Why not a voltage regulator or better yet - a 12V DC to 6V DC switcher.
There are lots of power supplies like this about the size of a hand

Might be a radio noise issue with an AM radio. Some of the "simple
switcher" chips are very easy to use, though. I've built little
switchers by epoxying parts on the back of a wallwart -- no circuit
board at all, just haywire things and then glop 'em good.
AM radio???
Certainly a switching supply would be more efficient than a linear.
It would. Don't know if it matters here or not. It's easy to sink a
few watts in a car.
