENT WARNING — Audi A4 B7 standard-audio subwoofer: An installer reported that this mounting pattern did not fit an A4 B7 with a standard factory-audio subwoofer mount. Do not assume compatibility with that factory bracket; compare all mounting points and enclosure clearances before ordering. This is one specific installation report, not universal proof of other trims.
Audi A4 B5 / B6 / B7 OEM Subwoofer-to-165mm Speaker Adapter
This SMS Precision adapter uses Audi A4 B5 / B6 / B7 OEM-subwoofer mounting geometry (subject to factory-audio and mounting-pattern verification) and allows a compatible 165 mm / 6.5-inch-class replacement speaker to mount using the factory-side geometry.
This product is specifically for the OEM subwoofer location.
Before You Order
- Vehicle: Confirm the exact A4 generation and factory standard- versus premium-audio subwoofer bracket geometry. A B7 standard-audio installation has been reported as not fitting this design.
- Location: Factory OEM subwoofer position — not a rear-door adapter.
- Replacement driver: Confirm the exact 165 mm / 6.5-inch-class speaker dimensions.
- Clearance: Verify basket, magnet, terminals, wiring and available enclosure / trim depth.
Add to Cart stays locked until the required fitment confirmation is complete where the guided builder is used.
