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 volts 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 below.) 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 45 watts at the
rear and 45 watts at the front, with an impedance of 4 to 8 ohms.
• 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.
