    Product details

    GRS B200-2 ASD Series 8" Glass Fiber Subwoofer Speaker Pair Upgrade Kit for Select BMW Models 2 Ohms

     

    With a pincushion frame, shallow mounting depth, and front side wiring connection, BMW factory under/behind seat subwoofer drivers are extremely difficult to replace without extensive modifications. Designed to fit perfectly into BWM stock locations, the GRS B200-2 8" low profile subwoofer takes all the work out of replacing these unique drivers making these the perfect drop in upgrades for late model BMW vehicles.

     

    More than just a replacement, the no compromise design of the B200-2 is a significant improvement over the stock 2 ohm BMW driver. With a fiberglass cone and thick rubber surround, this driver will withstand the harsh conditions found in the automotive environment. The 2" voice coil can handle ample power and provides excellent control and linearity. Driving the voice coil is a large front mounted neodymium motor with extensive venting through the pole piece and voice coil gap, which provides sufficient heat dissipation with minimal air turbulence for quiet operation. Holding everything together is a rigid 2-piece steel and polymer frame that has been made specifically to fit the non-standard BMW openings.

     

    Note: Sold in pairs.
