Parts list for installation and connection
The following parts are provided for this unit. If any item is missing, consult your JVC car audio dealer
immediately.
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 Ωto 8 Ω). If the maximum power is less than
50 W, change “AMP GAIN” setting to prevent the speakers from being damaged (see page 12 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.
