General information
This manual has been designed to make HELIX ESPRIT
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 insu rance 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 ESPRIT
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 installa-
tion read the following information and precautions careful-
ly.
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 inten-
ded mounting location and that there is adequate cavity
depth to accept the magnet structure.
B.Check for adequate clearance between speaker and win-
dow, 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 surface.
Check for a flat mounting surface, free 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 spe-
aker (such as when mounted on a curved or uneven surfa-
ce, 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 spe-
cialist 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 pre-
cut 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 ESPRIT Speaker Installation
NOTE. HELIX strongly recommends that you operate the
complete audio system at low volume before final installa-
tion of your HELIX ESPRIT automoti ve loudspeakers. This
will allow a trial listening test before securing the loudspea-
kers into their mounting locations.
