SUBWOOFER POLARITY
Because of the different spatial conditions prevailing in different vehicles, subwoofer po- larity 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 POWER SUPPLY (FIG. 3)
Important, please read carefully.
Connect the +12 v terminal to the +12 v electrical circuit in your car. The +12 v termi- nal of the subwoofer light (fig. 3, right screw terminal) must be connected to the swit- ched positive cable on the vehicle's electrical wiring system via a cable fuse (500 mA
The switched cable is the positive lead in the vehicle connected via the ignition lock (ter- minal 15).
However, terminal 15 is not always able to output sufficient power for the subwoofer light; overload can cause damage to your car's electronics.
The subwoofer light has a power input of 250 mA.
The maximum power value that can be output by the switched cable on terminal 15 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
If the vehicle does not have a switched positive lead or this is not easily accessible, the power supply for the subwoofer light can, as an alternative, be connected to the positi- ve terminal on the car battery via an ON/OFF switch and a 5 amp flink cable fuse.
The negative terminal of the subwoofer light must be connected conductively to the ve- hicle chassis.
