As neat as that sounds, I wonder what will happen when the amplifier and/or speakers start to give up the ghost in 5-10 years. I associate the word "BMW" with "wiring issues" so I'm skeptical of any system that requires unflinching reliability for the life of the car.

The 2015 Mustang with the turbo 4 cylinder has a similar system but the functionality can't be deactivated or tweaked in any way. Can you imagine the frustration of listening to the acoustic meddling through a blown speaker that you can't disable? I had a Lincoln Mark VIII where the stock amplifier fried itself when I was on the highway. It blasted static with wildly varying pitch at full volume for 5 minutes before I could safely pull over and pull the fuse. It was literally maddening.
