Match MW 8BMW-D

<p>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.<br><br>The BMW-specific baskets and Plug &amp; Play connectors allow a fast and easy installation into the original mounting positions of all BMW model ranges with under-seat subwoofers.<br><br>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 &amp; Play amplifiers.<br><br>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.<br><br>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.<br><br>1-series E81 3-door 2004 – 2011 Under-seat<br>E82 Coupe 2004 – 2011 Under-seat<br>E87 5-door 2004 – 2011 Under-seat<br>E88 Convertible 2004 – 2011 Under-seat<br>F20 5-door 2011 – Under-seat<br>F21 3-door 2011 – Under-seat<br><br>2-series F22 Coupe 2011 – Under-seat<br>F23 Convertible 2011 – Under-seat<br><br>3-series E90 Sedan 2005 – 2011 Under-seat<br>E91 Touring 2005 – 2011 Under-seat<br>E92 Coupe 2005 – 2011 Under-seat<br>E93 Convertible 2005 – 2011 Under-seat<br>F30 Sedan 2012 – Under-seat<br>F31 Touring 2012 – Under-seat<br>F34 Gran Turismo 2013 – Under-seat<br>F35 Sedan Long Version 2012 – Under-seat<br><br>4-series F32 Coupe 2014 – Under-seat<br>F33 Convertible 2014 -<br><br>5-series E60 Sedan 2003 – 2010 Under-seat<br>E61 Touring 2003 – 2010 Under-seat<br>F10 Sedan 2011 – Under-seat<br>F11 Touring 2011 – Under-seat<br><br>6-series F12 Convertible 2011 – Under-seat<br>F13 Coupe 2011 – Under-seat<br><br>7-series F01 Sedan 2008 – Under-seat<br><br>X1 E84 SUV 2009 – 2012 Under-seat<br><br>X3 E83 SUV 2003 – 2010 Under-seat<br>F25 SUV 2010 – Under-seat<br><br>X4 F26 SUV 2014 – Under-seat<br><br>X5 E70 SUV 2006 – 2013 Under-seat<br><br>X6 E71 SUV 2008 – Under-seat</p>Technical Data: Power RMS / max.
