To prevent short circuits, we recommend that you disconnect the battery’s negative terminal and make all electrical connections before installing the unit. If you are not sure how to install this unit correctly, have it installed by a qualified technician.
Note:
This unit is designed to operate only on 12 V DC, NEGATIVE ground electrical systems. If your vehicle does not have this system, a voltage inverter is required, which can be purchased at JVC car audio dealers.
•Replace the fuse with one of the specified rating. If the fuse blows frequently, consult your JVC car audio dealer.
•If noise is a problem...
This unit incorporates a noise filter in the power circuit. However, with some vehicles, clicking or other unwanted noise may occur. If this happens, connect the unit’s rear ground terminal (see connection diagram) to the car’s chassis using shorter and thicker cords, such as copper braiding or gauge wire. If noise still persists, consult your JVC car audio dealer.
•Maximum input of the speakers should be
more than 50 W at the rear and 50 W at the front, with an impedance of 4 Ω to 8 Ω.
•Be sure to ground this unit to the car’s chassis.
•The heat sink becomes very hot after use. Be careful not to touch it when removing this unit.

PRECAUTIONS on power supply and speaker connections:
•DO NOT connect the speaker leads of the power cord to the car battery; otherwise, the unit will be seriously damaged.
•Connect the black lead (ground), yellow lead (to car battery, constant 12 V), and red lead (to an accessory terminal) correctly.
•BEFORE connecting the speaker leads of the power cord to the speakers, check the speaker wiring in your car.
–If the speaker wiring in your car is as illustrated in Fig. 1 and Fig. 2 below, DO NOT connect the unit using that original speaker wiring. If you do, the unit will be seriously damaged.
Redo the speaker wiring so that you can connect the unit to the speakers as illustrated in Fig. 3.
–If the speaker wiring in your car is as illustrated in Fig. 3, you can connect the unit using the original speaker wiring in your car.
–If you are not sure of the speaker wiring of your car, consult your car dealer.
