tomcat66, on your sound system channel volumes on db5.1, increase center channel and rear channel volumes, also small increase on bass channel help(more for buttkicker).
Finding good balance between center and rear channels gives out real sounds of game, bass also can be used, I'm playing with 5.1 headset so not wanting too much bass directly to ears.
If tried to show GT6 balances are on default, it's close to this: (0= optimal volume)
Left & right channel = 0
Center channel = -2
Rear channel = -3
Bass channel = -2
So need to rise from those -2 and -3 values to zero, by adding more volume there.
