Notes on electrical connections:
•
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 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
“Amplifier Gain” setting to prevent the speakers from
being damaged (see page 49 of the INSTRUCTIONS).
• To prevent short circuits, 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.
