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 movement.
Therefore it is imperative that they
be fixed rigid to the desired location.
The fixing location should also
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
supplied, it is important to ensure
the speakers will fit correctly. Ensuring
there is enough depth behind the
speaker has already been explained,
but enough thought must also be
given for the forward movement of the
cone and surround assembly.

Woofer and woofer-midrange
installation, simple steps (with grille)
Either cut the required hole or use the
correct hole of choice. Note correct
diameter (fig. F). Where necessary,
carefully push in the four fixing clips to
such accept the fixing screws later.
Carefully place the
ensuring it lines-up with the holes or
fixing clip positions.
Fix the foam gasket to the back of the
drive unit chassis. Add a small amount
of glue where necessary, so it remains
in the correct position (line-up holes).
Lower the drive unit above the fixing
ring, so it remains in the correct
position (line-up holes).
Don't forget to connect up the cable
to the connectors.
Now lower the drive unit and screw in
place, with the 4 screws provided.
Now add the grille and push in place.
Ensure the logo is straight.
Crossover installation, simple steps
First before any work is started it is
necessary to remove the clear plastic
lid (fig. G).
Doing so enables
adjustment, and fixing the unit in
place.
Remove, by pushing gently on the two
shortest sides of the clear plastic lid.
Then pull off.
Never use a screwdriver to prise
off the lid, otherwise damage will
probably occur, not covered by the
warranty.
Once removed, fix in place with the
4 screws supplied. Ensure the length
of screw is suitable for the desired
location. Always ensure the crossover
is installed in a dry and vented area,
without risk of humidity.
2-Way kits connecting up, simple steps
Connect the output from the amplifier
into the input of the crossover "IN".
Connect the woofer to the output of
the crossover "W".
Connect the tweeter to the output of
the crossover "T" (fig. H).
fixing ring, 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.
3-Way kits connecting up (165 K3P)
The 165 K3P uses two crossovers,
connected together. The exclusive
165 KBP low frequency cross-over,
has two configurations for filtering.
These being mode:
"High Pass" (fig. I, and K), for a true
3 way set-up, with separate bass mid
and high frequencies.
"Full" (fig. J, and L), for a 2+1 way
set-up, with 2x165mm in parallel, for
more dynamic fast bass.
access for
Important (165K3P)
Depending on the preferred set-up,
the selector found in the 165KBP , must
be switched accordingly.
The mode "Full" (F),requires inverting
the connections, for input (fig. I, and J).
Doing this will ensure the overall
phase will remain correct. Because
this mode has a low impedance value
of approximately 2 ohms, verify if the
low loading is compatible for your
amplifier.
