• During full-power operation, a current of more
than 15 A will run through the system. Therefore,
make sure that the wires to be connected to the
+12 V and GND terminals of this unit are at least
14-Gauge (AWG14) or have a sectional area of
more than 2 mm² (
3
/
32
in).
When making the speaker parallel connection, use
wires with more than 12-Gauge (AWG12) or wires
that have a sectional area of more than 3.5 mm²
(
5 /
32
in).
If you have any questions or problems
concerning the connection, consult the
dealer for details.
Memory hold connection
When the yellow power supply lead is
connected, power will always be supplied to
the memory circuit even when the ignition
switch is turned off.
Speaker connection
• Before connecting the speakers, turn the
unit off.
• Use speakers with a 2 Ω impedance or 4 Ω
to 8 Ω impedance, and with adequate
power handling capacities to avoid
damage.
Subwoofer Easy Connection
You can use a subwoofer without a power
amplifier when it is connected to a rear
speaker lead.
To enable the connection, set [SUBW MODE]
in [SUBW DIRECT] to [1] to [3].
Note
Use a subwoofer with a 2 Ω impedance or 4 Ω to 8
Ω impedance, and with adequate power handling
capacities to avoid damage.
Speaker Parallel Connection
When making the speaker parallel
connection for a high volume playback, be
sure to:
– Set [SPEAKER LOAD] in [GENERAL] to
[2 OHM].
Notes
• When using a subwoofer with dual voice coil, or
using a subwoofer by connecting the right and left
rear speaker leads, be sure to set [SPEAKER LOAD]
in [GENERAL] to [2 OHM].
• To exert the speaker’s potential, make the power
connection to the battery directly (page 17).
