General instructions for installing HELIX
loudspeakers
To prevent damage to the speakers and possible inju-
ry, read this manual carefully and follow all installation
instructions. This product has been checked for proper
function prior to shipping and is guaranteed against man-
ufacturing defects.
For a proper performance and to ensure full warranty
coverage, we strongly recommend to get this product in-
stalled by an authorized HELIX dealer.
If you choose to perform your own installation read the
following information and precautions carefully.
Failure to follow the stated precautions may result in
personal injury and / or damage to the audio system or
vehicle.
1. Always make sure that the speaker will t into the in-
tended mounting location and that there is adequate
depth for the magnet system.
2. Check for adequate space between speaker and
window, window crank, power window mechanism,
seat, rear deck torsion bars, and other items which
may interfere with the speaker`s mounting. This
is very important if any hole cutting is required.
Detailed size information is indicated in the dimen-
sion section of this manual. Take care that the mount-
ing surface is at and free from all obstructions.
3. Ensure that the loudspeakers are correctly connect-
ed in polarity. Exchanging plus and minus may result
in signicant loss of sound quality. The positive leads
of the loudspeakers are marked red.
4. 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,
amplier and / or speaker system.
5. Verify that all connection wires are long enough in
order to avoid any mechanical stress on the wires or
the connectors.
6. Make sure that all components are mounted properly.
7. Do not mount the components where water may
splash on them.
8. The quality of the installation has a signicant eect
on the overall performance of the speaker system.
Treat each installation step with a high degree of
attention.
9. Avoid low frequency cancellation caused by air leak-
age between the speaker basket and the mounting
surface (e.g. mounted on a bended or uneven sur-
face or mounted in an oversized hole).
10. Mounting panel reinforcement may be necessary in
some cases in order to ensure a stable, torsion-free
and even surface. This can be achieved by mounting
the speaker on a metal, plastic or wooden sub-bae
behind the body or door panel. Consult an installa-
tion specialist for further advices.
11. In most cases you can use the original speaker
mounting locations in the doors, A-pillars, body pan-
els or the rear deck. If these are not available you
have to prepare your own secure installation place.
Due to their structural integrity and accessibility the
precut mounting holes should be used whenever
possible. Information on a proper mounting can be
found in the section “Installation” of this manual.
IMPORTANT: Never cut any metal that is an integral part
of an automobile`s safety or structural car body.
We strongly recommend that you operate the complete
audio system at low volume before nal installation. So
you can check whether each speaker is working before
securing the loudspeakers into their mounting locations.
Congratulations!
