My wifes '53 Belair has an after market "looks original" AM/FM/Cassette player with a seperate power amplifier. If the radio is on, even with the volume down, the speakers produce a noise almost like my '66 C20's 4 speed whine!

Where's the best place to filter out this ignition noise? I think she's got the stock plugs for a 235.
