Car radios (at least back in the tube era) were generally superior
to most inexpensive home radios. They included a tuned RF
stage which gave them the extra ooomph. The tube auto radios
had the antenna as part of the tuned circuit (coupled to the
high impedance point of the RF stage), so they worked somewhat
like a tuned active antenna.

Another reason was the lower IF -- generally 265 kHz vs. the 455 kHz used in
home sets. This allowed a more selective IF -- smaller bandwidth for the same
Q -- so the adjacent channel interference was cut dow. Some MW [BCB] DXers
would use car radios set up for home use for just that reason.

as compared to my home radios/stereos?
All--
Have wondered for years why this is so--almost w/o exception,
on both AM/FM. On the car NGs, it was suggested that my house was
blocking
signals, and that the metallic car acted as a big antenna. Neither seems
plausible, as my car next to the shop radio (which is terrible) still gets
good reception, and that if the metal in a car were so good, you wouldn't
need a car antenna.
I'm thinking it's the actual electronics. Any
opinions/explanations?
