User manual PIONEER GM-D510M

[. . . ] To prevent malfunction of the amplifier and subwoofer, 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 subwoofer. To prevent an electric shock or short-circuit during connection and installation, be sure to disconnect the negative (­) terminal of the battery beforehand. Confirm that no parts are behind the panel when drilling a hole for installation of the amplifier. [. . . ] 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. Connect a subwoofer with a 380 W or larger nominal input and an impedance between 1 and 8 ohms to the amplifier. If the nominal input and impedance are out of the above ranges, the subwoofer may catch fire, emit smoke or become damaged. 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. Ground wire (black) [RD-223] (sold separately) Connect to metal body or chassis. 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. 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. 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. [. . . ] Make temporary connections first and check that the amplifier and the system operate properly. After installing the amplifier, confirm that the spare tire, jack and tools can be easily removed. 9 kg (Leads for wiring not included) Maximum power output .
