would to install it yourself, please read these installation
instructions very carefully and allow yourself suffi cient
time for the installation.
In conclusion, allow us a few words about the topic of
health protection:
During the playback of music in your vehicle, please
consider that continuous sound-pressure levels above
100 dB can lead to permanent damages to the human ear
and even to loss of hearing. Using today's high-perform-
ance systems and loudspeaker confi gurations allows for
reaching sound-pressure levels above 130 dB.
Safety notes
Please observe the following safety notes
during the installation and connection.
-
Disconnect the negative pole of the battery!
Observe the safety notes of the vehicle manufac-
turer.
- When you drill holes, ensure that you do not dam-
age any vehicle components.
- The cross section of the plus and minus cable may
not be less than 6 mm
2
(5 A.W.G.).
- Use cable glands for holes with sharp edges.
- An incorrect installation can result in malfunctions
of the electronic vehicle systems or your car sound
system.
Installation and connection instructions
With respect to accident safety, the GTA 280 must be
secured in a professional way.
When selecting the installation location, select a dry
location that offers suffi cient air circulation for cooling
the amplifi er.
The GTA 280 must not be installed on rear shelves, rear
seats or other locations that are open to the front.
The installation location must be suitable to accept the
accompanying screws and provide a fi rm support.
The amplifi er power cable must be fi tted with a fuse no
more than 30 cm (1,18") 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.
Use loudspeakers with
2-4 Ω
impedance (see table or
installation drawing). Observe the maximum power
handling capacity (music output). Do not connect loud-
speakers to earth, use only the referenced terminals.
Amplifi er GTA 280
The amplifi er is suitable for connecting a car sound
system with cinch connections.
For the connection to car sound systems with
ISO connection, use Blaupunkt ISO cinch adapters
(7 607 893 093 or 7 607 855 094).
