ELECTRICAL CONNECTIONS

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 24 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.
