The system has "speed-sensitive" volume control, and auto loudness. Unfortunately, GM radios also turn off the loudness automatically at higher volume levels so it's actually possible to get the volume to a point that only a slight increase in volume actually makes it quieter
BTW, are you aware that you CAN customize the EQ settings?

Do you have a service manual? If so, it's in there. If not, I can email the procedure to you naxt week once I go back to work (I'm on vacation).
