Installation Instructions
Equipment:
Approved only for vehicles with option:
M490 - Sound package
The system can also be installed on vehicles with M680 - Digital Sound Processing (DSP). However, the extended sound adjustments with DSP can
no longer be made (The high performance amplifier does not have DSP inputs).
Information:
The High Performance Audio System is an exclusive, high-quality system calibrated to the vehicle, and offers increased performance (2 x 200 Watt
at 2 ohms), as compared to standard systems. The additional tuning allows for a rich and powerful bass in the lower ranges.
The HPAS is a 2-channel system with two mid-range loudspeakers in the dash and double bass loudspeakers in each door.
It is recommended to use at least an 80 Ah battery with the High Performance Audio System.

Note:
In order to ensure optimum sound, all radio settings (bass, pitch, loudness, etc.) should be set to zero, or neutral.
Diagnosis:
Four light-emitting diodes are located on the amplifier which can be used for diagnosis. The table specifies the position of the diodes from top to
bottom, colors, designations, functions and possible fault sources.

2.3.3 Route the wire through the hole in the carpet and the grommet in the firewall. Install the grommet with the wires into the firewall. Fix
wires to the firewall using a tie-wrap or adhesive tape. Seal the wire passage (Figure 3, Item B) with adhesive sealer, part number, 999
915 400 40 on the battery side.
2.3.4 Wrap the support bar with 50 mm of adhesive tape as shown (Figure 4).
2.3.5 Partially assemble fuse holder and connect the side with the red positive lead 6.0sq, to the positive terminal of the battery.
2.3.6 Trim the positive lead 6.0sq; color: red, of the wiring harness to the fuse holder and secure in the gold-plated bushing (second half of
the fuse holder) with the hexagon socket head bolt.
2.3.7 Screw the fuse holder together and use a tie-wrap to fit it onto the support bar that was wrapped with adhesive tape in step 2.3.4
(Figure 4).
2.3.8 Crimp the cable lug A6 to the ground lead 6.0sq, color: black, and secure the ground lead to the firewall at the ground point beside the
battery.
3. Rework the door panels and prepare for installation.

3.3 Trim the door panel along the mark with jig saw. Then deburr the cut edge with a file.
3.4 Put door trim panel (without loudspeaker) onto the inside of the door and check trim. There must be sufficient space for both bass
loudspeakers, 160 mm.
3.5 Make a hole for the fastening clip in the small insulating mat, as shown in Figure 6, Item A.
DANGER!
Danger (death/serious injury to driver or passenger) in the case of incorrect deployment of the side airbag.
>For vehicles with side airbags, the cut-out for the side airbag (Figure 6, Item B) must be removed before sticking on the large insulation mat.
3.6 Only vehicles with side airbag: Stick supplied insulation mats onto the inner side of each door panel (Figure 6). They are marked left
