So from our experience the sound quality on the Bose system is ok. This is my wife's vehicle and she likes listening to classic and hard rock at relatively loud volumes. We have been a Dodge family up to this CX-5 and the Infinity system in both her old '09 Dodge Journey and my '12 Jeep Wrangler is far better. The Bose system is just not very loud, it is very clear, but it is just lacking in the frequency response. It sounds somewhat shallow and harsh where the Infinity systems in our other vehicles are just more full sounding. We are still playing with the setting to optimize the sound, but that cannot make up for the reduced volume.
