SUBWOOFER POLARITY
Because of the different spatial conditions prevailing in different vehicles, subwoofer
polarity can best be determined by trial and error. To do this, choose some music material
you know very well and select the setting you like most. Some radios / control units also
offer the possibility of setting the polarity on the appliance itself (phase). One change in
polarity corresponds to a phase shift of 180 degrees.
CONNECTING THE ILLUMINATION (FIGURE 3)
Important, please read carefully.
Connect the +12 v terminal to the +12 v electrical circuit in your car. The +12 v terminal
of the subwoofer light (fig. 3, right screw terminal) must be connected to the positive cable
on the vehicle's electrical wiring system via a cable fuse (500 mA slow-blow, precise
specification: T500mAL 250 volt, fuse and fuse holder not supplied).
Now connect the car hi-fi receiver's remote control connection to the amplifier's REM
control jack on the terminal (Fig. 3, middle terminal screw). A cable with a cross-section
of 0.75 mm² is sufficient for connecting the amplifier's REMOTE connection to the control
device.
The maximum power value that can be output by the remote control line must be
observed. If this is not sufficient, an electronic relay connection must be added.It is
therefore advisable to have the installation carried out by a qualified auto-electrician,
especially if you are not familiar with the electrical wiring system on your vehicle.
The negative terminal of the subwoofer light (Fig. 3, left terminal screw) must be
connected conductively to the vehicle chassis.
Fuse, fuse holder (cable fuse), relay connection and switch are available from specialist
dealers.
N.B.!
On no account may the light remain permanently connected to the battery, as the battery
will otherwise discharge within a few days. When using a separate switch connected to
the battery, the light must be switched off when leaving the vehicle.
