Connecting the Unit
Connection Diagram
� 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.

ENGLISH
Connecting the Power Terminal
� Always use the special red battery and ground Special red battery wire [RD-223] (sold separately) After making all other connections at the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery. Fuse (30 A) Ground wire (black) [RD-223] (sold separately) Connect to metal body or chassis. wire [RD-223], which is sold separately. Connect the battery wire directly to the car battery positive terminal (+) and the ground wire to the car body.

CAUTION

� 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. Grommet

Using the Speaker Input
Connect the car stereo speaker output wires to the amplifier using the supplied speaker input connector.
� Do not connect both the RCA input and the speaker input at the same time.

1. Pass the battery wire from the engine compartment to the interior of the vehicle.

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 � for stereo connection, and 4 � to 8 � 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 products may be different colors even if they have the same function. When connecting this product to another product, refer to the supplied manuals of both products and connect cords that have the same function. Front side Car stereo with RCA output jacks
