So I have never used this before, using the radio speakers to broadcast police radio over them... I’m redoing a 2010 Charger and I kinda just want to try it. I know the 3 wire/pin connector is what it’s for but I’m kinda not wanting to make a mistake here. Do I hook left and right speaker into the 3.5 mm jack in the rear of the radio where a external speaker normally hooks in and then hook the “common” to my mic clip to silence the radio when my mic is picked up?? Thanks
