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 “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.
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 car audio dealers.
