• 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.
General setup (except [CLOCK]), Sound
setup, Display setup, BLUETOOTH setup,
radio presets, SiriusXM presets, and last-
connected device are automatically stored in
the internal memory of the unit:
– 10 seconds after the ignition is turned off
from the ACC position.
– 10 seconds after the unit is turned off by
pressing and holding OFF.
• Before connecting the speakers, turn the
unit off.
• Use speakers with a 2 impedance or 4
to 8 impedance, and with adequate
power handling capacities to avoid
damage.
Subwoofer direct 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 impedance or 4 to 8
impedance, and with adequate power handling
capacities to avoid damage.
Speaker connection for high
volume playback
For high volume playback, you can connect
front speaker in parallel.
For this connection:
– Set [SPEAKER LOAD] in [GENERAL] to
[2 OHM].
– Connect the subwoofers to right and left
rear speaker leads or use a dual voice coil
subwoofer with 4 to 8 impedance.
Notes
• When using a subwoofer with dual voice coil, or
using subwoofer(s) by connecting to 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).
