I have a 2010 maxima s with the Bose audio system and my 4 door speakers work but my rear deck don't I checked the wires they look good nd checked the voltage at the speakers with the radio on and there is nothing at all when the radio is on there should be some kind of signal but nothing ...I have read one but where someone told them to take it to the dealer and have a code re applied cause they were locked out can anyone help me with this problem give me some advice I thick they worked the other day but now nothing not hearing any different sound or nothing the speakers aren't blown cause if they were the wires from the terminal to the cone would be fried nd they are still intact ...thanks guys for any opinions
