[. . . ] Detect the cause and solve the problem, then replace the fuse with another one of the same size and rating. To prevent malfunction of the amplifier and speakers, the protective circuit will cut the power supply to the amplifier (sound will stop) when an abnormal condition occurs. In such a case, switch the power to the system OFF and check the connection of the power supply and speakers. To prevent an electric shock or short-circuit during connection and installation, be sure to disconnect the negative (­) terminal of the battery beforehand. [. . . ] 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. Subwoofer Other than subwoofer Subwoofer Other than subwoofer Subwoofer Other than subwoofer Subwoofer Other than subwoofer Fuse (30 A) 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. External Output If only one input plug is used, do not connect anything to RCA input jack B. The female terminal can be connected to the auto-antenna relay control terminal. If the car stereo does not have a system remote control terminal, connect the male terminal to the power terminal through the ignition switch. Always use the special red battery and ground wire [RD-223], which is sold separately. Fix the wires securely with the terminal screws. Pass the battery wire from the engine compartment to the interior of the vehicle. After making all other connections to the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery. Expose the end of the speaker wires using nippers or a cutter by about 10 mm and twist. [. . . ] After installing the amplifier, confirm that the spare tire, jack and tools can be easily removed. 8 kg (Leads for wiring not included) Maximum power output .
