Most Mercedes-Benz E-Class W211 comes with fiber optic amplifier in the trunk, please note the new Android head unit does not support fiber optic amp, so you need to use a long cable B5 connect speakers directly in the trunk. You can check the plug behind the factory radio so that you can know if there are fiber optic cables there, the above picture shows the fiber optic cables so this car has fiber optic amplifier.

If your car does not have fiber optic amp, you just need to use one of the short power cables as below:
