Connecting the Unit

! CAUTION
• Disconnect the negative (–) terminal of the battery 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.
• Make sure that wires will not interfere with moving parts of the vehicle, such as the gearshift,
handbrake or seat sliding mechanism.
• Do not shorten any wires. Otherwise the protection 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
improper fuse could result in overheating and smoke and could cause damage to the
product and injury including burns.
! CAUTION:
To prevent damage and/or injury
• Do not ground the speaker wire directly or connect 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 recreational 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.
• 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 products 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.
