How does an amplifier pick up AM radio?
Radio frequencies from AM stations get into audio amplifiers not only through the inputs, but also via the outputs. The speaker cabling can serve as an antenna to pick up radio signals. This is is coupled back to the output of the amplifier. But the amplifier has a negative feedback loop which feeds the output back to the input.
How to troubleshoot poor or no AM or FM radio reception?
If you have an amplifier connected, disconnect the amplifier power. If the AM reception now improves, the amplifier is the problem. There is not a fix for this other than lowering the GAIN feature on the amplifier, if applicable. Try resetting the car stereo. There could also be a poor ground connection.

A station having a low-powered transmitter can cause reception problems, as well as a station that is a distance from where you are and the signal loses stamina by the time it reaches you.
