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.\u003c\/p\u003e\n\u003cp\u003eFurthermore, 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 \u0026amp; Play amplifiers.\u003c\/p\u003e\n\u003cp\u003eNo 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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecial features:\u003c\/strong\u003e\u003cbr\u003eSwitch it parallel\u003cbr\u003eThe speaker connector with its gold-plated screw terminals allows two different configurations.
