ABOUT THESE INSTRUCTIONS
Installation of automotive stereo components 
can require extensive experience with a 
variety of mechanical and electrical procedures. 
Although these instructions explain how to install 
Kappa Series multi-element 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.
LOUD MUSIC AND HEARING
Playing loud music in an automobile can hinder 
your ability to hear traffic as well as permanently 
damage your hearing. 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.
REAR DECK PRECAUTION
In some cars, fuel tanks may be located directly 
beneath the rear deck. Before installation, make 
sure there is adequate speaker basket clearance 
before considering this location!
ABOUT THE CROSSOVER
Except for the 462.3cfp, each Kappa Series multielement speaker includes a crossover for in-line 
connection to an amplifier output and is required 
for proper operation (see Figure 7 on the next 
page). The attached crossover wires are keyed and 
color-coded to aid in correct polarity connections.
Do not omit the crossover or substitute another 
one – doing so will damage the speaker.
INSTALLATION TIPS
• Always wear protective eyewear when using 
any tools.
• Turn off all audio components 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.
• 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.

692.3i, 693.3i, 32.3cf or 572.3cf. 
NOTE:The 32.3cf, 462.3cfp and 572.3cf speakers 
are designed to be installed under factory grilles. 
Consequently, no grilles are packaged with 
these models.
NOTE: If you are mounting the 572.3cf in a 6" x 8" 
location, use the adapter provided.

locations requiring fewer than 4 mounting “ears”. 
(The 62.3i and 63.3i may be similarly modified.)
NOTE: Grip the tab with pliers and bend to detach 
it from the speaker.
