From the DSP training manual for BMW service techs:
Top-HiFi amplifier
With regard to its functionality, the Top-HiFi amplifier corresponds
to the previous DSP amplifier as already used in other
model series.
The special features on the E85 are the two high voltage output
stages (30 V) for the Carver woofers.
The Top-HiFi amplifier has 2 analogue inputs (left and right). In
addition, the Top-HiFi amplifier features a digital input for the CD
changer connection (coaxial cable). This arrangement achieves
a higher signal quality.
Front low-range speaker (woofer)
The woofer has a diameter of 160 mm and a paper cone. The
maximum load capacity is 50 W.
The woofers (low-range speakers) cover a frequency range from
50 Hz to 500 Hz.
Installation location
The front woofers (low-range speakers) are mounted at the
bottom in the A-pillars on the left and right.
Mid-range speaker
The mid-range speaker has a diameter of 100 mm and an
aluminium cone. The maximum load capacity is 50 W.
The mid-range speaker covers a frequency range from 100 Hz to
10,000 Hz. The front and rear mid-range speakers are identical.
Installation location
The front mid-range speakers are fitted in the doors.
The rear mid-range speakers are installed in the partition behind
the seats.
Top-HiFi audio system
The Top-HiFi audio system features a 10-channel analogue
amplifier with DSP technology as used in the current vehicles.
The Top-HiFi amplifier is controlled with a constant audio signal
via the two analogue output channels of the radio. In addition,
the Top-HiFi amplifier features a digital input for the CD changer.
The speakers are connected to the 10 output channels.
The Top-HiFi audio system has following output ratings:
- Medium-range and high-range speakers: 6x20 W
-
Low-range speakers: 2x40 W
- Carver low-range speakers: 2x100 W
