Installation and positioning

Woofer and woofer-midrange

recommendations
K2 Power woofers and woofer-
midranges have been designed for
a multitude of vehicles installations.
It is worth understanding the basic
requirements for installing
products. These woofers and woofer-
midranges are capable of delivering
enormous amounts of energy, during
their positive/negative
Therefore it is imperative that they
be fixed rigid to the desired location.
The fixing location should
be strengthened where necessary.
Panels should be strengthened to
eliminate any unwanted vibrations.
Such vibrations will drastically reduce
the overall performance. These drive
units should be fixed and sealed to
the baffle or location panel. The use
of the foam gasket is advisable for
correct air sealing.
For added performance, and to better
reduce such unwanted vibrations
and other acoustical losses, we
recommend the use of "plain chant".
Easily positioned behind the woofer,
on the metal-work of the vehicle, Plain
Chant soaks-up vibrations as well as
acoustic reflections.
Always ensure before that enough
space is available for the magnet
assembly, that it doesn't interfere with
safety mechanisms or general working
parts.
In the case of not using the grilles

speakers will fit correctly. Ensuring
there is enough depth behind the

given for the forward movement of the

If necessary, place the supplied screw
fixing clamps. Fix the round gasket
on the back of the woofer chassis.
Remove the metallic grille from the
rest of the grille. Make the grille holes
coincide with the ones of the driver,
fix with the supplied screws. Stack the
metallic grille (pic. H).

Crossover

To access some crossover settings, you
must remove the translucent cap with
the 4 screws (pic. I).
2-way kit wiring (165 KRX2 and
165 KRXS)
Plug the amplifier output on the "IN"
inputs of the crossover.
Connect the woofer on the "W" output
and the tweeter on the "T" (pic. J).
3-way kit wiring (165 KRX3)
Plug the amplifier output on the "IN"
inputs of the crossover.
Connect the woofer on the "Woofer"
output, the midrange on the "Mid"
output and the tweeter on the
"Tweeter" output (pic. K).
Finally always ensure the tweeter
and woofer are connected in phase
correctly, thus polarities are respected
"+" to "+", and "-" to "-". If not done
correctly a "hole" or "peak", may
result, due to a shift in phase. This
will dramatically impair the overall
performance.
