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

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:

fig. : panel alignment behind the edge of the door lining and the back edge of the panel

45146 - BMW 3 E 36 Sedan / Touring - 5- © JEHNERT SOUND DESIGN

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

�

ref. point 1: 80 mm distancebetween upper edgeof the panel and loweredge of the originaltweeter’s grill

Ref. point 2: 13,5 cm distancebetween end of panel and edge of the door-lining

Ref. point 3: 4,6 cm distancebetween the front

edge of the paneland the side edgeof the door-lining.

Ref. point 2: align “nose” on thepanel directly intothe notch of thedoor lining

Ref. point 4 :


7/16

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

cut-outs of the door lining additional cutout for subwoofer

or alternatively :

5.1. Installation tweeter:

5.2. Installation of loudspeaker cables

5.2.1. carefully remove the moisture protection foil

5.2.2. install cables:

Lead 1 speaker cable (1,5 - 4mm 2) from amplifier into the door. (mount of crossover circuit: back part of the car door/ behind the door – lining) - see page 11

5.2.3. reinstall the moisture protection foil

installation of tweeter in the original mount of the door

• affix the tweeter into the original cut-outs by means of a hot melt adhesive

• connect tweeter cable with the cross-over (length: crossover in the backside of the car door - see fig page 10)

or alternative ….for a wider sound stage image:

installation of tweeter with mounting bowl (see fig.)

• mark the cut-out for the mounting bowl on the door-lining and cut it out exactly by means of a compass saw

• insert the tweeter mounting bowl into the back side of the door-lining and affix it with a hot melt adhesive or silicone

• carefully press the tweeter into the bowl and fix it with hex nut M4x8 and washer. Connect the tweeter with the speaker cable (length: crossover in the backside of the car door - see fig page 10)

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

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)

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


All subwoofers must move uniformly!

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