Audio Module (AUD) (2003-2006): Design: Loudspeakers
Two pairs of loudspeakers and one center loudspeaker can be installed in the car.
The two pairs of loudspeakers are:
- front loudspeakers in the front doors
- rear loudspeakers in the rear doors.
The center loudspeaker is positioned in the middle of the dashboard.
In some versions of the audio module (AUD), a treble speaker can be connected to the front and rear speakers. The treble speakers for the front loudspeakers are positioned in the front door at the same height as the door mirrors. For the rear loudspeakers, the treble speakers are positioned in the D-post.
The three audio module (AUD) versions have different loudspeaker arrangements:
Performance
- one pair of front bass speakers
- one pair of rear loudspeakers.
Each loudspeaker consists of a transducer for the entire frequency range. There are no treble speakers connected to this version.
High Performance
- a pair of front bass / mid-range loudspeakers with treble speakers
- a rear pair of loudspeakers (coaxial*) with treble speakers.
The front treble speakers are electrically connected to the same signal cable as the front loudspeakers. The rear treble speakers are electrically connected to the rear loudspeakers.
Premium Sound
- a front pair of 3-way loudspeakers (consisting of a pair of 2-way loudspeakers with treble speakers)
- a rear pair of loudspeakers (coaxial*) with treble speakers.
- a centrally-mounted loudspeaker in the dashboard.
The front treble speakers are electrically connected to the same signal cable as the front loudspeakers. The rear treble speakers are electrically connected to the rear loudspeakers.
*Consists of one bass and one treble transducer integrated in the same unit.
