has anyone had trouble with the ignition wire and constant 12v wire, turning on the radio? mine wont turn on unless i hook up both yellow and both red wires but then the it wont go off when the car is off? any suggestions?

 

If it doesn't go off it's because you don't have the signal wire hooked up right to tell it to turn off.

 

Your ignition wire is red and your constant is yellow. Match them both up. They should be the same in the car as well.
