Could a Sonos Move 2 be used as a standalone in-car speaker?

[wax lyrical]

For playing tracks off Apple Music, Spotify, etc? Anyone tried it?

Would probably be a much better sound than a lot of crappy car OEM music set-ups.

Yes it would work and lots of people do stick a bluetooth speaker in old/ vintage cars.

However, there would be no stereo separation and due to a cars acoustic environment, the bass that you might hear in your living room, is not going to be as good in the car, due to levels of road noise.
