The MW 8BMW-D subwoofers are not only the ideal bass boost for anyone dissatisfied with the low-frequency response in their BMW, but also especially for those seeking extremely space-saving installation solutions in their vehicle.
Thanks to the BMW-specific speaker baskets and plug-and-play connectors, quick and easy installation in the factory-provided mounting locations of all BMW model series with under-seat subwoofers is possible.
These subwoofers also offer ideal conditions for universal use. Their exceptionally shallow mounting depth allows for use in extremely compact, sealed enclosures. The oversized 42.5 mm voice coil guarantees high power handling. Furthermore, the special connection terminal with its gold-plated screw terminals allows for two different configurations, providing maximum connection flexibility. With the included metal jumper installed, the subwoofer has an impedance of 1 x 4 ohms. Without a bridge, each voice coil can be individually driven (impedance 2 x 2 ohms), thus enabling optimal connection to MATCH Plug & Play amplifiers. Whether as a bass boost in your BMW or as a low-frequency supplier in universal applications, nothing now stands in the way of enjoying music with the right amount of bass. Features: 200 mm subwoofer with a particularly shallow mounting depth for ultra-flat subwoofer designs and under-seat mounting in BMW vehicles. Suitable for use in extremely compact, sealed enclosures. Oversized 42.5 mm voice coil for enormous power handling. 2 x 2 ohm impedance per woofer for maximum connection flexibility. Plug & Play. Play connectors for original BMW wiring harness included
