That would be years ago. At one time car radios (even SS car radios) had
output transformers.

And soon after tube radios were phased out for solid state it wasn't
uncommon to find a Delco with a single TO-3 package germanium output
transistor, no transformer, working into a 40 Ohm speaker. I don't
think I've ever encountered a solid state car radio with an output
transformer. Of course they usually had some pretty big choke coils.
