[. . . ] · When more than one power amplifier are going to be used, use a power supply wiring wire and protective fuse of greater current-handling capacity than the total maximum current drawn by each amplifier. Example: One Power Amplifier Is Used Installation procedure 1. Remove the ignition key and disconnect the negative - terminal of the battery to prevent short circuits. Set the unit according to the intended usage. Connect the input and output cables of the units. Connect the power wire, power control wire and grounding wire following this order. Connect the negative - terminal of the battery. 2WARNING s Accessories Part name Terminal cover (Power terminal) Self-tapping screws (ø4 ´ 16 mm) Speaker level input cable External View Number of Items 1 4 1 To prevent injury or fire, take the following precautions: · When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with a 3mm2 (AWG12) or more to prevent wire deterioration and damage to the wire coating. · To prevent a short circuit, never put or leave any metallic objects (such as coins or metal tools) inside the unit. · If the unit starts to emit smoke or strange smells, turn off the power immediately and consult your Kenwood dealer. · Do not touch the unit during use because the surface of the unit becomes hot and may cause burns if touched. 2CAUTION Installation Since the power amplifier has no parts which require operation, it can be installed at a position away from the driver's seat without any hindrances. As generally accepted positions for its installation, places such as inside the trunk, etc. Changes or modifications to this equipment may cause harmful interference unless the modifications are expressly approved in the instruction manual. The user could lose the authority to operate this equipment if an unauthorized change or modification is made. · Do not install the unit under the carpet. Otherwise heat build-up occurs and the unit may be damaged. · Install this unit in a location which allows heat to easily dissipate. Once installed, do not place any object on top of the unit. · The surface temperature of the amplifier will become hot during use. Install the amplifier in a place where people, resins, and other substances that are sensitive to heat will not come into contact with it. · When making a hole under a seat, inside the trunk, or somewhere else in the vehicle, check that there is nothing hazardous on the opposite side such as a gasoline tank, brake pipe, or wiring harness, and be careful not to cause scratches or other damage. · Do not install near the dashboard, rear tray, or air bag safety parts. · The installation to the vehicle should securely fasten the unit to a place in which it will not obstruct driving. If the unit comes off due to a shock and hits a person or safety part, it may cause injury or an accident. [. . . ] Use the diagram on the right as a guide.
