SWS Shallow Woofer Install
Our most popular size from the Shallow Woofer line is the SWS-8” due to the fact that it is designed to replace the BMW factory speakers that are located under the front seats. They are the best solution for replacing BMW subwoofers with hardly any modification required. Simply remove the seats and replace the factory woofers with the exact-fitting SWS-8 woofers to improve the sound quality of your mobile audio.
Earthquake Sound also produces the SWS-8Xi that has a 2Ω voice coil which is the same impedance as the BMW factory speakers.
In addition to BMW cars, the SWS series are used in many other applications where subwoofers are needed and space is limited, such as in car doors. Many car manufacturers are now using woofers in small areas. To improve your bass, simply replace the factory speakers with SWS woofers.
