XC90 FWD L6-3.2L VIN 98 B6324S (2007)
The integrated audio module (IAM) is connected to an AM and FM antenna system. This consists of a main antenna, an FM sub-antenna and an AM
antenna. The antennas are connected to an antenna amplifier. The antenna amplifier has two channels: one for the FM main antenna and the AM antenna
and another for the FM sub-antenna.
Both channels are connected to the integrated audio module (IAM) via a coaxial cable.
The connection for the sub antenna is used to supply power to the antenna amplifier. If the Multimedia module (MMM) is in the vehicle (does not apply
to the USA), the sub antenna is connected from the antenna amplifier to the Integrated Audio Module (IAM) via the Multimedia module (MMM).
Remote control via a steering wheel keypad is available as either an option or as standard equipment depending on the market. The keypad is located on
the right side of the steering wheel and is connected to the steering wheel module (SWM) via serial communication.
The integrated audio module (IAM) for Performance has 4 speakers directly connected to the control module:
one pair of front loudspeakers
one pair of rear loudspeakers.
Impedance for each speaker is 4 ohms.
For the two other versions with the integrated audio module, the speakers are connected to the audio module (AUD).
