I just replaced my rear deck speakers on my 2017 Scat Pack and after doing so, I have basically no FM reception or AM it appears either. I looked at the antenna connector at the top of the rear window and it was plugged in, even tried unplugging it and using a long piece of wire as an antenna and no difference. Is there a RF amplifier somewhere that I could have accidentally unplugged or something ? It looks like the coax travels the headliner and I didn't have any of that apart, only the rear deck area. Any ideas would be appreciated, thanks.
