Like it says when I turn the headlights on hte radio cuts off. I just got this car and there was no radio in it and the plug for hte radio was cut. So i just ran speaker wire to all the speakers from the new stereo and a constant 12V to the battery and the accessory I found with my multimeter that originally want to the factory radio plug. When I check with my multimeter the accessory power wire looses its power when I turn the headlights on. Also I noticed after I first hooked it up and my kids was playing in the car the stereo would turn ON when you turn on hte headlights with out the key even being in it. Now its the opposite lol so idk wtf to do or where to start looking. Im thinking a relay? Any help would be great and soprry bout the long post
