Safety precautions
2WARNING
Take the following precautions to prevent fire and avoid personal injury :
•When extending the battery cable, or ground cable, use 5mm2 (AWG10) or larger automotive grade cable to avoid cable deterioration or damage to the covering.
•Check that no metal objects (coins, tools, etc.) are left inside the unit to avoid short circuits.
•If you smell or see smoke, turn the power off immediately and consult your Kenwood dealer.
•Do not touch the unit during use because the surface of the unit becomes hot and may cause burns if touched.
2CAUTION
Take the following precautions to keep the unit in proper working order.
•Be sure the unit is connected to a 12V DC power supply with a negative ground connection.
•Do not open the top or bottom cover. •Do not install the unit in places it is
exposed to direct sunlight, high heat or humidity, water may splash over it, or dust exists.
NOTE
•If you have difficulty in installing this unit in your vehicle, contact your Kenwood dealer.
Cleaning the unit
•If the surface is dirty, wipe it clean with a silicon cloth or soft dry cloth with the power off.
2CAUTION
Do not use hard cloths or paint thinner, alcohol, or other volatile solvents. These may damage external surfaces or remove indicator characters.

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 cables of the units.
4.Connect the speaker cables and sigma servo feed back cables.
5.Connect the power cable, power control cable and grounding cable following this order.
6.Install the unit in the car.
7.Connect the negative - terminal of the battery.
2CAUTION
•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 cables for shorts, then replace the fuse with one of the same rating.
•Check that no unconnected cables or connectors are touching the car body. Do not remove caps from unconnected cables or connectors to prevent short circuits.
•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 (ø5 × 18 mm)
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.
•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.
•After installing the unit, check to make sure that electrical equipment such as the brake lamps, turn signal lamps and windshield wipers operate normally.
•Install the unit securely in a location that does not interfere with driving.

1Cooling fans
When the internal temperature of the amplifier rises, the cooling fans are activated automatically to drop the temperature. In certain situations, the cooling fans may be operating from the beginning of the amplifier operation.
2 RCA cable ground lead terminal
3 Amplifier A LINE IN terminal
4 Amplifier B LINE IN terminal
5LINE OUT terminal
These jacks output respectively the signals input to amplifiers A and B. They always output the stereo signals regardless of the position of the OPERATION switch.
6 Power control (REMOTE) terminal
7INPUT SENSITIVITY control
Adjust this control according to the pre-out level of the center unit connected to this amp.
The sensitivities of amplifiers A and B can be adjusted independently regardless of the position of the input selector switch.
NOTE
Refer to “Specifications” on the center unit’s instruction manual about the pre-out level.
8INFRASONIC FILTER FREQUENCY switch
When this switch is set to 15 Hz or 25 Hz, frequencies below the setting value will be cut. This serves to get rid of unwanted
vibrations that do not result in sound and improves the speakers’ ability to reproduce sound. Note that the speaker output will automatically be set for monaural (L+R) sound.
9INPUT SELECTOR switch
This switch selects the input method of the signals to be amplified by amplifiers A and B.
•A B position:
Amplifies both of the signals input to amplifiers A and B.
•A position:
Amplifies only signal input amplifier A with both amplifiers A and B.
0OPERATION switch
The amplification methods of the signals input to amplifiers A and B can be selected independently according to the setting of this switch.
•STEREO position:
The amplifier can be used as a stereo amplifier.
•MONO (Lch) position:
Amplifies the signal input from the left side only. Set to this position and make bridged connections to use as a high-power monaural amplifier. (The input right signal is not output.)
!FILTER switch
This switch allows to apply high-pass or low-pass filtering to the speaker outputs.
•HPF (High-Pass Filter) position:
The filter outputs the band of higher frequencies than the frequency set with the HPF FREQUENCY control.
•OFF position:
The entire bandwidth is output without filtering.
•LPF (Low-Pass Filter) position:
The filter outputs the band of lower frequencies than the frequency set with the LPF FREQUENCY control.
The speaker output is automatically turned monaural (L+R) and the bass boost function is activated.
@FREQUENCY control
When the FILTER switch is set to the HPF (High-Pass Filter) or LPF (Low-Pass Filter) position, the threshold frequency can be adjusted with this control.
# Fuse (20 A × 4) $ Battery terminal

^Amplifier A speaker output terminals
&Amplifier B speaker output terminals
SPEAKER OUTPUT terminals
•Stereo Connections:
When you wish to use the unit as a stereo amplifier, stereo connections are used.
The speakers to be connected should have an impedance of 2Ω or greater. When multiple speakers are to be
connected, ensure that the combined impedance is 2Ω or greater for each channel.
•Bridged Connections:
When you wish to use the unit as a highoutput monaural amplifier, bridged connections are used. (Make connections to the LEFT channel (+) and the RIGHT channel (-) SPEAKER OUTPUT terminals.)
The speakers to be connected should have an impedance of 4Ω or greater. When multiple speakers are to be
connected, ensure that the combined impedance is 4Ω or greater.
2CAUTION
The rated input of the speakers should be no less than the maximum output of the amplifier. Otherwise malfunction may result.

2CAUTION
The SIGMA SERVO FEEDBACK terminals should be connected properly. Failure to connect them properly will be the cause of breakdown.
