Our take on the Helix MS 8B-BMW.1

by Bob Bihlmayer

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Boom for your BMW

You love your BMW, but need more bass than the original 6-1/2" underseat subwoofers can give you. Or maybe want to install an amp, but the original speakers can't handle it? MATCH by Audiotec Fischer designed their MS 8B-BMW.1 8" subwoofers to fit in the original enclosures, and they'll fit into your budget as well.

More on the floor

Made in Germany, these subs feature special baskets which fit perfectly into the original BMW underseat enclosures without modification, so installation is pretty simple. They're built with fringe-field neodymium magnets and extra-large voice coils, so they they can handle up to 100 watts RMS each, and they use gold-plated screw terminals for better conductivity. Whether you're looking for more power handling or just more thump, the MATCH MS 8B-BMW.1's could be right up your strasse.

Features

Mounting: The MS 8B-BMW.1 fits as a direct replacement for the factory under-seat subwoofers in select BMW models. They are packaged as a pair, so you only need to purchase one set.

Wiring: The factory wiring does not plug directly into the new subwoofers. The factory speaker harness must be removed and the wires connected to the screw terminals on the MS 8B-BMW.1s.

Magnets: The MS 8B-BMW.1 subwoofers use neodymium magnets to minimize their size without giving up magnetic field strength.
