User manual PIONEER PRS-D4100F

[. . . ] Check the connections of the power supply and speakers if the fuse of the separately sold battery wire or the amplifier fuse blows. 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. [. . . ] Always use the special red battery and ground wire [RD-223], which is sold separately. Fix the wires securely with the terminal screws. Expose the end of the speaker wires using nippers or a cutter by about 10 mm and twist. 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. For four-channel input, connect two speaker input wires with RCA pin cord to RCA input jack A and B. Do not connect anything to RCA input jack B. 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. 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 manuals of both products and connect cords that have the same function. External Output If only one input plug is used, do not connect anything to RCA input jack B. [. . . ] The average current drawn is nearly the maximum current drawn by this unit when an audio signal is input. Use this value when working out total current drawn by multiple power amplifiers. To ensure proper heat dissipation of the amplifier, be sure of the following during installation. --Allow adequate space above the amplifier for proper ventilation. [. . . ]
