ELECTRICAL CONNECTIONS WOzUÐdNJ

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.
