Mechanical Installation Tip
Warning: First disconnect negative pole of your car battery. Check-
polarity, changing polarity may cause serious damage to your car electric.
Best speaker positions are the original build in positions. Easy installation
and original look are the reasons.
Please note that the speakers are installed flat and stable. The quality of
the installation decides very much the sound, therefore, attention should be
paid to insulation and care during installation. Please note that the speakers
are protected from heat, sunlight, mechanical influences, moisture and wetness
by accessories from AUDIO SYSTEM.
Attention: Install all cables as straight as possible without squashing or
laying them over sharp edges. Otherwise this can cause short circuit or
damages to your whole installation.
Attention: Be careful removing original plastic parts of your car. The
fitting parts could be damaged and have to be replaced.
Important: The right polarity of all speakers is extremely important for
the sound of your car audio system.
We recommend changing polarity of the tweeter finding
out the best possible sound.
The best is to listen and/or to measure it.
