AM Stereo was doomed by the FCC and the industry itself as to which method of stereo encoding/decoding was to be used. There were a bunch of systems, Harris, Magnavox, and Motorola were three different ones that were at least compatible with each other, and another by Kahn-Hazeltine, which was incompatible with the other three.
The FCC was "unable" to determine a winner and allowed the marketplace to pick the best of the lot. Broadcasters lined up on both sides, with some favoring the Motorola group, while other big groups aligned with Kahn-Hazeltine. And no winner was ever decided by the marketplace.
I used to have a Nissan Maxima in 1989 that had an AM stereo receiver in it. It sounded great because it allowed the AM side to use a wide-band method of reception, which allowed for a fuller frequency response in the audio. Essentially, it sounded a lot like FM.
And being the radio geek that I am (or was), I bought, and still own a Sony SRF-A100 radio that picks up all kinds of AM stereo as well as FM stereo, of course. It has a switch on the side that determines the mode of AM stereo that you wish to receive.
Those are quite sought after, and hard to find.
