Radio/tape Cd Player problems of the 2019 Volkswagen Jetta

I have the 2019 Jetta sel premium that includes the beats audio system upgrade. The speakers rattle and sound blown starting at just below 50% volume. I am at the dealer and they are inspecting the issue. There are many complaints of this on public forums. It seems as if the stereo head unit is too powerful for the speakers or is improperly allocating power to the speakers instead of the subwoofer. It is definitely not right whatever the issue is. This occurs on fm radio, satellite radio or iphone apple music via carplay.

While either stationary or in motion, and no matter where the vehicle is, there is a pronounced rattling that comes from the front passenger side door, and occasionally from the driver's side as well, when the radio is turned up to an enjoyable volume. This is a potential safety hazard as it's a rather irritating phenomenon that distracts the driver while operating the vehicle. I suspect this rattling is due to a lack of sound deadening or other form of noise insulation inside the doors. This notion is further supported by considerable road noise caused by the apparent lack of sound insulation in the floors as well.

The person on the other end of a phone call made via cars bluetooth and carplay, will hear an echo of themselves. The dealership replaced the radio, but the issue remains.
