3. woofer mounting - original installation location in the vehicle doors.
To protect the woofer and adapter ring from water ingress, we recommend attaching a„Rainstop mat“.
(see Fig. 3.1, gray mat under the mounting ring, included in delivery).
3.1. Cut the Rainstop mat to the size of the mounting ring.
and make a circular cut in the lower area.
Place the mounting ring with the Rainstop mat on the factory
opening with the 6 screws supplied (M4 x 20
(M4 x 20 - hexagonal). At the front and rear, shim with
12 mm washers at the front and rear.
Note: After all woofers are connected to the crossover,
the polarity of all woofers should be checked at a 9 volt battery
(on crossover input cable on radio/power amp side):
Pole of FW input + to + of 9 V battery.
Pole of FW input - to - of 9 V battery
Both woofers must resonate evenly during this check!
A reversed polarity of the woofer can cancel the entire bass response!
To avoid vibration noise, secure all cable harnesses with insulating tape or similar.
ATTENTION!!!
The cable connections of the woofer must not come into contact with the inner door panel --> insulate if necessary.

5. mounting the door panels on the vehicle doors.
Important recommendation:
The use of woofers in the door panel causes vibrations due to the oscillations of the bass,
which can lead to rattling noises in the vehicle door:
Measures against vibration noise:
4.1. insulation of the vehicle doors
- Cover the back of the door trim with insulating fleece (Order No. 27000) or foam material.
or
- Stabilize rear side of door trim with stiffening compound (GRP fiber filler or similar).
IMPORTANT: Make sure to leave the cut-outs for the door airbag and speakers free!
- Cover the *backside of the door panel inside (=outer door skin) with self-adhesive
bitumen mats / tar mats (see example below).
- by tapping the vehicle door, vibration noises of door mechanism parts (e.g. Bowden cables etc.)
and localize cable harnesses and wrap them with foam / felt, foam rubber or similar.
- cut off protruding cable ties (rattling noises!)
- glue felt or foam under the original wiring harness
4.2. insulation of the rear side of the door panel
- Apply insulation fleece (Order No. 27000) to the back of the door trim.
or foam
or
- Stabilize the rear side of the door trim with stiffening compound (GRP fiber filler or similar).
IMPORTANT: Make sure to leave the cut-outs for the door airbag and speakers free!
5.1 Hook the door panel into the top of the door shaft strip.
5.2 Reattach the door trim in reverse order.
Ensure that the clips are unlocked, see Fig.
1. first insulation layer with alubutyl mats
2. second insulation layer with insulation fleece mats
Final check after door panel assembly:
Check all functions of controls such as seat adjustment, glove box opening, window regulator, etc.
