Installation procedure

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 wires.

5. Connect the power wire, power control wire and grounding wire following this order.

6. Install the unit in the car.

7. Connect the negative - terminal of the battery.

To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery’s positive terminal.

• 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 cables or connectors are touching the car body. Do not remove caps from unconnected cables 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.

■ Speaker level input terminals (!)

• The genuine-accessory car stereo shall have a maximum power output of no more than 40 W.

•Do not connect the speaker output leads from a power amplifier (Optional) to the speaker level input terminals of this unit, for this may cause malfunction or damage.

• Do not connect cables and leads to both RCA cable input jacks and the speaker level input terminals simultaneously, for this may cause malfunction or damage.

• Connect the power control lead to a power supply which can be turned ON/OFF by the ignition key switch (ACC line). With this connection, shock noise may be generated when the power of the genuine-accessory car stereo is switched ON/OFF.

■ Power terminal (234)

Connect to their respective terminals the power supply wire, and ground wire, all of which pass through the associated terminal cover. Once the connections are complete, place the cover on the terminal section.

■ Accessories

Installation

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.

• 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.

Safety precautions

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 3mm2(AWG12) 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.

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.

• 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.

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.

■ 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 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 a diameter of 3 mm2(AWG 12) or greater.)

• 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.

■ 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.

■ Tri-mode

Principle of Tri-mode

Method of frequency band division using a coil and capacitor ... in case of 6dB/oct. slope Coil (L): Passes low frequencies and blocks high frequencies. (Low pass) Capacitor (C): Passes high frequencies and blocks low frequencies. (High pass)

Example:

When it is required to set a crossover frequency of 120 Hz using speakers with an impedance of 4 ohms. fc=Cut of Frequency (Hz) R=Speaker Impedance (Ω)

• If you wish to bridge-connect a speaker, the speaker impedance must be no less than 4 ohms. Connecting a speaker with an impedance lower than 4 ohms may damage the unit.

• Be sure to connect capacitors to speakers to which high frequencies will be passed. Failure to do so will result in a drop of the combined impedance with the subwoofer.

• Ensure that the withstand voltage and current ratings of the capacitors (C) and coils (L) are sufficient.

● 車內原裝立體聲的最大輸出功率不得大於 40 瓦。

● 不要將揚聲器的輸出引線從功率放大器（選購件）連接到本機的揚聲器的輸入端子。否則，將造成誤動作或損壞。

● 不可同時連接纜線和引線到 RCA 纜線輸入端子及揚聲器輸入端子。否則，將造成誤動作或損壞。

● 將電源控制導線連接到起動鑰匙可以控制開關（ACC 線）的電源上。在這樣連接的場合，當車內原裝立體聲電源開關時，可能產生沖擊噪音。

三模式的原理

使用線圈及電容進行頻率區分的方法 ... 在 6dB/ oct. 的條件下

線圈 (L): 讓低頻通過，阻塞高頻（低頻通過）電容 (C): 讓高頻通過，阻塞低頻（高頻通過）

實例

當使用的揚聲器的阻抗為 4 歐姆，所需要的交叉頻率為 120 Hz 時。

fc= 阻斷頻率 (Hz) R= 揚聲器阻抗 (Ω)
