Nothing to do with those voltages they are all just fine.

I would pull the radio forward and check the plugs and fuse on the rear, you can turn it on with it pulled out, tapping the radio may make it go off and on again, this would be a poor soldered connection in the radio

A perfect battery has just over 12.5 volts and a perfect alternator gives out 13.8 volts
