Instructions for installation and
connection
Fit a fuse in the amplifier power line no more
than 30 cm from the vehicle battery, in order
to protect the battery in the event of a short-
circuit between it and the power amplifier. The
amplifier’s own fuse protects the amplifier its-
elf, but not the car battery.
Disconnect the negative terminal of the
battery before carrying out installation
and connection work.
Observe the vehicle manufacturer’s safety in-
structions (regarding airbags, alarm systems,
trip computers, vehicle immobilisers).
The final stage must be installed professional
-
ly for reasons of safety. The mounting surface
must be suitable for the screws provided, and
must provide firm support. For safety reasons
the GTA 1350 should be fixed in a reliable way.
You must not install the GTA 1350 on the rear
shelf, on the rear seats or on any other surface
open to the front.
When drilling holes, take care to avoid damage
to vehicle components (battery, cables, fuse bo
-
xes).
Fit the amplifier in a suitable location, e.g.
beneath the seats or in the trunk (Fig. 1).
The mounting location must also be dry, and
provide sufficient ventilation for cooling of
the amplifier. Use cable grommets when pas
-
sing cables through holes with sharp edges.
Use loudspeakers with an impedance of
2 to 4 (see table or installation drawing). Ob
-
serve the max. power handling specifications
(music output). Do not connect the loudspea-
kers to ground; only use the terminals provided.
The cross-section of the positive and negative
cable must be at least 10 mm
2
.
GTA 1350 amplifier
The amplifier is suitable for connection to car
radios with Cinch connector. Use the Blaupunkt
ISO Cinch adapter to connect the amplifier to
car radios with ISO connector (7 607 893 093/
7 607 855 094).

Positive/negative connection
We recommend a cable cross-section of not
less than 6 mm
2
. Run a standard commercial
positive cable to the battery and connect to the
fuse holder. Use cable grommets when passing
cables through holes with sharp edges. Bolt a
standard commercial negative cable to a ground
point free of induced noise (car body bolt, body
panel) - not to the negative battery pole. Clean
the contact surface of the ground point down
to bare metal and coat with antiseize graphite
petroleum.
Integral fuses
The integral fuses within the amplifier protect
the final stage and the entire electrical system
in the event of a fault. Never bridge fuses or re
-
place fuses with a higher current rating.
