I disagree, kinda...

I played with the settings and when I went back into the stereo in normal mode, my changes had affected the regular settings. For isntance, before I played with the numbers, I had everything set to neutral.

After goofing around with the numbers, my balance was set to the paseenger side, the fade was higher in the rear, and the bass was cranked all the way up...

This is where I have ot step back and go "huh,?"
I picked some random number like 7374 8833 And that's what happened.

So like, i'm not 100% sure what I did, but I know that it did have a very definite effect :)
