WARNING

!Use speakers over 50 W (output value) and between 4 W to 8 W (impedance value). Do not use 1 W to 3 W speakers for this unit.

!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 con- nected 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 con- nected to the car separately with different screws. If the screw for the ground wire loos- ens or falls out, it could result in fire, genera- tion of smoke or malfunction.

!Use this unit with a 12-volt battery and nega- tive grounding only. Failure to do so may re- sult in a fire or malfunction.

!To prevent a short-circuit, overheating or mal- function, be sure to follow the directions below.

—Disconnect the negative terminal of the bat- tery before installation.

—Secure the wiring with cable clamps or adhe- sive 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 multi- ple speakers.

!When this unit is on, control signals are sent through the blue/white cable. Connect this cable to the system remote control of an ex- ternal power amp or the vehicle’s auto-anten- na 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.
