General installation instructions for HELIX
components
To prevent damage to the unit 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.
Before starting your installation, disconnect the
battery's negative terminal to prevent damage
to the unit, fire and / or risk of injury. For a proper
performance and to ensure full warranty coverage,
we strongly recommend to get this product installed
by an authorized HELIX dealer.
1. Check that the space between the active sub-
woofer and other parts, such as the car seat
etc., is sufficient.
2. Take care that the mounting surface is flat and
free from all obstructions.
3. Ensure that the active subwoofer is correctly
connected (phase), i.e. plus to plus and minus
to minus.

When screwing the active subwoofer to the ve-
hicle chassis, carefully examine the area
around and behind the proposed installation lo-
cation to ensure that there are no electrical ca-
bles or components, hydraulic brake lines or
any part of the fuel tank located behind the
mounting surface. Failure to do so may result in
unpredictable damage to these components
and possible costly repairs to the vehicle.
5. Do not mount the active subwoofer where water
may splash on it or close to heat-radiating parts
and electronic controls of the vehicle.
6. The quality of the installation has a significant
effect on the overall performance of the active
subwoofer. Treat each installation step with a
high degree of attention.
