Match UP W8MB-S4 RHD – 8″ upgrade subwoofers for Mercedes vehicles (right-hand drive)
The UP W8MB-S4 RHD is the right-hand-drive version of Audiotec Fischer’s MATCH UPGRADE 8″ subwoofer set for Mercedes. The two 200 mm heavy-duty woofers replace the factory bulkhead woofers in RHD C-Class (205), E-Class (238/213), GLC (253) and S-Class (W222) models and provide the deep, punchy bass the standard speakers lack.
The woofers fit the original bulkhead mounting positions, use exclusively developed baskets and car-specific connectors, and are tuned for Mercedes vehicles with significantly increased power handling. Audiotec Fischer states that they unfold their full dynamic potential with one of its DSP amplifiers.
