What does everyone have their audio settings to?

I have the tech package and i'm trying to optimize my sound system but I don't know what I should have the Treble, center speaker, etc. at

 

I asked the same question a while back. It is really hard to get the optimum setting in this car, especially the different sources.
I have:-
Bass -2
Treble +3
Center +5
Fader -1(1 towards the rear)
Balance (Center)
Subwoof -2

 

This is what I have:

Bass +3
Treble +5
Center -2
Fader 0
Balance 0
Subwoof +6
Dolby ON

 

To me it's a matter of personal opinion; however, when Edmunds.com, tests car audio, the following is how the levels are adjusted:

How We Listen
When we critically evaluate an audio system, we listen to it under the following conditions:


•Sitting still with the engine at idle
•The volume set at moderately high levels
•All tone controls set to "flat" or at the center-detent position, including the fader and balance
•All surround or other signal processing turned off, if possible

While we also evaluate systems while driving and take into account road, wind and other noise and the overall quietness of the cabin, because of variables in road surfaces we test audio systems while sitting still to level the playing field. This also ensures that we give the listening task our full attention, without being distracted from the music while driving and vice versa. Likewise, when reviewing an audio system, we may comment on the presence and usefulness of the signal processing available, but for critical listening we switch it off.
