General information
This manual has been designed to make HELIX PRECISION automotive loudspeaker installation and ownership
as trouble-free as possible. Please read through this
manual completely before attempting any installation
steps and familiarize yourself with your new speaker
system.
You will need your purchase receipt as proof of purchase for any and all warranty repairs and for insurance purposes. Keep your receipt, owner's manual, and packing
materials in a safe location for possible future use.
Pre-installation instructions
It is recommended that you have your new HELIX PRECISION automotive loudspeakers professionally installed
by your authorized HELIX dealer. This will ensure the use
of proper installation techniques and materials, and will
save much time and effort. 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 the audio
system or vehicle.
A. Always make sure the speaker will easily fit into the
intended mounting location and that there is adequate
cavity depth to accept the magnet structure.
B. Check for adequate clearance between speaker and
window, window crank, power window mechanism, seat,
glove box, rear deck torsion bars, and other items which
may interfere with the speaker's mounting. This is especially important if any hole cutting is required.
Complete speaker, mounting size and depth requirements can be found at the end of this manual. A good
way to confirm speaker place meet on a door or body
panel is to place the speaker's die cast mounting ring
onto the surfa
from all obstruction.
C. The method of installation chosen and level of execution will effect the overall performance of the speaker
system. Treat each installation step with a high degree
of attention.
D. Do not mount the speaker where water may splash
the woofer cone.
A plastic cup or some heavy gauge plastic sheeting may
be needed in some locations that are exposed to moisture from behind the body panel.
E. Care must be taken to prevent low frequency cancellation caused by air leakage between the front and rear
of the speaker (such as when mounted on a curved or
uneven surface, or when mounted in an oversized hole).
F. Mounting panel reinforcement may be necessary in
some cases in order to prevent surface flex. 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 direction.
G. Unless you are replacing existing speakers of same
size, mounting locations will have to be cut into the
doors, body panels, or rear deck. In some cases speaker
mounting holes will be precut in the doors, body panels,
or rear deck steel. Due to their structural integrity and
accessibility. These precut mounting holes should be
used whenever possible.
IMPORTANT:
Never cut any metal that is an integral part of an
automobile's safety or structural supportsystem.
HELIX PRECISION Speaker Installation
NOTE. HELIX strongly recommends that you operate the
complete audio system at low volume before final installation of your HELIX PRECISION automotive loudspeakers. This will allow a trial listening test before securing
the loudspeakers into their mounting locations.
ce. Check for a flat mounting surface, free

CAUTION:
Make sure that all speaker wiring is fully protected from cutting or wear. Any short circuits developing as a result could severely damage the
radio/cassette unit or amplifier. Make sure that
all speaker wires easily reach the speaker terminals with stress on the wire or connectors.
Securing the loudspeaker
Once you have tested the complete speaker system and
have confirmed correct operation, turn the audio system
off and prepare the loudspeaker for final mounting.
