Composition of Manual
This manual applies to the GM-X552,
GM-X352 and GM-X252. However, the
illustrations show the GM-X552.
WARNING
· Always use the special red battery and ground
wire [RD-223], which is sold separately. Connect
the battery wire directly to the car battery positive
terminal (+) and the ground wire to the car body.
· Do not touch the amplifier with wet hands.
Otherwise you may get an electric shock. Also, do
not touch the amplifier when it is wet.
· For traffic safety and to maintain safe driving
conditions, keep the volume low enough so that
you can still hear normal traffic sound.
· Check the connections of the power supply and
speakers if the fuse of the separately sold battery
wire or the amplifier fuse blows. Detect the cause
and solve the problem, then replace the fuse with
another one of the same size and rating.
· To prevent malfunction of the amplifier and
speakers, the protective circuit will cut the power
supply to the amplifier (sound will stop) when an
abnormal condition occurs. In such a case, switch
the power to the system OFF and check the
connection of the power supply and speakers.
Detect the cause and solve the problem.
· Contact the dealer if you cannot detect the cause.
· To prevent an electric shock or short-circuit
during connection and installation, be sure to
disconnect the negative () terminal of the battery
beforehand.
· Confirm that no parts are behind the panel when
drilling a hole for installation of the amplifier. Be
sure to protect all cables and important equipment
such as fuel lines, brake lines and the electrical
wiring from damage.

Selecting fine audio equipment such as the unit you've just purchased is only the start of your
musical enjoyment. Now it's time to consider how you can maximize the fun and excitement your
equipment offers. This manufacturer and the Electronic Industries Association's Consumer
Electronics Group want you to get the most out of your equipment by playing it at a safe level.
One that lets the sound come through loud and clear without annoying blaring or distortion--and,
most importantly, without affecting your sensitive hearing.
Sound can be deceiving. Over time your hearing "comfort level" adapts to higher volumes of
sound. So what sounds "normal" can actually be loud and harmful to your hearing. Guard against
this by setting your equipment at a safe level BEFORE your hearing adapts.
To establish a safe level:
· Start your volume control at a low setting.
· Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.
Once you have established a comfortable sound level:
· Set the dial and leave it there.
Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all,
we want you listening for a lifetime.
We Want You Listening For A Lifetime
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since
hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the
Electronic Industries Association's Consumer Electronics Group recommend you avoid prolonged
exposure to excessive noise. This list of sound levels is included for your protection.

Mode d'emploi
To prevent damage
· Do not ground the speaker wire directly or con-
nect a negative () lead wire for several speakers.
· This unit is for vehicles with a 12-volt battery and
negative grounding. Before installing it in a recre-
ational vehicle, truck or bus, check the battery
voltage.
· If the car stereo is kept on for a long time while
the engine is at rest or idling, the battery may go
dead. Turn the car stereo off when the engine is at
rest or idling.
· If the system remote control wire of the amplifier
is connected to the power terminal through the
ignition switch (12 V DC), the amplifier will
always be on when the ignition is on-- regardless
of whether the car stereo is on or off. Because of
this, the battery could go dead if the engine is at
rest or idling.
· Speakers to be connected to the amplifier should
conform with the standards listed below. If they
do not conform, they may catch fire, emit smoke
or become damaged. The speaker impedance must
be 2 to 8 ohms for stereo connection, and 4 to 8
ohms for monaural and other bridge connection.
· Install and route the separately sold battery wire
as far away as possible from the speaker wires.
Install and route the separately sold battery wire,
ground wire, speaker wires and the amplifier as
far away as possible from the antenna, antenna
cable and tuner.
· Cords for this product and those for other prod-
ucts may be different colors even if they have the
same function. When connecting this product to
another product, refer to the supplied Installation
manuals of both products and connect cords that
have the same function.
Connection Diagram
Connecting the Unit
CAUTION
· Disconnect the negative () terminal of the battery
to avoid the risk of short-circuit and damage to
the unit.
· Secure the wiring with cable clamps or adhesive
tape. To protect the wiring, wrap adhesive tape
around it where they lie against metal parts.
· Do not route wires where they will get hot, for
example where the heater will blow over them. If
the insulation heats up, it may become damaged,
resulting in a short-circuit through the vehicle
body.
· Make sure that wires will not interfere with mov-
ing parts of the vehicle, such as the gearshift,
handbrake or seat sliding mechanism.
· Do not shorten any wires. Otherwise the protec-
tion circuit may fail to work when it should.
· Never feed power to other equipment by cutting
the insulation of the power supply wire to tap
from the wire. The current capacity of the wire
will be exceeded, causing overheating.

Connecting the Speaker wires
The speaker output mode can be two-chan-
nel (stereo), one-channel (mono), or three-
channel (stereo + mono). Connect the
speaker leads to suit the mode according to
the figures shown below.
· Do not connect both the RCA input and the
speaker input at the same time.
Two-channel mode (stereo)
One-channel mode (mono)
Three-channel mode (stereo + mono)
The power amplifier is basically a two-
channel/one-channel bridgeable amplifier,
but three channels can be achieved by
combining the stereo and mono modes
using inductors and capacitors.
Three-channel mode, two-way system
Three-channel mode, three-way system
· Inductors (L1 and L2 in the diagrams)
act as low-pass filters. Capacitors (C1
and C2 in the diagrams) act as high-pass
filters. Inductors (L) are used for the
woofer/subwoofer, and capacitors (C)
are used for the high/mid-high.
· Remember when bridging an amplifier it
will see only half of the original speaker
impedance. Therefore, you must use
speakers that have ratings of 4 ohms or
higher. If you use speakers that have
lower impedance ratings it may cause
damage to the amplifier.
· When the inductors and capacitors are
connected to the speaker wires, secure or
solder them so they cannot be pulled
loose. Tape or use heat shrink on the
joints to prevent short circuits.

Setting the Filter Constant
Low-pass filter (for subwoofer/woofer):
6 dB/octave
High-pass filter (for mid/mid-high):
6 dB/octave
Band-pass filter (combination of low-pass
filter and high-pass filter for mid-
bass/mid): 6 dB/octave
· A multi-channel system can be set up using a
combination of filters. The inductance (L) and
capacitance (C) will determine the frequency (fc)
that the speaker will reproduce. Refer to the chart
below to determine the components required.
· Use the capacitors specified. Non-polarized capac-
itors rated at over ±25 V should be used for C1
and C2 in the diagram. Because of the voltage
output of the amplifier, it is very important to use
non-polarized capacitors rated at or over 25 V.
This will prevent a safety hazard.

de votre ouïe.
Pour établir un niveau sûr:
·
Démarrer votre commande de volume à un réglage bas.
·
Augmentez lentement le son jusqu'à ce que vous l'entendiez confortablement et clairement,
sans distorsion.
Lorsque vous avez établi un niveau sonore confortable:
·
Réglez le cadran et laissez-le tel quel.
En prenant une minute pour faire cela, vous pourrez éviter des dommages ou des pertes de sen-
sibilités d'écoute dans le futur. Après tout, nous voulons que vous écoutiez pendant toute votre vie.
Nous voulons que vous écoutiez pendant toute votre vie
Utilisé avec sagesse, votre nouvel équipement sonore sera une source de plaisir pendant toute

Composition du manuel
Ce manuel s'applique aux modèles

Cependant, les figures ne montrent que le
modèle GM-X552.
AVERTISSEMENT
· Utilisez le faisceau de câbles de liaison à la
batterie (un câble rouge et un câble de masse) qui
est vendu séparément [RD-223]. Reliez le câble
rouge à la borne positive (+) de la batterie et le
câble de masse à la carrosserie du véhicule.
· Ne touchez pas l'amplificateur quand vous avez
les mains mouillées, faute de quoi vous risquez de
ressentir une secousse électrique. Pareillement, ne
touchez pas l'amplificateur s'il est mouillé.
· Pour votre sécurité et celles des autres usagers de
la route, maintenez le niveau d'écoute à une
valeur telle que les bruits de la circulation
demeurent nettement perceptibles.
· Si le fusible monté sur le câble de liaison à la
batterie, câble qui est vendu séparément, a grillé
ou bien s'il en est ainsi de celui de l'amplificateur,
vérifiez soigneusement toutes les connexions
d'alimentation. Recherchez la cause de l'anomalie
puis corrigez-la; enfin, remplacez le fusible grillé
par un fusible de même taille et de même calibre.
· Pour éviter d'endommager l'amplificateur et les
haut-parleurs, le circuit de protection coupe
l'alimentation de l'amplificateur (les sons ne sont
plus émis) dès que survient une situation
anormale. Dans ce cas, mettez l'ensemble des
appareils hors tension et contrôlez les liaisons
entre l'amplificateur et les haut-parleurs. Le cas
échéant, recherchez la cause de l'anomalie et
corrigez-la.
· Consultez le revendeur si vous n'êtes pas en
mesure de résoudre le problème qui se pose à
vous.
· Pour éviter toute secousse électrique et tout risque
de court-circuit au cours des opérations de
raccordement et d'installation, n'oubliez pas de
débrancher le câble relié au pôle négatif de la
batterie () avant d'effectuer quelque opération
que ce soit.
· Avant d'effectuer un perçage requis par
l'installation de l'amplificateur, assurez-vous que
vous pouvez le faire sans danger pour les câbles,
canalisations, flexibles, etc., qui sont placés
derrière le panneau que vous devez percer.
