I believe the Bose system in the Volt is different than what you would experience in other cars because the Bose in the Volt is specifically designed to draw less power, to conserve energy. The output will be less and therefore sound won't be the same. I'm not an audiophile so not a good judge, for me the Bose in the Volt sounds pretty good, certainly good enough.The Gen II Volt Bose setup is 'ok' subjectively, but when I drive my 2010 Infiniti, also equipped with a Bose system, the sound is noticeably better. I'm making that judgement when listening to SiriusXM. I'm not disappointed in the Volt Bose, but there are certainly better designs out there!
