IMPORTANT: Installation of automotive stereo
components can require extensive experience
with a variety of mechanical and electrical
procedures. Although these instructions explain
how to install Reference Series speakers in a
general sense, they do not show the exact
installation methods for your particular vehicle.
If you do not feel you have the experience, do not
attempt the installation yourself, but instead ask
your authorized Infinity car-audio dealer about
professional installation options.
WARNING: Playing loud music in an automobile
can permanently damage your hearing, as well as
hinder your ability to hear traffic. The maximum
volume levels achievable with Infinity speakers,
combined with high power amplification, may
exceed safe levels for extended listening. We
recommend using low volume levels when
driving. Infinity accepts no liability for hearing
loss, bodily injury, or property damage as a result
of use or misuse of this product.
INSTALLATION WARNINGS AND TIPS
• Always wear protective eyewear when using
any tools.
• Turn off all audio systems and other electrical
devices before you start. Disconnect the (
–)
negative lead from your vehicle’s battery.
• Keep speakers in their package until final
installation. When moving a speaker, always
rest it with the cone or dome facing up. Never
use force to install any speaker.
• Check clearances on both sides of a planned
mounting surface before drilling any holes or
installing any screws. Remember that the
screws can extend behind the surface.
• At the installation sites, locate and make a note
of all fuel lines, hydraulic brake lines, vacuum
lines, and electrical wiring. Use extreme caution
when cutting or drilling in and around these
areas.
CAUTION: In some cars, fuel tanks may be
located directly beneath the rear deck. Check
for adequate speaker basket clearance before
considering this location!
• Before drilling or cutting holes, use a utility
knife to remove unwanted fabric or vinyl, to
keep material from snagging in a drill bit or
saw.
• For door installations, check the clearance with
the windows throughout the range of the
window’s travel, and verify that a mounted
speaker will not interfere with the window
crank or power window mechanism.
• If mounting speakers elsewhere, check for
clearance around rear deck torsion bars, glove
box, or other structural elements.
• Do not mount speakers where they will get wet.
