@MadWillMy one is SB, I can't believe there would be two subs, they either don't work or are made of paper or something.
Should there be a specific option for sub in MMI settings menu?
I can see only bass, treble, fader/balance and some others but no sub adjustment.
It is not that I'm an audiophile or have high expectations of the standard sound system, I simply compared the standard Volvo's 6 Speaker system without sub to the *** - which is 10 speakers incl. sub, and Audi's one isn't as good as Volvo's.
I simply made a wrong assumption, thinking 10 speakers should be good enough, well...
more is not always better ;-)
