Notes
•This unit is for vehicles with a
•To avoid shorts in the electrical system, be sure to disconnect the ≠ battery cable before beginning installation.
•Refer to the owner’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, 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 short- circuiting 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 pro- tection 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 this unit.
•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 50 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 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
•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
Such connection could cause excessive cur- rent drain and malfunction.
