2. Disassembly of the back part of the original tray
The front part of the tray stays original on the door card. Only the
back part of the tray is cut off.
Drill only the rear plastic bolts,
which are originally welded with
the door card, on the back side of
the door lining (see g. a-f). Use a
6mm drill. These mounting holes
are used later on for the fastening
of the doorboard.
Cut off the carpet on the front part of the tray ➀ (1 cm is overlapping) the
normal cutting edge ➁ (see g. below) and pull away the tray a little bit.
Separate the tray on its smallest point in a way that the doorboard is
directly under the arm rest and in line with the front part of the tray.
In order to check the cutting edge place the doorboard on the door card.
Cut off the tray with a metal saw on the cutting edge ➁.

6 fastening points of the original tray.
Reference line: The front side edge of the doorboard is ush with the
cutting edge of the front part of the original tray.

7. Installation of the door lining onto car door
7.1. Fit the door lining in contrary order (described on page 3).
7.2. Cut out the foamed foil like a U (behind the woofers) in order to
improve the acoustic link to the door volume.
1. use the precisely aligned as pattern for the positioning of fastening points 1- 4
•marking of fixing points 1- 4:
mark with a thin awl on the door lining and set the holes according to
the marks set before. Use a 6mm drill.
2. mark speaker cut outs on the door lining. Take away the door-build. Cut out the
speakers’ outlines (see fig.) by means of a compass saw.
Do not cut out the foamed - it will be done after the installation of the door
lining. (s.page 9)
Tip for later retrofit back to original ( see fig.:)
Measure the cut out in size and volume that the speaker have
a good coupling to the door volume and also have enough bearing
surface for a leather covered carton grill, which may recover the cut-outs
(in case you like to retrofit back to original).
4. Handling of door lining / installation of the door panel
3. screw in the screws (1-4 M4x50). Affix the panel with all M4 screws through
the door lining exactly into the original fastening points. Secure with washers
and nuts. Screw only hand tight (screws 1-4), as there is no definitive point of end.
Check again for precise fit, tighten all screws and secure with adhesive or
safety paint.
All cutting edges of the panel must fit to the door lining snugly
all around without gap.
check all screw connections:
in order to avoid damages to the car door check the length of the staybolts
on the back side of the door lining once again and possibly shorten them.
This does not affect the ventilation.

7. Installation of the door lining onto car door
7.1. Fit the door lining in contrary order (described on page 3).
7.2. Cut out the foamed foil like a U (behind the woofers) in order to
improve the acoustic link to the door volume.
1. use the precisely aligned as pattern for the positioning of fastening points 1- 4
•marking of fixing points 1- 4:
mark with a thin awl on the door lining and set the holes according to
the marks set before. Use a 6mm drill.
2. mark speaker cut outs on the door lining. Take away the door-build. Cut out the
speakers’ outlines (see fig.) by means of a compass saw.
Do not cut out the foamed - it will be done after the installation of the door
lining. (s.page 9)
Tip for later retrofit back to original ( see fig.:)
Measure the cut out in size and volume that the speaker have
a good coupling to the door volume and also have enough bearing
surface for a leather covered carton grill, which may recover the cut-outs
(in case you like to retrofit back to original).
4. Handling of door lining / installation of the door panel
3. screw in the screws (1-4 M4x50). Affix the panel with all M4 screws through
the door lining exactly into the original fastening points. Secure with washers
and nuts. Screw only hand tight (screws 1-4), as there is no definitive point of end.
Check again for precise fit, tighten all screws and secure with adhesive or
safety paint.
All cutting edges of the panel must fit to the door lining snugly
all around without gap.
check all screw connections:
in order to avoid damages to the car door check the length of the staybolts
on the back side of the door lining once again and possibly shorten them.
This does not affect the ventilation.

mit einem dünnen Vorstecher auf der Türverkleidung markieren und die
Bohrungen gemäß Markierung mit einem 6 mm-Bohrer vornehmen:
2. Alle Lautsprecheröffnungen auf der Türverkleidung anzeichnen.
Paneel wieder abnehmen. Ausschnitt für die Lautsprecheröffnungen (S.Abb.)
auf der Türverkleidung mit einer Stichsäge vornehmen. Die Schaumfolie
nicht ausschneiden - diese wird erst nach der Montage der Türverkleidung
(s.Seite 9) u-förmig eingeschnitten.
�
Endkontrolle nach Türpaneel-Montage:
Alle Funktionen der Bedienelemente wie Sitzverstellung,
Handschuhfachöffnung, Fensterheber etc. überprüfen.
4. Bearbeitung der Türverkleidung / Montage der Türpaneele
3. Schrauben (1-4: M4x 50) eindrehen. Türpaneel mit der Türverkleidung durch
»leichtes Festschrauben«aller M4-Schrauben fixieren. Alle Schrauben mit den

7. Installation of the door lining onto car door
7.1. Fit the door lining in contrary order (described on page 3).
7.2. Cut out the foamed foil like a U (behind the woofers) in order to
improve the acoustic link to the door volume.
1. use the precisely aligned as pattern for the positioning of fastening points 1- 4
•marking of fixing points 1- 4:
mark with a thin awl on the door lining and set the holes according to
the marks set before. Use a 6mm drill.
2. mark speaker cut outs on the door lining. Take away the door-build. Cut out the
speakers’ outlines (see fig.) by means of a compass saw.
Do not cut out the foamed - it will be done after the installation of the door
lining. (s.page 9)
Tip for later retrofit back to original ( see fig.:)
Measure the cut out in size and volume that the speaker have
a good coupling to the door volume and also have enough bearing
surface for a leather covered carton grill, which may recover the cut-outs
(in case you like to retrofit back to original).
4. Handling of door lining / installation of the door panel
3. screw in the screws (1-4 M4x50). Affix the panel with all M4 screws through
the door lining exactly into the original fastening points. Secure with washers
and nuts. Screw only hand tight (screws 1-4), as there is no definitive point of end.
Check again for precise fit, tighten all screws and secure with adhesive or
safety paint.
All cutting edges of the panel must fit to the door lining snugly
all around without gap.
check all screw connections:
in order to avoid damages to the car door check the length of the staybolts
on the back side of the door lining once again and possibly shorten them.
This does not affect the ventilation.
