MATCH MW 8BMW-D 400W 8” 200mm Under-Seat Shallow Subwoofer System for BMW Vehicles

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. If the metal bracket is mounted the woofer has an impedance of 1 x 4 Ohms - without the metal bracket each voice coil can be driven separately (in this case 2 x 2 Ohms) which is perfect for the 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.

Features:

• 8” / 200 mm subwoofers with very low mounting depth for shallow subwoofer designs and under-seat installation in BMW vehicles
• Allows to use extremely compact, sealed enclosures
• Oversized 42.5 mm / 1.7” voice coil for high power handling
• 2 x 2 Ohms impedance per woofer for most flexible connection options
• Plug & Play connectors for original BMW cable harness are included in delivery
• Fit directly into the original mounting positions under the front seats of all BMW model ranges with under-seat subwoofers
• Also, well suited for universal use in shallow subwoofer designs
