Connecting the Unit
Connecting the Power Terminal
• Always use the recommended battery and ground
wire, which is sold separately. Connect the bat-
tery wire directly to the car battery positive termi-
nal (+) and the ground wire to the car body.
• Recommended wires size (AWG: American Wire
Gauge) is as follows. The battery wire, the
ground wire and the optional direct ground wire
must be same size.
Battery Wire and Ground Wire Size
Wire Length less than 1.2 m 1.2—2.1 m 2.1—3.0 m
Wire Size 4 AWG 4 AWG 2 AWG
3.0—3.9 m 3.9—4.8 m 4.8—5.7 m 5.7—6.7 m
2 AWG 1 AWG 1 AWG 0 AWG
1. Pass the battery wire from the
engine compartment to the interior
of the vehicle.
• After making all other connections to the
amplifier, connect the battery wire terminal
of the amplifier to the positive (+) terminal of
the battery.
2. Twist the battery wire, ground wire
and system remote control wire.
3. Connect the wires to the terminal.
• Before connecting the wires to the terminals,
remove the endcap. After connecting the
wires to the terminals, attach the endcap.
• Fix the wires securely with the terminal
screws.
WARNING
Failure to securely fasten the battery wire to the ter-
minal using the terminal screws could cause the ter-
minal area to overheat and could result in damage
and injury including minor burns.
4. Put the wire ties in the slits and
wrap the wire ties around the wires.
• Wrap the wire tie around the wire insulation,
not the stripped wire.
