SECTION 1
SERVICING NOTES
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
CONFIRMING THE OPERATION (E and Indian models)
Please confirm the car audio unit works even if REM output is not
connected when you connect this unit with the car audio unit by

Connections
Cautions
ˎ Before making any connections, disconnect the
ground terminal of the car battery to avoid short
circuits.
ˎ Be sure to use speakers with an adequate
power rating. If you use small capacity speakers,
they may be damaged.
ˎ This is a Phase-Inverted Amplifier.
ˎ Do not connect the ¾terminal of the speaker
system to the car chassis, and do not connect
the ¾terminal of the right speaker with that of
the left speaker.
ˎ Install the input and output cords away from the
power supply wire as running them close
together can generate some interference noise.
ˎ This unit is a high powered amplifier.Therefore,
it may not perform to its full potential if used
with the speaker cords supplied with the car.
ˎ If your car is equipped with a computer system
for navigation or some other purpose, do not
remove the ground wire from the car battery. If
you disconnect the wire, the computer memory
may be erased. To avoid short circuits when
making connections, disconnect the +12V power
supply wire until all the other wires have been
connected.
Parts for Installation and
Connections (Ȑ)
Installation
Before Installation
ˎ Mount the unit either inside the trunk or under a
seat.
ˎ Choose the mounting location carefully so the
unit will not interfere with the normal
movements of the driver and it will not be

(ȓ)
Notes on the power supply
ˎ Connect the +12V power supply wire only after all
the other wires have been connected.
ˎ Be sure to connect the ground wire of the unit
securely to a metal point of the car. A loose
connection may cause a malfunction of the
amplifier.
ˎ Be sure to connect the remote control wire of the
car audio unit to the remote terminal.
ˎ When using a car audio unit without a remote
output on the amplifier, connect the remote input
terminal (REMOTE) to the accessory power supply.
ˎ Use a power supply wire with a fuse attached
(25A).
ˎ All power wires connected to the positive battery
post should be fused within 450 mm of the battery
post, and before they pass through any metal.
ˎ Make sure that the vehicle’s battery wires
connected to the vehicle (ground to chassis)*2are
of a wire gauge at least equal to that of the main
power wire connected from the battery to the
amplifier.
ˎ During full-power operation, a current of more than
25 A will run through the system. Therefore, make
sure that the wires to be connected to the +12V and
GND terminals of this unit are at least 14-Gauge
(AWG-14) or have a sectional area of more than
2mm2.

Notes
ˎ 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.
ˎ 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 capacitor are used in series to
form a circuit, great care must be taken when they
are connected. In such a circuit, there is going to be
an increase in the current which bypasses the
speaker with frequencies around the crossover
frequency.If audio signals continue to be fed into
the crossover frequency area,it may cause the
amplifier to become abnormally hot or the fuse to
blow. 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 situation causing damage to the
amplifier. Therefore, make sure that a speaker is
connected to such a circuit at all times.

Notas
ˎ Al utilizar redes de cruce pasivas en un sistema con
múltiples altavoces, es necesario asegurar que la
impedancia del sistema de altavoces no sea inferior
al valor de impedancia adecuado para esta unidad.
ˎ Al instalar un sistema de 12 decibelios/octava en un
automóvil, hay que tener en cuenta los siguientes
puntos. En un sistema de 12 decibelios/octava
donde se emplea una bobina de choque y un
condensador en serie para formar un circuito, hay
que tener mucho cuidado al conectarlos. En los
circuitos de este tipo, se produce un aumento de la
corriente que pasa por alto el altavoz con
frecuencias próximas a la frecuencia de cruce. Si las
señales de audio siguen enviándose a la zona de
frecuencia de cruce, puede producirse un
sobrecalentamiento anormal del amplificador o
puede fundirse el fusible. Además, si se desconecta
el altavoz, se formará un circuito de resonancia en
serie compuesto por la bobina y el condensador. En
este caso, la impedancia del área de resonancia
disminuirá considerablemente, dando lugar a una
situación de cortocircuito y dañando el altavoz.Por
tanto, es necesario asegurar que haya un altavoz
conectado a un circuito en todo momento.

Notas
ˎ Se utilizar redes de cruzamento passivas num
sistema com várias colunas, é preciso assegurar-se
de que a impedância do sistema de colunas não é
inferior ao valor de impedância adequado para este
aparelho.
ˎ Se instalar um sistema de 12 decibéis/oitava no
automóvel, é preciso ter em atenção os seguintes
pontos. Num sistema de 12 decibéis/oitava em que
se utiliza uma bobina de choque e um condensador
em série para formar um circuito,é preciso ter
muito cuidado ao ligá-los. Neste circuito, vai haver
um aumento na corrente que passa na coluna,
atingindo frequências muito próximas da
frequência de cruzamento. Se continuarem a ser
enviados sinais de áudio para a zona de frequência
de cruzamento, o amplificador pode sobreaquecer
ou pode rebentar um fusível. Além disso, se
desligar a coluna, forma-se um circuito de
ressonância em série composto pela bobina de
choque e pelo condensador.Neste caso, a
impedância na zona de ressonância diminui
drasticamente, dando lugar a uma situação de
curto-circuito e danificando o amplificador. Assim,
tem de haver sempre uma coluna ligada a este
circuito.

Installation
Before Installation
ˎ Mount the unit either inside the trunk or under a
seat.
ˎ Choose the mounting location carefully so the
unit will not interfere with the normal
movements of the driver and it will not be
exposed to direct sunlight or hot air from the
heater.
ˎ Do not install the unit under the floor carpet,
where the heat dissipation from the unit will be
considerably impaired.
Mount the unit (ȑ).
First, place the unit where you plan to install it,
and mark the positions of the 4 screw holes on
the mounting board (not supplied). Then drill a
3mm pilot hole at each mark and mount the unit
onto the board with the supplied mounting
screws. The mounting screws are all 15 mm long,
so make sure that the mounting board is thicker
than 15 mm.
Power connections
Make the terminal connections
(Ȓ).
Pass the wires through the cap, connect the wires,
then cover the terminals with the cap.
Note
When you tighten the screw,be careful not to apply
too much torque* as doing so may damage the
screw.

Make the power connections
(ȓ)
Notes on the power supply
ˎ Connect the +12V power supply wire only after all
the other wires have been connected.
ˎ Be sure to connect the ground wire of the unit
securely to a metal point of the car. A loose
connection may cause a malfunction of the
amplifier.
ˎ Be sure to connect the remote control wire of the
car audio unit to the remote terminal.
Instalación
Antes de realizar la instalación
ˎ Monte la unidad en el interior del maletero o
debajo de un asiento.
ˎ Elija cuidadosamente el lugar de instalación de
forma que la unidad no dificulte las maniobras
normales del conductor y no quede expuesta a
la luz solar directa ni al aire caliente de la
calefacción.
ˎ No instale la unidad debajo de la moqueta del
suelo, en cuyo caso la disipación de calor de la
misma disminuirá considerablemente.
Monte la unidad (ȑ).
En primer lugar, coloque la unidad donde tenga
previsto instalarla y marque sobre la superficie
del tablero de montaje (no suministrado) las
posiciones de los 4 orificios para los tornillos. A
continuación, perfore los orificios con un diámetro
de aproximadamente 3 mm y monte la unidad
sobre el tablero con los tornillos de montaje
suministrados. Ya que la longitud de estos
tornillos es de 15 mm, compruebe que el grosor
del tablero de montaje sea superior a 15 mm.
Conexiones de alimentación
Realice las conexiones de
terminal (Ȓ).
Pase los cables a través de la cubierta,conéctelos
y cubra los terminales con dicha cubierta.
Nota
Al apretar el tornillo, tenga cuidado de no aplicar
demasiada fuerza de torsión*, ya que puede dañarlo.
* El valor de fuerza de torsión debe ser inferior a
a0ŞO
Realice las conexiones de
alimentación (ȓ).
Notas sobre la fuente de alimentación
ˎ Conecte el cable de la fuente de alimentación de
+12V sólo después de haber conectado los otros
cables.
Instalação
Antes de fazer a instalação
ˎ Monte o aparelho dentro da mala ou por baixo
do banco.
ˎ Escolha cuidadosamente o local de montagem
de modo a que o aparelho não interfira com os
movimentos normais do condutor e não fique
exposto à incidência direta dos raios solares
nem ao ar quente proveniente do sistema de
aquecimento.
ˎ Não instale o aparelho por baixo do tapete do
carro porque impedirá a dissipação de calor do
aparelho.
Monte o aparelho (ȑ).
Em primeiro lugar, coloque o aparelho no local
onde o pretende instalar e marque as posições
dos 4 furos para os parafusos na placa de
montagem (não fornecida). Depois,faça um furo
de 3 mm em cada marca e monte o aparelho na
placa, utilizando os parafusos de montagem
fornecidos. Como os parafusos de montagem têm
15 mm de comprimento, deve verificar se a placa
de montagem tem uma espessura superior a
15mm.
Ligações elétricas
Ligue os terminais (Ȓ).
Passe os fios pela capa de proteção, ligue-os e
depois tape os terminais com a capa de proteção.
Nota
Aperte bem o parafuso, mas não com binário
excessivo* para evitar danificá-lo.
* O valor do binário aplicado deve ser inferior a

Notas sobre o fornecimento de corrente
ˎ Ligue o cabo de ligação à corrente de +12V somente
depois de ter ligado todos os outros cabos.
ˎ Ligue o fio de massa do aparelho a um ponto
metálico do automóvel. Uma ligação mal feita
pode avariar o amplificador.
