Unhooked everything in my truck, put it in my buddys truck and it worked perfect. Put it back into my truck, same problem. I have 12.24 volts from my power cables, and a good ground, I have 10.8 volts off my remote wire. What would cause it to go into protect mode? Could my deck possibly be bad? Or a bad remote wire even though i have 10.8 V back there???
