I full heartedly disagree there. If that were the case then why when the bass drops out, you can actually lower the volume a notch and the bass comes back for a bit?
Sorry, let me clarify. I said that in regards to bass seeming quieter or louder when the car's moving or not. I wasn't referring to the bass cutout problem above certain volume settings on the 08.5 ms3. I have an 07 so I don't have any experience with that.
