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 car audio
dealers.
• It is recommended to connect to the speakers with maximum power of more than 50 (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 , change “AMP GAIN” setting to prevent the speakers from being damaged (see page 14 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 unit.
PRECAUTIONS on power supply and speaker connections:
• DO NOT connect the speaker leads of the power cord to the car battery; otherwise, the unit
will be seriously damaged.
• BEFORE connecting the speaker leads of the power cord to the speakers, check the speaker wiring in
your car.
