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
2
5mm
（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5mm
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。
2
