We don't know if your amplifier is turning on.

We don't know what is connected to the amplifier inputs.

Please post a picture of your head unit wiring.

I've done many head unit installs, and I wouldn't do one without a voltmeter. I wouldn't work on a BMW without a voltmeter.

The most common problem with head unit installs in BMWs is powering the wrong lead for amp turn on.

So are you retaining the head unit in the car?
