INSTALLATION / CONNECTION
PREPARATION
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.
WARNINGS
To prevent short circuits, we recommend that you disconnect the battery’s negative terminal and make all electrical
connections before installing the unit.
• Be sure to ground this unit 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 45 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 45 W, change “AMP GAIN” setting to prevent the
speakers from being damaged (see “General settings—PSM”).
• 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
unit.
