Safety precautions

WARNING

To prevent injury or fire, take the following

precautions:

• Mounting and wiring this product requires skills and

experience. For safety’s sake, leave the mounting and

wiring work to professionals.

• When extending the ignition, battery, or ground wires,

make sure to use automotive-grade wires or other wires

with the range of 5 mm (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.

CAUTION

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.

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.

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 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.

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. (Use a power wiring cord

with the range of 5 mm (AWG 10) or more.)

• 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.

7 Speaker selection

• Using speakers with smaller input ratings than the

amplifier’s output power would result in smoke

generation or equipment failure.

• The impedance of the speakers that are going to

be connected should be 2 or greater (for stereo

connections), or 4 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.

安全注意事项

警告

为了防止受伤和火灾，请遵守下列注意事项。

• 安装本产品和连接导线需要一定的技能和经验。为了保证安

全，应请专业人员完成安装和连接导线作业。

• 当延长蓄电池导线和接地导线时，请使用车辆用导线或

5mm2（AWG 10）以上的导线，以防止导线劣化和被覆面

的损伤。

• 为了防止短路等事故，请勿将金属物品（硬币，工具等）掉

落在装置中。

• 万一装置冒烟或有异味时，请立即关闭电源，并与建伍经销

商洽谈。

• 在使用中请尽量不要接触装置表面。因为装置在使用中表面

发热会烫伤人体。

注意

为了防止装置发生故障，请遵守下列注意事项，正确操作和

使用。

• 请以负接地线的12V直流电源向本装置供电。

• 请勿打开顶部和底部的盖子。

• 请勿将本装置安装在曝露于直射阳光，高温或高湿，水可

能飞溅的或有灰尘的地方。

• 更换保险丝时，请更换规定容量相同的保险丝，如使用不

同容量的保险丝，可能会造成装置的故障。

• 更换保险丝时，为了防止短路事故，请先拔下电源线束再进

行更换。

注

• 安装有困难时，请与建伍经销商洽谈。

• 如果仍不能恢复正常时，请与建伍经销商洽谈。

装置的保养

如果外表污脏时，请关闭电源，使用干燥的硅布或柔软的布

匹擦拭。

注意

请勿使用硬布或涂料稀释剂，酒精等挥发性溶剂，以免损坏

外表面或将所附指示字符擦掉。

防止蓄电池全部放电

当本机在ACC ON位置使用而不开动发动机时，将消耗蓄电池

的电量。请在开动了发动机之后使用。

保护功能

在以下场合中保护功能被激活

本机装有保护功能，可以保护本机以及扬声器不会受到可能

发生的各种意外事故的损害。

当保护功能被触发时，电源指示灯将熄灭，放大器也停止工

作。

• 当扬声器缆线短路时。

• 当扬声器的输出接地时。

• 当本机出现误动作，有 DC（直流）信号传送到扬声器输出

端时。

• 内部高温不能动作时。

7 接线

• 请将本机的蓄电池连接线直接与蓄电池连接。如果与汽车

的配线束连接，将产生烧毁保险丝等故障。

• 如果发动机运转时从扬声器中发出噪音，可以在蓄电池的每

根连线上加一个线路噪音滤波器（选购件）。

• 使用保护套，以防缆线直接接触铁板的边缘。

• 将接地线连接到车架的金属部位，车架起到车辆电气接地的

作用，将电流传递到蓄电池的负极·。如果接地线没有连

接就不要打开电源开关。

• 应务必在蓄电池附近的电源连接线上设置保险丝。保险丝

的规格应该与本机的保险丝容量相同或者略大。

• 对于电源连接线和接地线，请使用汽车用（防火）电源连接

线。（请使用截面积为5mm2（AWG 10）或者以上的电源

连接线。）

• 当使用多个功率放大器时，电源导线的电流容量及保险丝的

容量要大于各个放大器的使用电流之和的最大值。

7 扬声器选择

• 使用输入额定值比放大器输出功率小的扬声器将会导致冒烟

或设备故障。

• 所连接的扬声器的阻抗必须为 2 欧姆或更高（立体声连接

时）；或者 4 欧姆或更高（桥接连接）。当使用一组扬声

器时，必须在计算扬声器的总阻抗之后，再连接合适的扬

声器。

Connection / 连接

WARNING Remove the ignition key and disconnect the negative · terminal of the

battery to prevent short circuits.

警告拔取点火钥匙，拆掉蓄电池负极端子，以防短路。·

WARNING

Particular attention must be given to making good

electrical contact at the amplifier-output and speaker

terminals.

Poor or loose connections can cause sparking or

burning at the terminals because of the very high

power that the amplifier can deliver.

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, turn signal

lamps and windshield wipers work properly.

警告

要特别注意放大器的输出口和扬声器端子处有良好的电气

接触。

因为放大器要发出非常高的功率，松弛或不良的连接可能

在端子处产生火花甚至燃烧。

注意

· 如果声音输出不正常，应立即关断电源并检查连接是否正

确。

· 在变更开关的设定时，必须首先切断电源。

· 当保险丝熔断后，要检查缆线是否有短路，并更换上相同

规格的保险丝。

· 检查是否有尚未连接的缆线或与车体相接触的端头。未

连接缆线及其端部的保护帽不可拆掉，以防短路。

· 扬声器的缆线要分别连接到各自的端子。共用扬声器的

负极缆线或将扬声器端子接地到汽车的金属部分，都会导

致本机停止工作。

· 安装之后，请检查汽车的刹车灯、方向指示灯、雨刷等是

否正常动作。

WARNING

To prevent fire caused by a short in the wiring,

connect a fusible link or breaker nearby the

battery’s positive terminal.
