General instructions for installing a HELIX
speaker system
To prevent damage to the speakers and possible in-
jury, read this manual carefully and follow all instal-
lation instructions. This product has been checked
for proper function prior to shipping and is guaran-
teed 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 di-
mension section of this manual. Take care that
the mounting surface is flat and free from all
obstructions.
3.
Ensure that the loudspeakers are correctly con-
nected (phase), i.e. plus to plus and minus to
minus. Exchanging plus and minus may result
in significant loss of sound quality.
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 significant
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 specialist 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 inte-
gral part of an automobile`s safety or structural car
body.
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.
