Need help installing aftermarket car deck on my e39 plz
Just bought an alpine 133bt from crutchfield with the wire harness adapter.
I removed the stock head unit and disconnected the wires.
Soldered/crimped the wire harness to the car deck adapter.
Turned it on but no sound except staticy noises ( The noise you hear when you are flickering tv channels)
Did I miss a step?
The speakers are still stock if that helps.
