CAUTION
• Be sure to turn the power off before changing the setting of any switch.
• If the fuse blows, check wires for shorts, then replace the fuse with one of the same rating.
• Check that no unconnected wires or connectors are touching the car body. Do not remove caps
from unconnected wires or connectors to prevent short circuits.
• Connect the speaker wires to appropriate speaker connectors separately. Sharing the negative
wire of the speaker or grounding speaker wires to the metal body of the car can cause this unit
to fail.
• After installation, check that the brake lamps, winkers, and wipers work properly.

d a m a g e d .
• Install this unit in a location which allows heat to easily dissipate.
Once installed, do not place any object on top of the unit.
• The surface temperature of the amplifier will become hot during use. Install the amplifier in a
place where people, resins, and other substances that are sensitive to heat will not come into
contact with it.
• When making a hole under a seat, inside the trunk, or somewhere else in the vehicle, check
that there is nothing hazardous on the opposite side such as a gasoline tank, brake pipe, or
wiring harness, and be careful not to cause scratches or other damage.
• Do not install near the dashboard, rear tray, or air bag safety parts.
• The installation to the vehicle should securely fasten the unit to a place in which it will not
obstruct driving. If the unit comes off due to a shock and hits a person or safety part, it may
cause injury or an accident.
• After installing the unit, check to make sure that electrical equipment such as the brake lamps,
turn signal lamps and windshield wipers operate normally.
