• Secure the wiring with cable clamps or adhesive |
tape. To protect the wiring, wrap adhesive tape |
around it where they lie against metal parts. |
• Do not route wires where they will get hot, for |
example where the heater will blow over them. If |
the insulation heats up, it may become damaged, |

handbrake or seat sliding mechanism. |
• Do not shorten any wires. Otherwise the protec- |
tion circuit may fail to work when it should. |
• Never feed power to other equipment by cutting |
the insulation of the power supply wire to tap |
from the wire. The current capacity of the wire |
will be exceeded, causing overheating. |
• Never replace the fuse with one of greater value |
or rating than the original fuse. Use of an improp- |
er fuse could result in overheating and smoke and |
could cause damage to the product and injury |
including burns. |

•If the car stereo is kept on for a long time while the engine is at rest or idling, the battery may go dead. Turn the car stereo off when the engine is at rest or idling.
•If the system remote control wire of the amplifier is connected to the power terminal through the ignition switch (12 V DC), the amplifier will always be on when the ignition is on— regardless of whether the car stereo is on or off. Because of this, the battery could go dead if the engine is at rest or idling.
•Speakers to be connected to the amplifier should conform with the standards listed below. If they do not conform, they may catch fire, emit smoke or become damaged. The speaker impedance must be 2 to 8 ohms for stereo connection, and 4 to 8 ohms for monaural and other bridge connection.
•Install and route the separately sold battery wire as far away as possible from the speaker wires. Install and route the separately sold battery wire, ground wire, speaker wires and the amplifier as far away as possible from the antenna, antenna cable and tuner.
•Cords for this product and those for other prod- ucts may be different colors even if they have the same function. When connecting this product to another product, refer to the supplied Installation manuals of both products and connect cords that have the same function.
