Earthquake Sound Corporation is the original inventor of the Shallow Woofer System (SWS) that produces a lot of bass from a small space.
Designed to replace the BMW factory speakers that are located under the front seats, the SWS-8X requires no modification. Simply remove the seats and replace the factory woofers with the exact-fitting SWS-8X woofers to improve the sound quality of your mobile audio.
