AM/ FM Radio
WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
The AM/ FM (2016 MY) or AM/ FM1 (2017 MY+) roof-mounted antenna receives analog radio waves and sends them through the AM/ FM (2016 MY) or AM/ FM1 (2017 MY+) antenna coaxial cable to the ACM. For the 2017 MY+, the FM2 on-glass antenna grid receives analog radio waves and sends them through the FM2 diversity antenna amplifier and FM2 antenna coaxial cable to the ACM. The radio waves are converted into fluctuating AC voltage and sent as left and right analog audio signals to the subwoofer amplifier and all speakers except the subwoofer. The subwoofer amplifier processes the audio signals and sends them to the subwoofer speaker as fluctuating AC voltage.
