Safety precautions
2WARNING
To prevent injury or fire, take the following precautions:
•When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with a 5 mm² (AWG 10) or more to prevent wire deterioration and damage to the wire coating.
•To prevent a short circuit, never put or leave any metallic objects (such as coins or metal tools) inside the unit.
•If the unit starts to emit smoke or strange smells, turn off the power 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
To prevent damage to the machine, take the following precautions:
•Be sure the unit is connected to a 12V DC power supply with a negative ground connection.
•Do not open the top or bottom covers of the unit.
•Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing.
•When replacing a fuse, only use a new one with the prescribed rating. Using a fuse with the wrong rating may cause your unit to malfunction.
•To prevent a short circuit when replacing a fuse, first disconnect the wiring harness.
NOTE
•If you experience problems during installation, consult your Kenwood dealer.
•If the unit does not seem to be working right, consult your Kenwood dealer.
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.
2CAUTION
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.
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
There is a Protection function installed in the unit to protect the unit and speakers from various problems. When Protection operates, the indicator informs you of the condition. (Refer to page 5)

2CAUTION
•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.
•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.

1 FILTER switch |
4 OPERATION 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 FILTER 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 FILTER FREQUENCY control.
2FILTER FREQUENCY control
Sets the cutoff frequency when the FILTER switch is set to LPF or HPF.
3INPUT SENSITIVITY control
Set this control according to the pre-output level of the center unit connected with this unit, or
to the maximum power output of the genuineaccessory car stereo.
Use the diagram on the right as a guide.
NOTE
This switch is used to select the operation mode of the amplifier.
•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.)
For the pre-output level or the maximum power output, refer to the <Specifications> in the instruction manual of the center unit.

5Power indicator
When the power is turned on, the Power indicator lights.
If the Power indicator does not light when the power is turned on, the protection function may be activated. Check whether there is any indication of trouble.
■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 Power indicator goes off and the amplifier stops operating.
•When a speaker wire may be short-circuited.
•When a speaker output contacts ground.
•When the unit malfunctions and a DC signal is sent to the speaker output.
•When the internal temperature is high and unit won’t operate.
•When a ground wire of the center unit (cassette receiver, CD receiver, etc.) or this unit is not connected to a metal part serving as an electrical ground passing electricity to the battery's negative - terminal.
