PRECAUTIONS on power supply
and speaker connections:

• DO NOT connect the speaker leads of the

power cord to the car battery; otherwise, the
unit will be seriously damaged.

• Connect the black lead (ground), yellow lead (to

car battery, constant 12 V), and red lead (to an
accessory terminal) correctly.

• BEFORE connecting the speaker leads of the

power cord to the speakers, check the speaker
wiring in your car.
– If the speaker wiring in your car is as

illustrated in Fig. 1 and Fig. 2 below, DO NOT
connect the unit using that original speaker
wiring. If you do, the unit will be seriously
damaged.
Redo the speaker wiring so that you can
connect the unit to the speakers as illustrated in
Fig. 3.

– If the speaker wiring in your car is as

illustrated in Fig. 3, you can connect the unit
using the original speaker wiring in your car.

– If you are not sure of the speaker wiring of your

car, consult your car dealer.
