With the first one I had power but no sound as well.

I had the same problem: Power and function but no sound. I needed to hook the power antenna lead from the stereo to the amp lead in the car. Once I did that it worked with no problems. When I was done, my connectors looked like that, with the one wire jumping from one block to the other. That's the power antenna/amp power lead. You need to run that in order to tell the amp to energize when the radio is turned on.
