9.1. Precisely align and carefully press grill into the Velcro fasteners.
The Velcro fastener makes a crackling sound
when it is closed correctly.
9.1. Precisely align and carefully press grill into the Velcro fasteners.
The Velcro fastener makes a crackling sound
when it is closed correctly.
Removing the grills:
The Velcro fasteners stick together very strongly!
The grills can be removed anytime by carefully lifting them off.
Please, avoid any way of forceful yanking at the grills.
It could break!
9.3.
9.2. Our Tip:
If the panel cannot be pressed on completely at some points. . .
Cause: the special form at these points and the resulting differences in
material cross section of the grill.
Solution: the distance can be levelled out with spacers 3 under the
Velcro disc.
(Spacers included with the screw kit)
1. roll down the window completely
2. pull off the plastic caps from the door handle and remove the both
Torx Screws (A1 u. 2) underneath
3. carefully push the faceplate of the door latch lever (B) out of the catch
4. remove the switch of the rear-view mirror (driver’s side) and the grill
(co-passenger’s side) on the door handle (C) and disconnect the cable plugs
5. carefully squeeze the door panel away from the plastic clips at the lower
and lateral edges of the door lining
6. lift the door panel out of the sealing above and simultaneously move it
horizontally and forward away from the inner door metal
7. disconnect the original loudspeaker plugs

8. Crossover circuit - Speaker connection
8.1. precable crossovers - see fig. page 11.
8.2. install crossover in the back part of the door-lining (see fig. –possibly without
housing, covered with foamed material) –use a hot melt adhesive or 2 sheet
metal screws from the hardware bag
8.3. 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:
pole of the crossover circuit input to of a 9 Volt battery
pole of the crossover circuit input to of a 9 Volt battery
All subwoofers must move uniformly!

3 . Panel alignment
Reference points for fitting:
Only precise alignment of the panel with the door
lining warrants optimal fit.
Reference line 1: align “nose”on the panel directly into the notch of the
door lining. This results to a distance between upper edge of
the panel and lower edge of the original tweeter grill of 80 mm.
Reference line 2+3: realign the back edge of the panel to the edge of the door lining
with a distance of 13,5cm (see ref. point 2 above). Distance
of the front side edge 4,6cm (see ref.point 3 above)
Reference line 1: the lower edge of the panel is parallel to the edge of the door lining

7. installation of the door-lining onto the the car doors
7.1. put the door-lining into the upper sealing of the car door
7.2. fit it in contrary order of succession as described on page no. 3
7.3. cut out the moisture protection foil (u-form) and stabilize the lateral cutting
edges in order to avoid vibration noise ( e.g. use a packing tape)
1. use the precisely aligned panel as template in order to mark fastening points 1- 9:
• mark the fastening points 1-3_ premounted in the panel:
pressing the panel to the door lining leaves visible impressions of the screws
•mark the fastening points 4-8:
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 (see fig.)
with a compass saw.
4. use a 6mm drill for the screws according to the marks set before
5. Screw in the M4-screws supplied with. Affix the door build to the door-lining.
Screw all 9 x M4-screws only hand-tight .
Secure all screws with the washers and nuts.
6. check again for precise fitting and tighten screws.
All cutting edges of the panel must fit to the door lining snugly
all around without gap

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
