Recommendation
The performance of an amplifi er can only be as good as its in-
stallation. A correct installation increases the overall perform-
ance of your car sound system. The GTA amplifi er should be
installed by a trained person. If you 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-performance systems
and loudspeaker confi gurations allows for reaching sound-
pressure levels above 130 dB.
Safety notes
Please observe the following safety notes during the instal-
lation and connection.
– Disconnect the negative pole of the battery! Observe the
safety notes of the vehicle manufacturer.
– When you drill holes, ensure that you do not damage any
vehicle components.
– The cross section of the plus and minus cable may not
be less than 6 mm 2 .
– 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 470 SF must be
secured in a professional way.
When selecting the installation location, select a dry loca-
tion that offers sufficient air circulation for cooling the
amplifi er.
The GTA 470 SF 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 ac-
companying screws and provide a fi rm support.
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.
Use loudspeakers with 2 - 4 Ω impedance (see table or in-
stallation drawing). Observe the maximum power handling
capacity (music output). Do not connect loudspeakers to
earth, use only the referenced terminals.
Amplifi er GTA 470 SF
The amplifi er is suitable for connecting a car sound system
with cinch connections.
For the connection to car sound systems with ISO connec-
tion, use Blaupunkt ISO cinch adapters (7 607 893 093 or
7 607 855 094).

Plus / minus connection
– We recommend a minimum cross section of 6 mm
– Route commercially available plus cables to the battery
and connect via fuse holder.
– Use cable glands for holes with sharp edges.
– Securely fasten commercially available minus cables to a
noise-free earth point (chassis screw, chassis metal) (not
to the minus pole of the battery).
– Scrap the contact surfaces of the earth point until they
are bright and grease with graphite grease.
Integrated fuses (Fuse)
The fuses integrated in the amplifi er (Fuse) protect the power
amplifi er and the entire electrical system in case of an error.
