IMPORTANT
Installation of automotive stereo compo-
nents can require extensive experience per-
forming a variety of mechanical and electri-
cal procedures. Although these instructions
explain how to install a Kappa Perfect6.1
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.
WARNING
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.
SPEAKER PLACEMENT
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.
A NOTE ABOUT SYSTEM PERFORMANCE
For the best performance possible, the
Kappa Perfect6.1 should be used with a
two-channel amplifier with output power of
at least 35W 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 4th-order Linquitz-Riley acoustic
alignment and cannot be duplicated with
any electronic crossover currently available
for car-audio use. Consequently, bi-amping
the Perfect6.1 with an electronic crossover
is not recommended.
