Connecting the Power Terminal
• Always use the recommended battery and ground
wire, which is sold separately. Connect the battery
wire directly to the car battery positive terminal
(+) 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.
• Use a 10 AWG to 20 AWG wire for the system
remote control wire.

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. Expose the end of wires using nip-
pers or a cutter.
• Battery wire, ground wire:
23 mm to 25 mm (7/8 in. to 1 in.)
• System remote control wire:
14 mm to 16 mm (1/2 in. to 5/8 in.)
3. Connect the wires to the terminal.
• 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.
• Cut off any excess portions of the wire ties.
