ELECTRICAL CONNECTIONS
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 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 IN-CAR ENTERTAINMENT dealers.
• Replace the fuse with one of the specified rating. If the fuse blows frequently, consult your JVC IN-CAR
ENTERTAINMENT 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 IN-CAR ENTERTAINMENT dealer.
• Maximum input of the speakers should be more than 45 W at the rear and 45 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.
