Warranty
We provide manufacturer's warranty for 12 months
from the date of sale for products purchased within
India.
Recommendation
The performance of an ampli er can only be as good as
its installation. Correct installation increases the overall
performance of your car sound system. The GTA
ampli er should be installed by a trained person. If you
would like to install it yourself, please read these
installation instructions very carefully and allow yourself
sufficient 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 con 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 terminal of the battery!
Observe the safety notes of the vehicle manufacturer.
- When you drill holes, ensure that you do not damage
any vehicle components.
- Please use minimum 10AWG power & ground cable
with a fuse located within 18 inches of the battery.
- Use cable glands for holes with sharp edges.
- An incorrect installation can result in malfunctions of
the electronic vehicle systems or sound system.
Installation and connection instructions
With respect to accident safety, the GTA 260 must be
secured in a professional way.
When selecting the installation location, select a dry
location that offers sufficient air circulation for cooling
the ampli er.
The GTA 260 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 rm support.
The ampli er power cable must be 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
ampli er and battery. The fuse of the ampli er protects
only the ampli er, not the vehicle battery.
Use loudspeakers with 2 - 4 Ohms impedance (see table
or installation drawing). Do not connect loudspeakers to
ground, use only the referenced terminals.

Audio inputs (see Fig. 3)
You can select between 2 different audio inputs;
- Cinch (RCA)
- Hi level (loudspeaker connections)
Use only one of the audio inputs; otherwise, it may lead
to audio interference.
The preampli er outputs are connected to the cinch
(RCA) sockets
j
) via a shielded sound cable.
With control via the loudspeaker outputs, the input
connections of pos.
k / l are fed to the closest
loudspeaker cables (front or rear) on the left and right.
They are separated and connected to the input
connections. The polarity of the +or - connections must
be observed. Bridge output stages (BTL) can also be
connected directly without an additional adapter.
Positive / negative connection
- We recommend a minimum cross section of 10 AWG
- Route commercially available positive cable to the
battery and connect via fuse holder.
- Use cable glands for holes with sharp edges.
- Securely fasten commercially available negative
cables to a noise-free ground point (chassis screw,
chassis metal) not to the negative pole of the battery.
