I cannot get any sound to come out of my Atoto7 double din. I feel like I have all the wires hooked up correctly except for the amplifier. The atoto has 2 blue wires that come out of it. one says power amplifier, the other says power antenna. I poked around the small yellow connector to see if I could get audio to play but got nothing. Any help would be appreciated. I tried to change the title but couldnt. I somehow fat fisted the keyboard and it submited the post sans edits and pics
