So my buddy came to me with a problem. When he starts his truck the deck turns on and plays normal. But when you pull the little lever to turn on the head lights, the speakers shut off but the deck continues to be on... Also if the truck is off, and you just pull the lever to turn on the lights, the deck turns on but again nothing from the speakers. He ran his own speaker wire, used the factory ground, his constant is straight off the battery and his turn on lead is from a random wire from in the dash that would be dead, then read 12 v when the key was turned to on position. Any ideas what might be up? Figured its best just to rewire it but still confused and why it acts as it does.
