Crossover Network
: The crossover terminals area are separated as red zone and
black zone: all connectors on red zone are positive (+) and all connectors on black
zone are negative (-). Wires from the amplifier outputs must be connected on
terminal labeled IN+ and IN-. The positive and negative outputs of the woofer
connections are labeled W+ and W- on the crossover and should be connected
to corresponding terminals on woofer. The tweeter connections are labeled as TW+
and TW-. Wires out of tweeter use black and red insulator tubes, red (positive)
must be connected to TW+. The crossover can be fixed directly to the woofer
frame by a slide joint and locked by a screw, or it can be used separately and fixed
in another place inside the car.
Changing from Coaxial to Separate Components
: The 3.69C factory configuration
is coaxial. To change configuration to separate components follow these steps:
1- Unplug the tweeter wires from crossover network (Fig 1).
2- Unscrew the long back screw with T20 Torx screwdriver and remove it completely
(Fig. 2). These screws will be not used on separate system, but can be saved for
go back to previous setting.
3- Remove the back cup cover (Fig. 3).
4- Pull up the tweeter wires in vertical position and remove the entire tweeter and
tweeter holder from the center of woofer (Fig. 4).
5- Now instead of the tweeter holder insert the ABS plug (Fig. 5).
6- Put the rear cup back (note the two pins must be located on two slots on side
wall) and secure everything with the (short) M4x8 mm screw (Fig 6).
7- Tweeter: with a small slotted screwdriver remove the three rubber rings (o-rings)
starting from the closest to the tweeter to the farthest. The screwdriver must be
inserted on dedicated slot located opposite the tweeter cables (Fig 7).
8- Lift the cables from the slots where they are inserted and gently remove the
tweeter by pulling and turning slightly. Route the cables through the slot on the
holder (Fig 8).
At this point the tweeter can be used separately with one of the supplied
accessories. Refer to 3.25 installation manual. 3.165C is shown in the drawings, the
procedure is the same for 3.69C.
