Before you start
! Always install the amplifier on a flat surface.
Do not install the amplifier on a surface that
is not flat or on a surface with a protrusion.
Doing so could result in malfunction.
! When installing the amplifier, do not allow
parts such as extra screws to get caught be-
tween the amplifier and the automobile.
Doing so could cause malfunction.
! Do not allow this unit to come into contact
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
your dealer.
! Always disconnect the negative * terminal of
the battery beforehand to avoid the risk of
electric shock or short circuit during installa-
tion.
! Do not attempt to disassemble or modify this
unit. Doing so may result in fire, electric
shock or other malfunction.
CAUTION
! Always keep the volume low enough to hear
outside sounds.
! Extended use of the car stereo while the en-
gine is at rest or idling may exhaust the bat-
tery.
! Connect either of three subwoofers to the am-
plifier; 1: a subwoofer with a 300 W (GM-
D8601) / 500 W (GM-D9601) or larger nominal
input and an impedance 4 W, 2: a subwoofer
with a 500 W (GM-D8601) / 800 W (GM-D9601)
or larger nominal input and an impedance 2 W
or 3: a subwoofer with a 800 W (GM-D8601) /
1 200 W (GM-D9601) or larger nominal input
and an impedance 1 W.
If the nominal input and impedance are out of
the above ranges, the subwoofer may catch
fire, emit smoke or become damaged.
