Just got a 2012 Ford Taurus and there's no sound coming out of the rear speakers. How do I fix that?

Cover it in petrol set it alight then claim on insurance, with the money you get buy a car with working rear speakers.

Have you tried the balance nob and the fade nob it may be set to just the front speakers.
