As you all know that the premium stereo doesn't sound that great so here is a little setting that I tried and sounds better.
For me the sound was coming in too strong in the front and not enough of the subwoofer was coming in, so I did a FAD adjustment. So the front is on the 3 setting not 5 and now I can hear the rear speakers and the subwoofer better, you can try the 2 setting if you need more rear speakers.
Try it........
