Connections/Installation Connections WARNING • When speaker output is used by 4 channels, use speakers over 50 W (maximum input power) and between 4 Ω to 8 Ω (impedance value). Do not use 1 Ω to 3 Ω speakers for this unit. • When rear speaker output is used by 2 Ω of subwoofer, use speakers over 70 W (maximum input power). * Please refer to connections for a connection method. • The black cable is ground. When installing this unit or power amp (sold separately), make sure to connect the ground wire first. Ensure that the ground wire is properly connected to metal parts of the car's body. The ground wire of the power amp and the one of this unit or any other device must be connected to the car separately with different screws. If the screw for the ground wire loosens or falls out, it could result in fire, generation of smoke or malfunction.

ACC position No ACC position • Use this unit with a 12-volt battery and negative grounding only. Failure to do so may result in a fire or malfunction. • To prevent a short-circuit, overheating or malfunction, be sure to follow the directions below. - Disconnect the negative terminal of the battery before installation. - Secure the wiring with cable clamps or adhesive tape. Wrap adhesive tape around wiring that comes into contact with metal parts to protect the wiring. - Place all cables away from moving parts, such as the shift lever and seat rails. - Place all cables away from hot places, such as near the heater outlet. - Do not connect the yellow cable to the battery by passing it through the hole to the engine compartment. - Cover any disconnected cable connectors with insulating tape. - Do not shorten any cables. - Never cut the insulation of the power cable of this unit in order to share the power with other devices. The current capacity of the cable is limited. - Use a fuse of the rating prescribed. - Never wire the negative speaker cable directly to ground. - Never band together negative cables of multiple speakers. • When this unit is on, control signals are sent through the blue/white cable. Connect this cable to the system remote 2 En control of an external power amp or the vehicle's auto-antenna relay control terminal (max. 300 mA 12 V DC). If the vehicle is equipped with a glass antenna, connect it to the antenna booster power supply terminal. • Never connect the blue/white cable to the power terminal of an external power amp. Also, never connect it to the power terminal of the auto antenna. Doing so may result in battery drain or a malfunction. • The graphical symbol placed on the product means direct current. This unit Perform these connections when using a subwoofer without the optional amplifier.
