Speaker output terminals
• Stereo Connections:
When you wish to use the unit as a stereo
amplifier, stereo connections are used.
The speakers to be connected should
have an impedance of 2
Ω
or greater.
When multiple speakers are to be
connected, ensure that the combined
impedance is 2
Ω
or greater for each
channel.
• Bridged Connections:
When you wish to use the unit as a high-
output monaural amplifier, bridged
connections are used. (Make connections
to the LEFT channel
9
and the RIGHT
channel
·
SPEAKER OUTPUT terminals.)
The speakers to be connected should
have an impedance of 4
Ω
or greater.
When multiple speakers are to be
connected, ensure that the combined
impedance is 4
Ω
or greater.
The rated input of the speakers should be
no less than the maximum output of the
amplifier. Otherwise malfunction may
result.

• The genuine-accessory car stereo shall
have a maximum power output of no
more than 40 W.
• Do not connect the speaker output leads
from a power amplifier (Optional) to the
speaker level input terminals of this unit,
for this may cause malfunction or
damage.
• Do not connect cables and leads to both
RCA cable input jacks and the speaker
level input terminals simultaneously, for
this may cause malfunction or damage.
• Connect the power control lead to a
power supply which can be turned
ON/OFF by the ignition key switch (ACC
