3.1. Place the door lining on a plane surface.

3.2. Dismount the loudspeakers attached to the panel for transport protection. Retain the screws for later assembly.

3.3. Place the panel without loudspeakers and grill on the door lining and align it:

Reference points for fitting:

Only precise alignment of the panel with the door

lining warrants optimal fit.

1. Reference line 1: put lateral panel edge directly to the notch of the door lining

2. Reference line 2: align lateral pins of panel integrated tray to the original mount of the tray

3. Reference line 3:

the lower edge of the panel is parallel to the lower edge of the door lining.

marking of fixing points 1-9:

use a thin awl to set the marks on the door-lining

2. draw the speakers’ cut-outs onto the door-lining.

3. remove the panel again. cut out holes for loudspeakers along the marking with a compass saw (see fig.)

4. use a 6mm drill for the screws according to the marks set before

5.4. reinstall the moisture protection foil


9/16


6. insulation of the door lining

Important tip:

the use of 2x16mm mid-woofer /side may cause vibrations which lead to annoying rattle noises in the car door

some helpful tips: • use our self-adhesive insulation fleece (art.no.: 27000) or a foam material for the backside of the door lining (see fig. above) or

• stabilize the backside of the door lining by means of a special material

(Glass Fibre Filler or stiffening material)i mportant: keep the cut-outs for the door-airbags and speakers open

• affix the *backside of the inner door metal with self-adhesive asphalt mats (see fig. * )

• by knocking on the car door, vibrations caused by mechanic parts (e.g. Bowden pull wire etc. ) and wiring harness may be found out. Cover these parts with foamed material, felt or something like that

• cut off overlapping cable tie (rattle noise)

• adhere felt or foamed material under the original wiring harness

!

Important:

No insulation material behind - loudspeaker - door latch lever - (fig. A): drill a hole for the installation clip

8. Speaker connection

Insert subwoofer and midrange and connect all loudspeakers

to the crossover circuit (parallel-circuit):

Notice: You should check the polarity of all subwoofers before connecting them to the crossover circuit

with a 9 volt battery:

All subwoofers must move uniformly!

Wrong polarity of a subwoofer can totally equalize the bass sound!
