How many speakers does the 135i premium sound system have and where are they? I can find 6 speakers and the subwoofers under the front seats. Are there any others? The instructions in the manual are very difficult to follow.
I actually had that from an early press release from Harman/Kardon when they announced they were supplying the premium system for the 1 Series. They probably have the same thing for the other models they have supplied. You can check at either www.harmankardon.com or www.harman.com.
