Installation and connection instructions
With respect to accident safety, the GTs 6902 A
must be secured in a professional way.
The GTs 6902 A may be installed only in the
spare wheel well and not on rear shelves,
rear seat benches or other locations that are
open to the front.
Use suitable threaded rods or ratchet straps
to ensure a fi rm support (see Fig. 1).
The amplifi er power cable must be fi tted with a fuse no more
than 30 cm from the battery to protect the vehicle battery in
case of a short circuit between power amplifi er and battery.
The fuse of the amplifi er protects only the amplifi er, not the
vehicle battery.
Switching on/off
One of the special features of the GTs 6902 A is its automatic
switch-on.
The subwoofer box automatically switches on if a music
signal is received.
If there is no music signal for more than 60 seconds, the
GTs 6902 A automatically switches off .

The control of the GTs 6902 A should ideally be a two-
channel control, either via the preamplifi er outputs or the
loudspeaker outputs of the car sound system. A control
solely via the right or left channel is also possible since the
low-frequency portion of the music is generally identical
on both channels.
Audio inputs
You can select between 3 diff erent audio inputs;
–
Cinch (RCA)
–
Hi level (loudspeaker connections)
–
RF Link (wireless transmission)
Use only one of the audio inputs; otherwise, it may lead to
audio interferences.
