If the indicator LED POWER (5) lights up,
set the volume of the car radio to about
75% of the maximum volume.
Now, use the X-OVER control unit(s) (3)
to adjust the maximum volume of the
loudspeakers to a value which is
acceptable for you. If you use several
amplifiers, match the volumes of the dif-
ferent amplifiers one to the other.
Then, set an average volume level via
the volume control unit of the car radio.
To reach an optimum sound, you can
slightly adjust the set cut-off frequencies
via the HPF (1) and LPF (2) control units.
If the low-bass playback is too weak,
you can activate a two-stage low-bass
amplifier via the SUPER BASS switch (6)
.

all connections and loudspeakers. If
you cannot detect an error, please con-
tact a specialist for help.
Take care that the maximum volume
depends on the power capacities of the
loudspeaker and amplifier. Excessive
volume can damage the loudspeakers
and amplifier.
A timing signal can be heard in case of
overload.
From now, the total volume is only set
by the volume control unit of the car
radio.
Make sure that the frequency ranges
indicated by the loudspeaker manufac-
turer are not exceeded during setting
operations.
If you use a subwoofer, the change of
polarity of the loudspeaker connecting
cables may improve the sound quality.
Often, the reverse terminal position
causes
(depending on the place of installation
of the subwoofer).
