Match UP W8MB-S4.3 LHD

Match UP W8MB-S4.3 LHD – 8″ upgrade subwoofers for the Mercedes C-Class 206 (left-hand drive)

The UP W8MB-S4.3 LHD is the version of Audiotec Fischer’s MATCH UPGRADE 8″ subwoofer developed for the Mercedes C-Class 206 generation (Convertible, Coupe, Sedan and T-Model from 2021). The set contains two 200 mm heavy-duty woofers that replace the factory bulkhead woofers in left-hand-drive vehicles.

Its key technology is an aperiodically damped speaker basket designed for deep and precise bass. The woofers fit the original bulkhead mounting positions, use a basket developed exclusively for Mercedes and car-specific connectors, and are tuned for the highest sound quality in Mercedes vehicles. They reach their full dynamic potential with an Audiotec Fischer DSP amplifier.
