You didn't find the type of enclosure sub you are looking for? - If none of the four MATCH enclosure subs fits in your car with respect to shape and/or size, then you have the chance to build your "personalized" version by yourself. Therefore we offer the woofers PP 72W-D and PP 8W-Q, which are 100% identical to the drivers that are used in the pre-loaded variants. As long as you choose the net volume and port tuning frequency according to the installation instructions, we guarantee the same acoustical performance as our "standard" subwoofers.
