Infiniti 5.1 User Manual

Installation of automotive stereo components
can require extensive experience performing
a variety of mechanical and electrical proce-
dures. Although these instructions explain
how to install a Kappa Perfect component
system in a general sense, they do not 
show the exact installation method for your 
particular car. If you feel you may not have
the necessary tools or experience, ask your
authorized Infinity car audio dealer about 
professional installation options.

Playing loud music in your automobile can
permanently damage your hearing as well 
as hinder your ability to hear traffic. We 
recommend listening at low volume while
driving. Infinity accepts no liability for hear-
ing loss, bodily injury or property damage
resulting from use or misuse of this product.

For the best performance possible, the 
Kappa Perfect components should be used
with a two-channel amplifier with output
power of at least 50W RMS per channel. 
The passive crossover contains impedance-
compensating circuitry and has been 
computer-optimized for the flattest possible
frequency response with the tweeter flush-
mounted, on-axis with the listener. The 
combined responses of the speakers and
passive crossover constitute a 4th-order
Linquitz-Riley acoustic alignment and cannot
be duplicated with any electronic crossover
currently available for car audio use.
Consequently, bi-amping a Perfect 
component system with an electronic
crossover is not recommended. 

Figures 1– 4 show possible speaker place-
ments in the order of most desirable to
least desirable. Kick-panel mounting will
provide the best staging and imaging in
most vehicles.
