No one seemed to know that the Rear Speakers and Front A-Pillar Tweeters are run from the dash of the 2021 F150 Raptor. I did not know this until I was in middle of install and NavTV reached out to Don @SoundsGoodStereo since they purchase the most NavTV's. Luckily they were doing a Raptor install as well, and they had a solution. He was kind enough to get it to me ASAP (and Don did) so I could finish my install. Also had issues pulling radio out (12" display) and called them. After some back and forth someone in his crew called me back (9pm at night) and walked me thru. I did not have to pull the radio, this can be done from the top of the dash by pulling out the brains of the receiver and not the screen (2 separate parts which I did not know). In any case ran wires from there to behind glove box and along the sill to the back of truck to my setup. I can not thank them enough.
