Notes
¢ When using passive crossover networks in a
multi-speaker system, care must be taken as
the speaker system's impedance should not
be lower than that of the suitable impedance
for this unit.
«When you are installing a 12 decibels/octave
system in your car, the following points must
be considered.
In a 12 decibels/octave
system where both a choke and a capacitor
are used in series to form a circuit, a great
care must be taken when they are connected.
In such a Circuit, there is going to be an
increase in the current which by-passes the
speaker with frequencies at around the

crossover frequency.
If audio signals are
continued to be fed into the crossover
frequency area, it may cause the amplifier to
become abnormally hot or the fuse will be
biown.
Also if the speaker is disconnected, a ~
series-resonant circuit will be formed by the
choke and the capacitor.
In this case, the
impedance in the resonance area will
decrease dramatically resulting in a short
circuit like situation causing a damage to the
amplifier. Therefore, make sure that a
speaker is connected to such a circuit at all
times.

Notes on the power supply
*Connect the +12 volt power supply lead only
after alt the other leads have been connected.
*Be sure to connect the ground lead of the
unit securely to a metal part.of the car, A
loose connection may cause a malfunction
of the amplifier.
*Be sure to connect the remote control lead of
the car audio to the remote lead.
«Use the power supply lead with a fuse
attached (at least 20 amperes).
Level Adjustment
Control
The input level can be varied with this control.
Use it to adjust the input sound level when
using source equipment of other manufacturers.
Turn it to MAX when the output level of the
cassette car audio or CD player seems low.
«Place the fuse in the power supply lead as
close as possible to the car battery.
* During a full-power operation, the current of
more than 20 amperes will run through the
system. Therefore, make sure that the leads
to be connected to the +12 and GND terminals
of this unit respectively must be larger than 14-
Gauge (AWG-14) or with the sectional area of
more than 2 mm?.

| Before Installation
|
*Mount the unit either inside the trank room or
under a seat.
'e Choose the mounting location carefully so that
the unit will not interfere with the normal
driving functions of the driver and it will not be
exposed to direct sunlight or hot air from the
heater.
* Do not install the unit under the floor carpet,
where the heat dissipation from the unit will be
considerably impaired.
Firstly, use the template printed on the back of
the carton to mark the positions of the four
screw holes on the surface of the mounting
board (not supplied). Then drill the holes
whose diameter shoutd be approximately
3 millimeters (mm) and mount the unit onto the
board with the supplied mounting screws.
The
supplied mounting screws are 15 mm long
each. Therefore, make sure that the mounting
board is thicker than 15 mm.
