Mechanical Installation Tip
Warning: First disconnect the 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 originality are the reasons.
Please note that the speakers are flat and stable. The quality of the
installation decides the sound very much, 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 the AUDIO SYSTEM.
Attention: Lay all cables as straight as possible without squashing or laying
them over sharp edges. Otherwise, this can cause a short circuit or damage to
your whole installation.
Attention: Be careful removing original plastic parts of your car.
The fitting parts could be damaged and must be replaced.
Important: The right polarity of all speakers is extremely important for the
sound of your car audio system. We recommend changing the polarity of the
subwoofer to find out the best possible sound. The best is to listen or
measure it!
