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.

Have You checked the earth on the body that its not loose
Plus remove ALL pant where the earth conects to the body
Use a BOLT and NUT not a screw
This is common on old installs
If not Give me a call 0430033821 Australia
