General instructions for installing a HELIX
speaker system
To prevent damage to the speakers and possible
injury, read this manual carefully and follow all
installation instructions. This product has been
checked for proper function prior to shipping and
is guaranteed against manufacturing defects.
For a proper performance and to ensure full war-
ranty coverage, we strongly recommend to get this
product installed 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 fit into
the intended mounting location and that there
is adequate depth for the magnet system.
2. Check for adequate space between speak-
er and window, window crank, power win-
dow 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
dimension section of this manual. Take care
that the mounting surface is flat and free from
all obstructions.
3. Ensure that the loudspeakers are correctly
connected (phase), i.e. plus to plus and minus
to minus. Exchanging plus and minus may
result in significant loss of sound quality.
your purchase of
speaker system generation sets new standards.

We wish you many hours of enjoyment with your
new HELIX speakers.

4. Make sure that the crossovers are mounted
properly.
5. Do not mount the speakers and crossovers
where water may splash on them.
6. The quality of the installation has a signifi-
cant effect on the overall performance of the
speaker system. Treat each installation step
with a high degree of attention.
7. Avoid low frequency cancellation caused by
air leakage between the speaker basket and
the mounting surface (e.g. mounted on a
bended or uneven surface or mounted in an
oversized hole).
8. Mounting panel reinforcement may be neces-
sary in some cases in order to ensure a sta-
ble, torsion-free and even surface. This can
be achieved by mounting the speaker on a
metal or wooden sub-baffle behind the body
or door panel. Consult an installation special-
ist for further advices.
9. In most cases you can use the original speak-
er mounting locations in the doors, body pan-
els or the rear deck. If these are not available
you have to prepare your own secure installa-
tion 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 in-
tegral part of an automobile`s safety or structural
car body.
