components can require extensive experience
with a variety of mechanical and electrical procedures. Although these instructions explain how to
install a Kappa Series 3-Way Component System
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 automotive
environment 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.
SPEAKER PLACEMENT
Kappa speakers are designed to be easily
installed in stock speaker locations. While mounting your speakers in the original factory locations
will, in most cases, provide excellent sonic
results, the best sounding installations are a
result of adherence to a few basic rules:
• For the most spacious stereo image, place the
left and right speakers as far apart as possible.
• For enhanced center image, place the left and
right speakers so they are equidistant from the
listening position. If possible, try to place them
as far forward as possible.
• For best treble response aim the tweeters
toward the listening position, and be sure there
are no obstructions between the tweeters and
the listener.
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 components 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

declare in own responsibility, that the products described in this owner’s manual are in compliance with technical standards:
EN 50 081-1/1992
EN 50 082-1/3.1995
ADJUSTING THE SOUND
After you have connected all the speakers to the
crossover according to the connection diagram,
you may adjust the overall sound of the system to
suit your taste.
The output of the woofers may be decreased by
moving the woofer + connection at the crossover
to the low position.
The output of the midrange may be decreased by
moving the midrange + connection at the
crossover to the low position.
The output of the tweeter may be increased by
moving the tweeter + connection at the crossover
to the high position or decreased by moving it to
the low position.
A NOTE ON POWER HANDLING
The speakers used in Kappa Series 3-Way
Component Systems are designed to produce reasonable volume levels with little amplifier power.
However, the addition of an amplifier to drive
your speakers and a subwoofer will enhance the
dynamic range of your system, and help overcome the ambient noise in a moving vehicle.
Kappa speakers are designed to handle the power
of a dedicated amplifier driven at or below its
rated power. If an amplifier is driven far above its
rated power, the output signal will “clip,” and the
additional power present in a clipped signal can
damage any speaker. Distorted or “fuzzy” sound
from your speakers is an indication that the amplifier has exceeded its rated power, and you should
reduce the volume level
GENERAL CARE
The loudspeaker grilles may be cleaned with a
slightly damp cloth. Do not use any cleaners or
solvents on the grilles or the speaker cones.
