DESCRIPTION
All vehicles are equipped with Infinity speaker sys-
tems. The base system has seven speakers and a six
channel amplifier with maximum power output of
200W. The Intermezzo system has the same door and
instrument panel speakers as the base system plus a
dual voice coil (2 channel) subwoofer and a surround
sound amplifier with maximum power output of
385W. The amplifiers are powered by dual 12V feeds
from a single Integrated Power Module (IPM) fuse
and are energized by a combination of ignition line
status and PCI bus messaging from the radio.
OPERATION
The amplifiers receive right and left channel audio
inputs from the radio receiver. The base amplifier
sends audio outputs to five channels, the Intermezzo
outputs to seven channels. These amplifiers also
receive audio inputs from the navigation unit and
hands free phone module when so equipped.

begin with the use of the DRB III
t diagnostic
tool. For information on the use of the DRB

t, refer to the appropriate Diagnostic Service
