[. . . ] Use the supplied hexagonal wrench to tighten screws when fastening wires to the terminal. The use of a long, commercially available hexagonal wrench can cause excessive torque to be applied possibly resulting in damage to terminals and wires.

[. . . ] If you decrease the volume of the head unit and set the gain control of the amplifier to the proper position but still the sound cuts out from time to time, contact the nearest authorized PIONEER Service Station. Relationship between the gain of the amplifier and the output power of the head unit Power Normal gain Equal power Power Maximum gain If you raise the gain of the amplifier to an improper level, only distortion is increased and the power increases only slightly. With high output the signal waveform is distorted, if you raise the gain of the amplifier the power changes only slightly. The above illustration shows the gain set to NORMAL. 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. Do not connect a cord having an exposed core wire to the power terminals of this amplifier (Power terminal, GND terminal, System remote control terminal). Since the wire will become loose over time, it must be periodically inspected and tightened as necessary. Do not solder or bind the ends of the twisted wires. Fasten while making sure to not to clamp the insulating sheath of the wire. Use the supplied hexagonal wrench to tighten and loosen the terminal screw of the amplifier. securely fasten the wire with the terminal screw. 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. 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. 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. [. . . ] 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. [. . . ]
