However, if the negative input to the radio is to chassis ground you'll 
have a problem unless you float everything for DC.

Keep in mind that if you use standard silicon diodes, you're going to 
loose about 1.2 volts in the diodes, one on each side of the bridge, a 
pretty big hit in a 6-volt system.  Schottky diodes would be better by a 
factor of about two.
