!
When installing this unit, make sure to con-
nect the ground wire first. Ensure that the
ground wire is properly connected to metal
parts of the car

s body. The ground wire of the
one of this unit must be connected to the car
separately with different screws. If the screw
for the ground wire loosens or falls out, it
could result in fire, generation of smoke or

with liquids. Electrical shock could result.
Also, damage to this unit, smoke, and over-
heating could result from contact with liquids.
The surfaces of the amplifier and any attached
speakers may also heat up and cause minor
burns.
!
In the event of any abnormality, the power
supply to the amplifier is cut off to prevent
equipment malfunction. If this occurs, switch
the system power off and check the power
supply and speaker connections. If you are un-
able to determine the cause, please contact
