Mounting and wiring this product requires skills and
experience. For safety's sake, leave the mounting and
wiring work to professionals.
Make sure to ground the unit to a negative 12V DC
Do not install the unit in a spot exposed to direct
sunlight or excessive heat or humidity. Also avoid
places with too much dust or the possibility of water
If the power is not turned ON ("PROTECT" is
displayed), the speaker wire may have a short-
circuit or touched the chassis of the vehicle and
the protection function may have been activated.
Therefore, the speaker wire should be checked.
If your car's ignition key switch does not have an
ACC position, connect the ignition wires to a power
source that can be turned on and off with the
ignition key. If you connect the ignition wires to
a constant-voltage power source, as with battery
wires, the battery may die.
If the console has a lid, make sure to install the unit
so that the faceplate will not hit the lid when it is

Insulate unconnected wires with vinyl tape or other
similar materials. To prevent a short circuit, do not
remove the caps on the ends of the unconnected
wires and terminals.
Connect the speaker wires correctly to the
corresponding terminals. The unit may be damaged
or fail to work if you share the - wires or ground
them to any metal part in the car.
When connecting only two speakers, connect
the connectors either to both of the front output
terminals or to both of the rear output terminals
(do not mix front and rear terminals). For example,
if you connect the + connector of the left speaker
to a front output terminal, do not connect the -
connector to a rear output terminal.
After the installing the unit, check whether the brake
lamps, blinkers, wipers, etc. on the car are working
Mount the unit so that the mounting angle is 30°
