Integrated Audio Module (IAM) (2012): Design: Loudspeakers
The integrated audio module (IAM) for Performance has six speakers directly connected to the control module:
In each front door there are two speakers. The 2-way system consists of broad-banded bass/mid-range speakers and separate treble speakers. In both rear doors there is a broad-banded bass/mid-range speaker.
The impedance is 2 Ω for the base/mid range loudspeakers and 5 Ω for the treble speakers.
For versions without an amplifier, the loudspeakers are connected to the Audio module (AUD).
