Connecting the Unit

CAUTION

•Disconnect the negative (–) terminal of the bat- tery to avoid the risk of short-circuit and damage to the unit.

•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, resulting in a short-circuit through the vehicle body.

To prevent damage

•Do not ground the speaker wire directly or con- nect a negative (–) lead wire for several speakers.

•This unit is for vehicles with a 12-volt battery and negative grounding. Before installing it in a recre- ational vehicle, truck or bus, check the battery voltage.

•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.

•Make sure that wires will not interfere with mov- ing parts of the vehicle, such as the gearshift, 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.

•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. But in case of two-channel and other bridge connections, the speaker impedance must be 4 to 8 ohms.

•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.
