UPGRADING FACTORY SUBS TO EARTHQUAKE SWS-8XI on my BMW F10 535i

I bought these Earthquake SWS-8XI used from a member on the forums. They replace the factory subwoofers that are under the front seats on most F-chassis BMW.

I have the S677 HiFi Professional DSP sound system. So although these Earthquakes were an upgrade from my subs, the improvement would be even more noticeable by someone with the base HiFi system (option S677).
