Information on Disposal of Old Electrical  
and Electronic Equipment (applicable for  
EU countries that have adopted separate  
waste collection systems)  
7 Wiring  
• Take the battery wire for this unit directly from the  
battery. If it's connected to the vehicle’s wiring  
harness, it can cause blown fuses etc.  
• If a buzzing noise is heard from the speakers when  
the engine is running, connect a line noise filter  
(optional) to each of the battery wire.  
• Do not allow the wire to directly contact the edge of  
the iron plate by using Grommets.  
• Connect the ground wire to a metal part of the car  
chassis that acts as an electrical ground passing  
electricity to the battery‘s negative · terminal.  
Do not turn the power on if the ground wire is not  
connected.  
• Be sure to install a protective fuse in the power  
cord near the battery. The protective fuse should  
be the same capacity as the unit’s fuse capacity or  
somewhat larger.  
• For the power cord and ground, use a vehicle type  
(fireproof) power wring cord with a current capacity  
greater than the unit’s fuse capacity. (Use a power  
wiring cord with the range of 14 mm2 (AWG 6) to 21  
mm2 (AWG 4).  
• When more than one power amplifier are going  
to be used, use a power supply wiring wire and  
protective fuse of greater current-handling capacity  
than the total maximum current drawn by each  
amplifier.  
Products with the symbol (crossed-out  
wheeled bin) cannot be disposed as  
household waste.  
Old electrical and electronic equipment  
should be recycled at a facility capable  
of handling these items and their waste  
byproducts. Contact your local authority  
for details in locating a recycle facility  
nearest to you. Proper recycling and waste  
disposal will help conserve resources whilst  
preventing detrimental effects on our  
health and the environment.  
This Product is not installed by the manufacturer of a  
vehicle on the production line, nor by the professional  
importer of a vehicle into an EU Member State.  
Cleaning the unit  
If the front panel gets dirty, turn off the power and  
wipe the panel with a dry silicon cloth or soft cloth.  
CAUTION  
Do not wipe the panel with a hard cloth or a cloth  
dampened by volatile solvents such as paint thinner  
and alcohol. They can scratch the surface of the panel  
and/or cause the indicator letters to peel off.  
7 Speaker Selection  
• The rated input power of the speakers that are  
going to be connected should be greater than the  
maximum output power (in Watts) of the amplifier.  
Use of speakers having input power ratings that  
are less than the output power of the amplifier will  
cause smoke to be emitted as well as damage.  
• The impedance of the speakers that are going  
to be connected should be 2Ω or greater (for  
stereo connections), or 4Ω or greater (for bridged  
connections). When more than one set of speakers  
are going to be used, calculate the combined  
impedance of the speakers and then connect  
suitable speakers to the amplifier.  
To prevent battery rise  
When the unit is used in the ACC ON position without  
turning the engine ON, it depletes the battery. Use it  
after starting the engine.  
Protection function  
The protection function is activated in the following  
situations:  
This unit is equipped with a protection function for  
protecting this unit and your speakers from various  
accidents or problems that can occur.  
When the protection function is triggered, the  
PROTECTION indicator lights and the amplifier stops  
operating.  
• When a speaker wire may be short-circuited.  
• When a speaker output contacts ground.

• Do not install in the below locations;  
(Unstable location, In a location that interferes  
with driving, In a location that gets wet, In a dusty  
location, In a place that gets hot, In a place that  
gets direct sunlight, In a location that gets hit by  
hot air)  
• Do not install the unit under the carpet.  
Otherwise heat build-up occurs and the unit may  
be damaged.  
• Install this unit in a location which allows heat to  
easily dissipate.  
Once installed, do not place any object on top of  
the unit.

• The surface temperature of the amplifier will  
become hot during use. Install the amplifier in a  
place where people, resins, and other substances  
that are sensitive to heat will not come into  
contact with it.  
• This unit has cooling fan to decrease the internal  
temperature. Do not mount the unit in a place  
where the cooling fan and ducts of the unit are  
blocked. Blocking these openings will inhibit the  
cooling of the internal temperature and result in  
malfunction.  
7 Installation procedure  
Since there are large variety of settings and  
connections possible according to applications, read  
the instruction manual well to select the proper  
setting and connection.  
1. Remove the ignition key and disconnect the  
negative · terminal of the battery to prevent short  
circuits.  
2. Set the unit according to the intended usage.  
3. Connect the input and output wires of the units.  
4. Connect the speaker wires.  
• When making a hole under a seat, inside the  
trunk, or somewhere else in the vehicle, check  
that there is nothing hazardous on the opposite  
side such as a gasoline tank, brake pipe, or wiring  
harness, and be careful not to cause scratches or  
other damage.  
5. Connect the power wire, power control wire and  
grounding wire following this order.  
6. Install the installation fittings in the unit.  
7. Attach the unit.  
• Do not install near the dashboard, rear tray, or air  
bag safety parts.  
8. Install the remote controller.  
• The installation to the vehicle should securely  
fasten the unit to a place in which it will not  
obstruct driving. If the unit comes off due to a  
shock and hits a person or safety part, it may  
cause injury or an accident.  
9. Connect the negative · terminal of the battery.  
• After installing the unit, check to make sure that  
electrical equipment such as the brake lamps,  
turn signal lamps and windshield wipers operate  
normally.

CAUTION  
• If sound is not output normally, immediately turn  
power off and check connections.  
• Be sure to turn the power off before changing the  
setting of any switch.  
• If the fuse blows, check wires for shorts, then  
replace the fuse with one of the same rating.  
• Check that no unconnected wires or connectors  
are touching the car body. Do not remove caps  
from unconnected wires or connectors to prevent  
short circuits.  
• Connect the speaker wires to appropriate speaker  
connectors separately. Sharing the negative wire  
of the speaker or grounding speaker wires to the  
metal body of the car can cause this unit to fail.  
• After installation, check that the brake lamps,  
winkers, and wipers work properly.

CAUTION  
Before connecting the remote controller cables, always turn the Bass boost level knob all the way to the left.  
You can control the Bass boost level of the second and subsequent Slave amplifiers simultaneously from the  
Master amplifier.  
The volume level of each amplifier is determined by the setting of the Master amplifier (INPUT SENSITIVITY, boost  
level of the remote controller).  
Setting the Master amplifier  
1. Adjust the INPUT SENSIVITY to the output of the center unit to be connected.  
2. Set the LPF frequency and ISF.  
3. Turn the LINE OUT FILTER switch ON.  
Setting the Slave amplifier  
1. Turn the LINE OUT FILTER switch OFF.  
2. Adjust the INPUT SENSIVITY.  
• To adjust the Slave amplifier to the same volume as the Master amplifier, adjust the INPUT SENSIVITY to 0.2 V  
(max.).
