Yeah they're going to have to design and tune parts of the car. Honestly it doesn't seem great; seems more likely to rattle and have weird characteristics at different volumes.

I will say, however, than the 'speakers' on the surface pro are kind of crazy. Pretty much all portable devices these days use the device itself to resonate. Not sure who the first one to do it was, but I'm honestly kind of a shocked at how good the sound is on that device, when it's being driven by these little things.
