Installation Installation Connecting the Units Note: • This unit is for vehicles with a 12-volt battery and negative grounding. Before installing it in a recreational vehicle, truck, or bus, check the battery voltage. • To avoid shorts in the electrical system, be sure to disconnect the · battery cable before beginning 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 adhesive 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, handbrake and seat rails. Do not route wiring in places that get hot, such as near the heater outlet. If the insulation of the wiring melts or gets torn, there is a danger of the wiring shortcircuiting to the vehicle body. • Don't pass the yellow lead through a hole into the engine compartment to connect to the battery. This will damage the lead insulation and cause a very dangerous short. • Do not shorten any leads. If you do, the protection circuit may fail to work when it should. • Never feed power to other equipment by cutting 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. • If the RCA pin jack on the unit will not be used, do not remove the caps attached to the end of the connector. • 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 highpower types with minimum rating of 45 W and impedance of 4 to 8 ohms. Connecting speakers with output and/or impedance values other than those noted here may result in the speakers 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 system remote control or the car's Auto-antenna relay control terminal (max. 300 mA 12 V DC). If the car features a glass antenna, connect to the antenna booster power supply terminal. • 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 auto-antenna. Such connection could cause excessive current drain and malfunction. • To avoid short-circuiting, cover the disconnected lead with insulating tape. Especially, insulate the unused speaker leads without fail. There is a possibility of short-circuiting if the leads are not insulated. • To prevent incorrect connection, the input side of the IP-BUS or optical cable connector is blue, and the output side is black. Connect the connectors of the same colors correctly. 139

tery. This will damage the lead insulation and
