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 only 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 40 watts at
the rear and 40 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.
