User manual PIONEER GM-5200

[. . . ] Otherwise you may get an electric shock. Also, do not touch the amplifier when it is wet. For traffic safety and to maintain safe driving conditions, keep the volume low enough so that you can still hear normal traffic sound. Check the connections of the power supply and subwoofer if the fuse of the separately sold battery wire or the amplifier fuse blows. [. . . ] If sound output is cut, the gain control of this unit may be improperly set. To ensure continuous sound output at increased volume of the head unit, set the gain control of the amplifier to a proper position according to the preout maximum output level of the head unit. There is no need to decrease the volume of the head unit and too much output is controlled. 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. 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. 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. However, since excessively tightening the terminal screw of the System remote control has the risk of damaging the wire, be careful not to tighten excessively by observing the status of the wire when tightening. Relationship between the gain of the amplifier and the output power of the head unit Power Normal gain Equal power Power Maximum gain 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. Ground wire (black) [RD-228] (sold separately) Connect to metal body or chassis. If you raise the gain of the amplifier to an improper level, only distortion is increased and the power increases only slightly. Car stereo with RCA output jacks Jack for the bass boost remote control Connect this jack and the bass boost remote control with the bass boost remote control wire. We recommend that you use the special red battery and ground wire [RD-228], which is sold separately. The battery wire and the ground wire must be same size. Fix the wires securely with the terminal screws. The above illustration shows the gain set to NORMAL. With high output the signal waveform is distorted, if you raise the gain of the amplifier the power changes only slightly. [. . . ] DO NOT allow amplifier to come into contact with liquids due to, for example, the location where the amplifier is installed. Also, amplifier and speaker damage, smoke, and overheating could result from contact with liquids. In addition, the amplifier surface and the surface of any attached speakers could become hot to the touch and minor burns could result. To ensure proper installation, use the supplied parts in the manner specified. [. . . ]
