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.
