User manual PIONEER GM-6300F

[. . . ] Confirm that no parts are behind the panel when drilling a hole for installation of the amplifier. Be sure to protect all cables and important equipment such as fuel lines, brake lines and the electrical wiring from damage. When the unit does not operate properly, contact your dealer or the nearest authorized PIONEER Service Station. If the output is low, even when the volume of the car stereo is turned up, turn these controls clockwise. [. . . ] 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. 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. 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. Do not install in: --Places where it could injure the driver or passengers if the vehicle stops suddenly. --Places where it may interfere with the driver, such as on the floor in front of the driver's seat. Make sure that wires are not caught in the sliding mechanism of the seats, resulting in a short-circuit. Confirm that no parts are behind the panel when drilling a hole for installation of the amplifier. Protect all cables and important equipment such as fuel lines, brake lines and electrical wiring from damage. Install tapping screws in such a way that the screw tip does not touch any wire. This is important to prevent wires from being cut by vibration of the car, which can result in fire. To prevent electric shock, do not install the amplifier in places where it might come in contact with liquids. To ensure proper installation, use the supplied parts in the manner specified. If any parts other than the supplied ones are used, they may damage internal parts of the amplifier, or they may become loose causing the amplifier to shut down. Example of installation on the floor mat or on the chassis Insert the supplied tapping screws (4 × 18 mm) into the screw holes.
