General instructions
3. Then connect the wires of the tweeter to the
crossover (
– TW +
). It is possible to change
the loudness level of the tweeter by reposition-
ing a jumper on the inside of the crossover:
+2 dB: If the jumper will be set to this plug po-
sition the level of the tweeter is increased by
+2 dB.
0 dB: If the jumper is set to this plug position
the tweeter has the optimum level for most
applications.
-2 dB: If you choose this plug position, the
level of the tweeter is reduced by 2 dB.
0 dB -2 dB +2 dB
Attention: Ensure that all components are correctly
connected (phase), i.e. plus to plus and minus to
minus. Exchanging plus and minus will result in a
significant loss of sound quality.
The positive leads of the loudspeaker system are
marked with a red stripe.
General instructions for connecting HELIX
speaker systems
We strongly recommend that you operate the com-
plete audio system at low volume before final instal -
lation. So you can check whether each speaker is
working before securing the loudspeakers into their
mounting locations.
Make sure that all speaker wiring is fully protected
from cutting or wear at sharp edges, which can lead
to short circuits that may damage your head unit,
amplifier and/or speaker system.
Make sure that all speaker wires are long enough in
order to avoid any mechanical stress on the wires
or the connectors.
Attention: Ensure that the loudspeakers are cor-
rectly connected (phase), i.e. plus to plus and minus
to minus. Exchanging plus and minus will result in a
significant loss of sound quality.
General instructions for mounting HELIX speak-
er systems
Once you have tested the complete speaker system
and have confirmed correct operation, turn off the
audio system and prepare all loudspeakers for final
mounting.
1. Place the loudspeaker in the mounting posi-
tion as shown in the illustration “Mounting the
woofer”.
2. Fix the speaker with its mounting ring in its
installation place and check if all screws are
properly aligned with the fixing holes. Use the
included screw clips to secure the screws.
Tighten all screws evenly.
3. Attach the grille to the mounting ring.
