Sensational surround sound
Some 14 speakers and one amplifier create 505 watts of superb sound, balanced to suit the acoustic properties of the car’s interior.
A second digital signal-processing amplifier takes output from standard stereo sources such as CD players, iPods or DAB radios and creates stunning five-channel surround sound. The Bang & Olufsen sound system is standard on the A4 Black Edition and optional on all other models.
