1. I think the sound quality will be "Good." I might go so far as to say great, because from mulitiple places, it's been whispered that there will be a 'new' audio system in there. (Brand diff from anything GM has used thus far.)
2. Can't say much about that, as I'm more interested in the sound from under the hood.:p
3. The
Cobalt comes standard with an AUX jack...so I'm pretty confident we'll see at least get that.
Unless it gets a new, unknown system - then it's a wild card.
