Power Supply Connections
The +12VDC and GROUND wires should be heavy gauge copper wire with heavy
insulation and of the same gauge. Please see the chart below for recommended
gauge and fuse.
F300.4 60 AMP FUSE 8 GAUGE
F300.1 60 AMP FUSE 8 GAUGE
In addition, it has a 12V remote control wire and it should be 14AWG-18AWG.
It is preferable to have longer speaker wires and shorter power supply wires to
minimize power losses.
+12V Power (+12V)
This wire is usually connected directly to the positive battery terminal. Be sure to
use proper fuse as rated above within 16 inches of the main battery.
(Refer to Fig. 1)
Ground (GND)
Same gauge as +12V and no longer than 36”
This connection must be completed using an “O” ring (to prevent coming loose)
with insulating sleeve. This wire is the electrical ground and must be fastened
securely to the vehicle chassis. The best method is to use threading sheet metal
screw(s) since the threads cut into bare metal. Ensure that all paint coating or
other insulation is removed from around the ground area.
Use as short of a piece
of cable as possible
–
Again, use the same gauge as the +12V.
(Refer to Fig. 1)
Remote (REM)
Many source units (cd player) or other music sources have an output terminal for
connection of the remote turn-on of the power amplifier. If the source unit doesn’t
have a remote turn-on feature, then you can connect the remote wire to a switch
that derives power from an ignition switched circuit.
(Refer to Fig. 1)
Caution
First make +12V wire connection then the ground connection and finally the
remote connection. Furthermore the +12V wire must always be fused at the
battery for protection against possible damage. If you need to replace the power
fuse, replace it with a fuse of the same value. Using a fuse of a different type or
rating may result in a serious hazard.
