Jaguar XK 2010 - Audio System - The audio system seems to no longer have any "Bass" through the sound system. I have adjusted the controls to full Bass, and reduced the Treble to zero, but it still sounds like there is no Bass coming from any of the speakers (Bowers & Wilkins), front or back. Is there a relay or fuse that would control the Bass sound? Or, is there something I should look at? Thanks.

 

The Subwoofer is in the passenger footwell, give that a listen.
