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
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 13 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.
Note :
When installing the unit on the mounting bracket,
make sure to use the 8 mm-long screws. If longer
screws are used, they could damage the unit.
