Pretty much every radio station out there now except the local college stations sound absolutely terrible. It's like there's a gong or something lightly discernible in the background. It's more pronounced on some tuners than on others. My 2014 Wrangler's OEM stereo does the best at minimizing it, but even there I can hear it. It reminds me of low-bitrate MP3 artifacts from a file encoded in the late 90s. What gives? It's all my tuners, and it doesn't matter if I drive to Raleigh, I can still hear it on most radio stations, so it's not location dependent. Thoughts? Charles.
