•To avoid shorts in the electrical system, be sure to disconnect the · battery cable before begin- ning installation.
•Refer to each product’s manual for details on connecting the power amp and other units, then make connections correctly.
•Secure the wiring with cable clamps or adhe- sive tape. To protect the wiring, wrap adhesive tape around them where they lie against metal parts.
•Route and secure all wiring so it cannot touch any moving parts, such as the gear shift, hand- brake and seat rails. Do not route wiring in places that get hot, such as near the heater out- let. If the insulation of the wiring melts or gets torn, there is a danger of the wiring short- circuiting to the vehicle body.
•Don’t pass the yellow lead through a hole into the engine compartment to connect to the bat- tery. This will damage the lead insulation and cause a very dangerous short.
•Do not shorten any leads. If you do, the protec- tion circuit may fail to work when it should.
•Never feed power to other equipment by cut- ting the insulation of the power supply lead of the unit and tapping into the lead. The current capacity of the lead will be exceeded, causing overheating.
•When replacing fuse, be sure to use only fuse of the rating prescribed on the fuse holder.
•Since a unique BPTL circuit is employed, never wire so the speaker leads are directly grounded or the left and right · speaker leads are common.
•Speakers connected to this unit must be high- power types with minimum rating of 45 W and impedance of 4 to 8 ohms. Connecting speak- ers with output and/or impedance values other than those noted here may result in the speak- ers catching fire, emitting smoke or becoming damaged.
•When this product’s source is switched ON, a control signal is output through the blue/white lead. Connect to an external power amp’s sys- tem remote control or the car’s
•When an external power amp is being used with this system, be sure not to connect the blue/white lead to the amp’s power terminal. Likewise, do not connect the blue/white lead to the power terminal of the

•If this unit is installed in a vehicle that does not have an ACC (accessory) position on the igni- tion switch, the red lead of the unit should be connected to a terminal coupled with ignition switch ON/OFF operations. If this is not done, the vehicle battery may be drained when you are away from the vehicle for several hours.
