SUB-WOOFER
The dual voice coil sub-woofer speaker is located in the rear right side of the luggage compartment. A single 4 pin connector, connects the subwoofer to the vehicle wiring harness. The low-frequency bass sound from the sub-woofer complements the higher frequency sounds from the other system speakers.
The sub-woofer is powered by the AAM.
Operation
INCONTROL TOUCH 6 SPEAKER SYSTEM
The InControl System uses an Audio Head Unit (AHU) which contains an integral audio amplifier. The speakers are connected directly to the AHU for this system.
Audio signal originate from the AHU and are passed to the vehicle speakers via hardwired connections. Audio signals can also be generated by other vehicle systems which are passed to the AHU on the Medium speed Controller Area Network (CAN) comfort systems bus. The AHU processes the signals and passes the audio output to the speakers.
The AHU receives a fused power supply from the Battery Junction Box (BJB), via the Quiescent Current Control Module (QCCM).
INCONTROL TOUCH 10 AND 11 SPEAKER SYSTEMS
The InControl Touch 10 speaker and InControl Touch 11 speaker systems use an external Audio Amplifier Module (AAM). The speakers for these systems are connected directly to the AAM.
Audio signals originate from the AHU and are passed to the AAM via a medium speed CAN infotainment bus system. The speakers are connected directly to the AAM.
Audio signals can also be generated by other vehicle systems. The AHU processes the signals and passes the output to the AAM via the medium speed CAN infotainment systems bus and hardwired connections.
The AHU receives a fused power supply from the BJB, via the QCCM. The AAM receives a permanent fused power supply from the Rear Junction Box (RJB).
INCONTROL TOUCH PLUS SYSTEM AND INCONTROL TOUCH PLUS WITH MERIDIAN SURROUND SYSTEMS
The InControl Touch Plus System and the InControl Touch Plus with Meridian Surround Systems use an external Audio Amplifier Module (AAM). The speakers for these systems are connected directly to the AAM.
Audio signals originate from the IAM and are passed to the AAM on the Media Oriented System Transport (MOST) ring. Audio signals processed by other infotainment systems are passed to the AAM on the MOST.
Audio signals from systems not on the MOST ring, are passed to the AAM via the Gateway Module (GWM) on the medium speed CAN comfort systems bus to the Touch screen (TS). The TS then processes the signals and passes them to the AAM on the MOST ring.
The Integrated Audio Module (IAM) receives a fused power supply from the BJB via the QCCM. The AAM receives a permanent fused power supply from the BJB and RJB and a second power supply from the QCCM.
