Installation procedure  
• Connect the speaker cables to appropriate  
speaker connectors separately. Sharing the  
negative cable of the speaker or grounding  
speaker cables 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.  
Installation  
Self-tapping screw  
Air inlet  
Cooling fan  
Air inlet  
Installation board, etc.  
(thickness : 15 mm or more)  
• Since the power amplifier has no parts which require operation, it can be installed at a position  
away from the driver’s seat without any hindrances.  
As generally accepted positions for its installation, places such as inside the trunk, etc. can be  
considered.  
• Use the extension cables. (Optional.)

2CAUTION  
• 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 fans to decrease the internal temperature. Be careful not to block the  
cooling fan openings when installing the unit. Blocking these openings will inhibit the cooling of  
the internal temperature and result in malfunction.  
• 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.  
• Do not install near the dashboard, rear tray, or air bag safety parts.  
• 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.  
• After installing the unit, check to make sure that electrical equipment such as the brake lamps,  
turn signal lamps and windshield wipers operate normally.

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.  
• Use speakers that have an impedance of 2or greater. 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.

2WARNING  
To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery’s  
positive terminal.  
Wiring  
• 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 cable.  
• Do not allow the cable to directly contact the edge of the iron plate by using Grommets.  
• Connect the ground cable 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  
cable is not connected.  
• Please be sure to install a protective fuse in the power cable, near the battery. Use a fuse which  
has a capacity about 10A higher than the capacity of the fuse in the unit.  
• For the power cable and the earth cable, use (flame-resistant) power wiring cables for in-car use.  
For the power cable, use a power wiring cable with a current capacity about 10A higher than the  
capacity of the protective fuse (about 20A higher than the capacity of the fuse in the unit).  
• When more than one power amplifier are going to be used, use a power supply wiring cable and  
protective fuse of greater current-handling capacity than the total maximum current drawn by each  
amplifier.

Sigma servo feed back  
The sound reproduced through conventional amplifiers is distorted due to the  
counterelectromotive force produced in the oscillating system of the speaker. The  
counterelectromotive force is particularly high with the woofer which requires a large drive  
mass.The sigma servo connection reduces distortion caused by the counterelectromotive force  
by including the circuit up to the speaker terminals in the negative feedback loop. This makes it  
possible to drive speakers with more fidelity to the input signals and create a sharp bass sound  
image with few feeling of noise interference.  
NOTE  
The speaker cables and sigma servo cables should be distributed along the same paths.  
2CAUTION  
• The extension of the negative feedback loop to include the speaker terminals makes it  
necessary to connect the sigma servo terminals correctly. Incorrect connection may result in  
sound degradation or other malfunction. If sound is not reproduced normally, check the  
connection of the sigma servo terminals, etc.  
• If the Sigma servo terminals are not connected, the sound may fluctuate or noise may occur.  
Be sure to connect the Sigma servo terminals correctly.  
• When connecting speakers in a parallel configuration, use speakers with an impedance of 4  
ohms or more. Connecting speakers with smaller impedance than 4 ohms will cause  
malfunction.  
• The rated input of the speakers connected to this unit should be no less than the maximum  
output of the amplifier. Otherwise malfunction may result.  
Be specially careful in this when connecting speakers in a parallel configuration.

Connection  
The acoustic properties of vehicle compartment tend to  
cause oscillation due to resonance or unclearness of  
sound due to standing waves at certain frequencies.  
The band reject filter can solve the problems of  
resonance or unclear sound with minimum influence on  
the sound quality because it eliminates only the  
frequencies causing resonance or standing waves.  
0 dB  
Frequency  
Adjustment method:  
The band reject filter cuts only the limited frequencies to minimize influence on the sound  
quality. Therefore, its effect cannot be obtained unless the cutoff frequencies are set  
accurately to the frequencies causing resonance and standing waves. The band reject filter can  
be adjusted according to what you feel through your ears, but we recommend the use of a  
signal generator or a spectrum analyzer with a fine frequency measurement capability for the  
adjustment.  
• Adjustment using a signal generator:  
Output a sine wave, vary its frequency to find the frequencies at which the vehicle compartment  
resonates or volume increases (standing waves occur), and set the BAND REJECT FREQUENCY  
control to the position with which the resonance and standing waves disappear.  
• Adjustment using a spectrum analyzer:  
Output white noise (sound in which all frequencies are at a certain level), find the peak  
frequency observed on the spectrum analyzer, and set the BAND REJECT FREQUENCY control  
to the position with which the peak observed on the spectrum analyzer disappears.
