Interference will not generate significant current in the cables, but for a sufficiently long run, it can generate measurable voltages at your amplifier output.

Interference will not generate significant current in the cables, but for a sufficiently long run, it can generate measurable voltages at your amplifier output. Depending on the power stage, this can cause your amplifier to react to the interference (e.g. if there is high-impedance negative feedback). With just the correct setup, a poorly designed power stage, and a long enough speaker cable run, you can pull in an AM station.

- rsaxvc 3y agoThis happens near loads of broadcast AM stations. https://www.reddit.com/r/audio/comments/rfmfkq/home_audio_speaker_cables_picking_up_radio/ https://www.reddit.com/r/audio/comments/rfmfkq/home_audio_sp...
