Recommendation:
The performance of an amplifi er can only be as good
as its installation. A correct installation increases the
overall performance of your car sound system. The THA
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 installation 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 1.5 mm
- 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 THA 475 PnP 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 installation surface must be suitable to accept the
accompanying screws and provide a fi rm support.
2
(A.W.G. 16).
The amplifi er power cable must be fi tted with a
fuse no more than 30 cm from the battery (see Fig. 2a)
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
loudspeakers to earth, use only the referenced
terminals.
