I have a 2019 Expedition XLT non BO with 9 speaker sound system and a 2020 XLT with non BO sound system. I know the 2019 has 9 speakers (additional dash and a pair of tweeters in the front pillars), but does anyone know if the front pillars on the 2020 even have wiring for the tweeters? I would hate to fish wire to the pillars to install tweeters there, but if wires are there I could tap into them for my after market amp. I could install into the sail panel but really hate to do that either, especially since the cut-outs exist in the pillars already. Thanks in advance
