Ω to 8 Ω (impedance value). Do not use
1 Ω to 3 Ω speakers for this unit.
– When rear speaker output is used by 2
Ω of subwoofer, use speakers over 70 W
(maximum input power).
* Please refer to connections for a
connection method.

• When this unit is on, control signals are
sent through the blue/white cable.
Connect this cable to the system remote
control of an external power amp or the
vehicle's auto-antenna relay control
terminal (max. 300 mA 12 V DC). If the
vehicle is equipped with a glass antenna,
connect it to the antenna booster power
supply terminal.
• Never connect the blue/white cable to
the power terminal of an external power
amp. Also, never connect it to the power
terminal of the auto antenna. Doing so
may result in battery drain or a
malfunction.
• The black cable is ground. Ground cables
for this unit and other equipment
(especially, high-current products such as
power amps) must be wired separately. If
they are not, an accidental detachment
may result in a fire or malfunction.
• The graphical symbol
placed on
the product means direct current.
