8.2. install crossover under the dashboard. Check precise fit.
8.3. Insert subwoofer and midrange and connect all loudspeakers
(car door: midrange and subwoofer / dashboard: tweeter)
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!
Wrong polarity of a subwoofer can totally
equalize the bass sound!

6. insulation of the door lining
Important tip:
the use of woofers 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

5.3. install cables:
Lead 1 speaker cable (1,5 - 4mm 2) from amplifier into the door.
(mount of crossover circuit: under the dashboard.
5.4. reinstall the moisture protection foil

7. installation of the door-lining onto 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)
1.1. place the door-lining backside up on a plane surface
1.2. align the adapter plate with speakers instead of the factory installed speaker unit
1.3. mark the outlines of the adapter plate and remove the plate again
fitting of adapter plate 75075 –model up to ‘96:
1. sand the outline marked (adhesive property will be better then)
2. put hot melt adhesive on the outlines.
3. fit in the adapter plate exactly and hold it fast to the door-lining until
the adhesive hardens
fitting of adapter plate 76075 –model from ‘96:
1. sand the outline marked (adhesive property will be better)
2. original screwed joint within the outline marking is used to install the
adapter plate:
•detach original screwed joint
•install adapter plate exactly and tighten the screws
3. put holt melt adhesive on the rest of the plate edge.
4. connect subwoofer and midrange with speaker cable (1,5-4mm2) and lead cable
to the mount of the crossover circuit.
Length of cable: up to crossover- mount underneath the dashboard
Remark:
rubber surround of subwoofer touches the expanding rivets of the speaker grills.
But this does not affect the sound (no vibration noise).

8.1. precable crossovers - see fig. page 11.
8.2. install crossover under the dashboard. Check precise fit.
8.3. Insert subwoofer and midrange and connect all loudspeakers
(car door: midrange and subwoofer / dashboard: tweeter)
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!
Wrong polarity of a subwoofer can totally
equalize the bass sound!

3.6. Install the tweeter with the perforated sheet metal in the original mount
and lead the speaker cable to the mount of the crossover.
.
Acoustic TIP:
adjust the tweeter in an angular position to the inner rear
view mirror (not driver’s or co-passenger’s side)

3. tweeter installation in standard mount of the dashboard
You should check the polarity of all woofers after having
connected them to the crossover circuit with a 9 volt battery
(input cable on the side of the amplier).
Recommendation:
Install both crossovers on the passenger‘s side underneath the airbag.
*Important:
Protect the sheet bar against humidity and observe that the sheet
bar does not touch any metal parts – danger of short circuit!

our recommendation:
adjust the balance two points further to
the right side (from driver’s side) –may vary
according to the different types of radios.
