Component sound

When it comes to vehicle-specific speakers, BMW owners have a nice selection to choose from, but MATCH by Audiotec Fischer stands out from the rest by offering a component system with significant power handling. If you've been intimidated by the idea of altering your BMW with aftermarket speakers, don't be. MATCH's installation is hassle-free, thanks to 4" woofers designed to fit the original mounting position in your doors and 1" silk dome tweeters made for direct-fit installation in your BMW's factory tweeter housing.

Match crossover

MATCH's high-end crossover provides a reference curve for easy setup.

German quality

What better for your German-engineered car than a German-engineered sound system? MATCH's handcrafted speaker design is precision-built using the latest technology and materials. To minimize distortion, the woofer uses a special magnet structure that efficiently dissipates heat and promotes extreme accuracy. The dome tweeter's coated silk construction brings a natural smoothness to the high frequencies.

Fine tuning

MATCH built the compact crossover with a frequency curve and filtering designed specifically for your BMW. MATCH has also given you plenty of leeway in the power department, as these components handle up to 60 watts RMS. You'll be knocked out by the sound of these speakers even if you're powering them with your original BMW radio, but they'll perform on a completely new level when powered by an outboard amp.

Installation note #1: To ensure that this direct-fit speaker system is compatible with your BMW, please enter your vehicle information or call an Advisor at 1-888-955-6000.

Product Research


Mounting: The midrange included with the MS 42C-BMW.1 system mounts easily in place of the factory midrange using the included thumb nuts. The included tweeters snap into the BMW factory tweeter housings.

Wiring: The system includes wire for the woofers, tweeters, and crossover inputs. The two 18" woofer wires have spade connectors on both ends (both the woofers and crossovers have screw terminals). The two 32" tweeter wires have spade connectors on the crossover end and bullet connectors on the tweeter end (the 10" wires attached to the tweeters also have bullet connectors attached). The two 20" crossover input wires have spade connectors on the crossover end and bullet connectors on the input end (these inputs must be spliced into the BMW factory wiring, they do not plug directly into the factory harness).

Crossovers: The crossovers are separate components with screw terminal inputs and outputs. The screw terminals will accept bare wire or spade connectors up to 1/4" wide. The included wire has spade connectors attached. The crossover dimensions are:

  • Width: 2-3/8"
  • Height: 1-3/16"
  • Depth: 3-5/16"
