ELECTRICAL CONNECTIONS

To prevent short circuits, we recommend that you disconnect the battery's negative terminal and
make all electrical connections before installing the receiver.
• Be sure to ground this receiver to the car's chassis again after installation.
Notes:
• Replace the fuse with one of the specified rating. If the fuse blows frequently, consult your JVC
IN-CAR ENTERTAINMENT dealer.
• It is recommended to connect to the speakers with maximum power of more than 50 W (both
at the rear and at the front, with an impedance of 4 Ω to 8 Ω). If the maximum power is less
than 50 W, change "AMP GAIN" setting to prevent the speakers from being damaged (see
page 21 of the INSTRUCTIONS).
• To prevent short-circuit, cover the terminals of the UNUSED leads with insulating tape.
• The heat sink becomes very hot after use. Be careful not to touch it when removing this
receiver.
