Match MW 8BMW-D

The MW 8BMW-D subwoofers are not only the ideal upgrade for those who are dissatisfied with the bass response in their BMW, but particularly for those who want to realize unprecedented space saving installation concepts.

The BMW-specific baskets and Plug & Play connectors allow a fast and easy installation into the original mounting positions of all BMW model ranges with under-seat subwoofers.

Nevertheless, these subwoofers are also perfectly qualified for universal applications. Thanks to the very low mounting depth, extremely compact sealed enclosures are no problem at all whereas the oversized 1.7” / 42.5 mm voice coil assures high power handling. Furthermore, the special speaker connector with its gold-plated screw terminals allows two different configurations and therefore flexible connection options. With the ex works installed connection bracket the subwoofer has an impedance of 1 x 4 Ohms, otherwise each voice coil can be driven individually (impedance 2 x 2 Ohms) and allows perfect combination with MATCH Plug & Play amplifiers.

No matter if these subwoofers are used as bass upgrade in your BMW or as problem-solver in small sub enclosures, they will definitely add loads of powerful bass for musical enjoyment.

This speaker is suitable to use in BMW Top HiFi ( Harman/Kardon, Logic7, Hifi System Professional DSP etc ) systems with codes S688A/S677A/S752A thanks to 4 Ohm load. You can get 4 Ohm load by connecting voice coils in series.
