ORIGINAL: BootCamp
From everything I've heard, nearly every "more agressive" system causes highway drone. Some guys are complaining of headaches after only an hour of highway driving with other systems. I'm not going to list system names since I think it's a matter of opinion and don't want to whizz on anyone's personal preferences.
You're right BootCamp, mine definitely does have a bit of a drone, but all things considered, I do like the sound.
