I have read many reviews about the Harman Kardon upgrade and many people said they were disappointed or not impressed...I am not sure if they changed something for 2011 but the system sounds amazing! I am comparing it to my fathers upgraded system in his E90 M3 which has a whopping 825 Watts! BE sure to watch the video in HD and turn it up.
(Please don't take offense to my video, I was hungover and was completely out of it)
