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 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 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 care-
fully.
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 especi-
ally 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-
ce. 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 cancella-
tion 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 instal-
lation 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 auto-
mobile'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 automotive loudspeakers. This
will allow a trial listening test before securing the loudspe-
akers into their mounting locations.
