@teky: not sure about music part, but would agree for being "Crazy" Look forward to your installation review, try to capture following things 1. Default wiring on door panel, kindly click all the corners of the door. 2. The internal part of the door plastics 3. Wiring of power connection from battery to AMP, specifically the location in firewell from where the wire is pushed inside the cabin. And finally a video giving some audio demonstrations, specifically checking out vibrations on door at various sound levels.
