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 inmaterial cross section of the grill.

Solution: the distance can be levelled out with spacers 3 under theVelcro disc.(Spacers included with the screw kit)

1. roll down window completely

2. remove both plastic caps underneath the door handle and unscrew the 2 Torx screws (A 1 +2)

3. push the wooden or décor grill on the door latch lever backward out of the catch and remove the two Torx screws underneath ( B1-2).

4. push the switch of the rear-view mirror (driver’s side) and the grill on the door handle ( C ) ( co-passenger’s side) out of the catch , remove the screw underneath and disconnect the cables.

5. carefully push off the door lining with the plastic clips on the lower and outer door lining edges

6. move the door-lining horizontally and forward away from the inner door metal

8. Crossover circuit - Speaker connection

8.1. precable crossovers - see fig. page 11. 8.2. install crossover – without housing; covered with foamed material- in the hollow space between door build and door-lining above the two woofer in the middle - see fig. ) Check precise fit .

*Important: protect the sheet bar against humidity and observe that the sheet bar does not touch any metal parts – danger of short circuit!

8.3. Insert subwoofer and midrange. connect all loudspeakers to the crossover circuit with the included standard cables for subwoofer to the crossover circuit: parallel wiring see diagram on page 11.

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


All subwoofers must move uniformly!

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










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: Check for precise fit of the panel and remove overlapping parts if necessary.

3 . Panel alignment

Reference points for fitting:

Only precise alignment of the panel with the door lining warrants optimal fit.

ref.point 1A+B: align the cut-out of the door handle in the upper edge of the panel exactly (!) round the front door handle (see fig. 1A+B).

ref.point 2: the back upper edge of the panel has to be aligned exactly (!) intothe moulding of the side edge of the door-lining.

ref.point 3: the lower edge of the panel is parallel to the lower edge of the door lining

✚ ✚

ref.point 3:

fig.1: front edge of the panel

fig.2: enlargement door handle alignment upper edge of the panel

fig.3: enlargement back side edge of the panel and side edge of the door-lining

ref.point 1A:upper edge of the door handle cut-out has to be aligned exactly (!) tothe upper and side edge of the doorhandle

ref.point 1B:align the cut-out ofthe door handle in thepanel exactly (!) belowthe door handle

ref.point 2:align the back upper edge of thepanel exactly (!) to the moulding ofthe side edge of the door-lining

1. use the precisely aligned panel as template in order to mark fastening points 1- 6:

• marking of fixing points 1-6: use a thin awl to set the marks on the door-lining

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

3. take away the door build. Drill the holes for the screws. according to the marks set before. Use a 6mm drill.

4. cut out the speakers’ outlines marked by means of a compass saw (see fig.).: The original speaker cut-out has to be enlarged accordingly.

IMPORTANT: Do not remove the original holding device for the plastic clips!

5. Check again for precise fit and remove overlapping parts of the door-liningall cutting edges of the panel must fit to the door lining snuglyall around without gap

7.5. 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)

7. installation of the door-lining onto the the car doors

7.1. Check up length of the screws and bolts:

in order to prevent damages of mechanic parts of the car doors, please check once again the length of all bolts and screws on the back side of the door lining! No touch with any mechanic parts of the car doors ! (please shorten if necessary).

7.2. reinstall the doorlining horizontally.

7.3. fit it in contrary order of succession as described on page no. 3carefully clip on the plastic pins around the doorling

7.4. carefully screw in the SPAX screws 7-10 through the door panel and the door lining to the door metal. observe cables and mechanic parts !

4. Handling of door lining / Panel installation - Fastening


Do not remove the holdingdevice for the plastic clipson the edges of thedoor-lining.

CAUTION !!

6. screw in the M4 screws supplied with as per 1-6 (see fig.). Screw only hand-tight. Affix the panel to the door-lining. Secure all screws with washers and nuts (hexagonal and sheet metal nuts).

7. check again for precise fit ( see page no.5) and tighten the screws.

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)

important: 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
