Car Amp no power but wire has power

My car subwoofers stopped working about a month ago. I have that setup for at least 4 years, a sony Amp and 2 10" Infiniti reference subs. About a month ago, the Sony amp power led light didn't light up and of course the subs didn't work. I got a new amp and connect to the power wires and the new amp still won't turn on (led light didn't go on). I checked the power wire and it measured around 11.5 volt. I turned on the car and the remote wire also measured 11.5 volt. But if I connect all the power/ground/remote wires to the amp, the remote wire has 11.5 volt but the power wire will measure 0 volt. I tried 2 different amps and got the same problem. Any idea? Thx.

earth = common or ground. Where does the black ground wire from the amp(s) go ?
