BOSE sound system
The new Audi A6 ´05 comes with a BOSE sound
system, which mainly comprises components from
the current Audi A8 ‘03. The division of the
subwoofer function into two individual subwoofers
integrated into the front doors means that the
well-known 7-channel DSP BOSE amplifier must
provide an additional output for the second
subwoofer driver in the front right-hand door. The
line-out output of the amplifier is used for this
purpose. This output signal feeds an external 100-
watt driver, which is integrated into the subwoofer
in the front right-hand door.
The current BOSE amplifier is replaced by a new
development with the launch of the Avant.
All eight drivers for the BOSE sound system are
then integrated into this new Avant amplifier.
Given this, it will be important to note the exact part
numbers and the related model year when replacing
components of the BOSE sound system in the
future, so that the functionality of the BOSE sound
system is not lost!
BOSE sound system diagnosis
Diagnosis of the BOSE sound system is also
performed using the address word 47 in the
VAS tester.
A basic setting is not required.
The available actuator tests can be performed either
selectively or sequentially.
The AudioPilot microphone, which is integrated into
the BOSE sound system, can be used to absorb
the acoustic pressure produced during the
loudspeaker actuator tests and output this on the
VAS diagnosis tester as a voltage signal.
If a voice operating system is installed, the
microphone for this is also included in the test.
The technician must then compare this voltage
reading with a default reading set at the factory and
evaluate the completed test as either OK or Not OK.
