Connecting the Units
Note:
This unit is for vehicles with a 12-volt
battery and negative grounding. Before
installing it in a recreational vehicle,
truck, or bus, check the battery voltage.
To
avoid
shorts
in
the
electrical
system,
be sure to disconnect the battery ©
cable before beginning installation.
Refer to the owner's manual for details
on connecting the various cords of the
power
amp
and
other
units,
then
make
connections correctly.
Secure the wiring with cable clamps or
adhesive tape. To protect the wiring,
wrap
adhesive
tape
around
them
where
they lie against metal parts.
Route
and
secure
all
wiring
so
it
cannot
touch
any
moving
parts,
such
as
the
gear
shift,
handbrake,
and
seat
rails.
Do
not
route
wiring
in
places
that
get
hot,
such
as
near
the
heater
outlet.
If
the
insulation
of
the
wiring
melts
or
gets
torn,
there
is
a
danger
of
the
wiring
short-circuiting
to
the
vehicle
body.
Don’t
pass
the
orange
lead
through
a
hole
into
the
engine
compartment
to
connect
to
the
battery.
This
will
damage
the
lead
insulation
and
cause
a
very
dangerous
short.
Do
not
shorten
any
leads.
If
you
do,
the
protection
circuit
may
fail
to
work
when
it
should.
Never feed power to other equipment
by cutting the insulation of the power
supply lead of the unit and tapping into
the lead. The current capacity of the
lead will be exceeded, causing over
heating.
When replacing fuse, be sure to use
only fuse of the rating prescribed on the
fuse holder.
When the 2-speaker system is employed
in the PRO mode, use the rear outputs
(middle/bass) of this unit. Otherwise,
auto-equalization cannot be carried out.
When the 2-speaker system is employed
in the STD mode, use the front outputs
of this unit. Otherwise, auto-equaliza-
tion cannot be carried out and the
effects of the sound field control cannot
be obtained.

Installation
Note:
Before finally installing the unit, connect
the wiring temporarily and make sure it
is all connected up properly and the unit
and the system work properly.
Use
only
the
parts
included
with
the
unit
to
ensure
proper
installation.
The
use
of
unauthorized
parts
can
cause
malfunctions.
Consult with your nearest dealer if
installation
requires
the
drilling
of
holes
or other modifications of the vehicle.
Install
the
unit
where
it
does
not
get
in
the driver's way and cannot injure the
passenger
if
there
is
a
sudden
stop,
like
an emergency stop.
When mounting this unit, make sure
none
of
the
leads
are
trapped
between
this
unit
and
the
surrounding
metalwork
or fittings.
Before
drilling
any
mounting
holes
always
check
behind
where
you
want
to
drill
the
holes.
Do
not
drill
into
the
gas
line,
brake
line,
electrical
wiring
or
other
important
parts.
It
is
extremely
dangerous
to
allow
the
Control
Unit
lead
to
become
wound
round
the
steering
column
and
shift
lever.
Install
the
Control
Unit
in
such
a
way
that
it
will
not
obstruct
driving.
Do
not
mount
Hide-away
unit
near
the
heater
outlet,
where
it
would
be
affected
by
heat,
or
near
the
doors,
where
rainwater
might
splash
onto
it.
lf Hide-away unit is installed in the
passenger compartment, anchor it
securely so it does not break free while
the car is moving, and cause injury or
an accident.
If Hide-away unit is installed under a
front seat, make sure it does not
obstruct seat movement. Route all leads
and cords carefully around the sliding
mechanism so they do not get caught or
pinched in the mechanism and cause a
short circuit.
If you are not going to affix the front
panel to the mounting base with a
screw (so you can detach the front
panel), be sure that the control unit is
mounted
at
an
angle
no
greater
than
30°
from
level.
If
it
is
attached
at
an
angle
greater
than
30°
the
front
panel
may
fall
out
of
the
mount,
or
the
detach
feature
may not work correctly. (Fig. 7)

Precautions
Do not touch the contacts on the front
panel or on the mounting base, since
this may result in poor electrical
contact.
If
dirt
or
other
foreign
sub-
stances get on the contacts, wipe them
with
a
clean,
dry
cloth.
(Fig.

Do not touch the pin located above the
mounting base contacts.
This pin is a switch that determines
whether or not the front panel is
currently
mounted.
If
you
touch
this
pin,
and accidentally bend or break it, the
unit will not be able to function.
Fig. 23
Fig. 22
Precautions When Handling the
Front Panel
Do not leave the front panel in any area
exposed to high temperatures or direct
sunlight.
Do not drop the front panel or other-
' wise subject it to strong impact.
Do not allow such volatile agents as
benzine, thinner, or insecticides to
come into contact with the surface of
the front panel.
Never try to disassemble the front
panel.
Stereo/monaural Mode of
Sub-woofer Gz@o
The sub-woofer outputs of this unit has
been set to stereo (2 channels for the left
and right). In case you can use only one
sub-woofer due to the limited space or if
you want to output the same monaural
audio from the left and right sub-woofers,
it is possible to switch the sub-woofer
outputs to monaural.
While holding button [4] and (F1) of
buttons [9] depressed, switch the car
ignition switch from OFF to ACC or ON.
This switches the sound alternately
between stereo and monaural.

When this unit is connected to the head
unit, the volume, balance and fader can be
adjusted with this unit. Before operating
this unit, set the head unit as follows.
1. Press the (-) side of buttons [1] to set
the volume of the unit to “V 0”.
2. Set the volume of the head unit to
“VOL 23”.
3. Set the fader and balance of the head
unit to center position.
* To adjust the volume, fader and balance
on the head unit, refer to the Owner's
Manual that accompanies the head unit.

Note:
When the head unit volume is excessive
(excessive input to the unit), “CLIP” [16]
will be indicated on the display as a
warning. In this case, turn the volume
on the.head unit down to the point
where “CLIP” is no longer displayed.
When you feel a distortion in the sound
even though “CLIP” is not indicated on
the display, turn the volume on the
head unit down.
The volume’s set point is not indicated
on the display when you adjust the
volume on the head unit by tuning the
volume control. In this case, set the
volume control on the head unit to the
position illustrated below, in accordance
with step 2. (Fig. 25)

Adjusting Network
The network function built into this unit
divides audio signal into frequency ranges
so that each range can be reproduced
though the exclusive speaker unit for that
range.
Adjustment Items
The adjustments possible with the network
function are as follows. Adjust the
following items according to the reproduce
frequency bands and properties of the
speaker units.

@ Reproduce Frequency Band
The
reproduce frequency
band
of
each
speaker unit can be set by adjusting the
cutoff frequencies of the high-pass filter
(HPF) and low-pass filter (LPF).
* The HPF is a filter which passes high
frequencies by cutting off the lower
frequencies (range) than the set
frequency.
* The LPF is a filter which passes low
frequencies by cutting off the higher
frequencies (range) than the set
frequency.

@) Level
The difference in reproduce levels between
speaker units can be corrected.
3) Slope
The continuity between the sounds from
different speaker units can be adjusted by
adjusting the slopes (inclination of
attenuation of the filtering characteristics)
of the HPF and LPF.
@ Phase
The phase of each speaker unit (only the
subwoofer in case of STD mode) can be
switched between normal and reverse for
input signal. If the continuity between the
sounds from different speaker units is
poor, try switching their phases. This may
sometimes improve the sound continuity.
Tips for Network Adjustment
Cutoff Frequency
In case the subwoofer are installed on
the rear tray, setting a high cutoff
frequency for “LOW” or “SW” results in
separation of bass sound which would
be heard from the backward position. It
is recommended to set the cutoff
frequency of “LOW” or “SW” to no
more than 100 Hz. (“LOW” is set in PRO
mode and “SW” is set in STD mode.)
Git) ~The speakers used as the
middle/bass and high-range units
usually have lower allowable input
levels than the sub-woofer.
Therefore, do not set the cutoff
frequencies of “MID1” and/or “HIGH”
too low, for this will cause the strong
signal of the low range to be input to
these speakers and may result in their
damage.
Slope
lf the absolute value of the slope is set
too small (gentler), the frequency
characteristics may be affected due to
the interference with the speaker units
with adjacent reproduce frequency
ranges.
If the absolute value of the slope is set
too large (sharper), the sound continuity
between speaker units will be
deteriorated and the sound seems to be
separated.
If the slope is set to 0 dB/oct. the filter is
defeated because the audio signal
bypasses the filter circuit.
