I've read here that the Harman Kardon sound system in the 3.6R Limited is awesome and also that it is pathetic. Sound quality is highly subjective, but still these extremes don't seem right. I'm really happy with the Bose system in my Corvette, and folks complain about Bose as well. They say it's a bit muddy and could use more power. How would you describe the Harman Kardon?
