POWER CONNECTIONS
Before installing the amplifier, disconnect the
negative (ground) wire from the vehicle’s battery.
This will prevent accidental damage to the system,
the vehicle and your body during installation.
+12 VDC
Ground
Remo
The JX360/4’s “
+12VDC
” and “
Ground
”
connections are designed to accept 4 AWG power
wire.
4 AWG is a minimum power wire size for
this amplifier.
If you are installing the JX360/4 with other
amplifiers and wish to use a single main power
wire, use 2 AWG or larger main power wire
(depending on the overall current demands of all
the amplifiers in the system). This 2 AWG or
larger power wire should terminate into a fused
distribution block mounted as close to the
amplifiers as possible and should connect to the
JX360/4 with 4 AWG power wire.
Note:
Smaller AWG numbers mean bigger wire
and vice-versa (1/0 AWG is the largest, 2 AWG is
smaller, then 4 AWG, then 8 AWG, etc.).
To connect the power and ground wires
to the amplifier, strip 1/2-inch (12 mm) of
insulation from each wire and insert the bare
wire into the the appropriate terminal block
positions on the JX360/4. Use the supplied
2.5 mm hex wrench to secure the wire via
the screw on the top of each terminal.
The
“GROUND”
connection should be made
using 4 AWG wire and should be kept as short
as possible, while accessing a solid piece of sheet
metal in the vehicle. The surface of the sheet
metal should be sanded at the contact point
to create a clean, metal-to-metal connection
between the chassis and the termination of the
ground wire. The use of a #10 sheet metal screw
and star washer to lock down the connection is
advisable. Alternatively, you can use a specialized
grounding lug, such as the JL Audio XB-MGLU.
Any wires run through metal barriers (such as
firewalls), must be protected with a high quality
insulating grommet to prevent damage to the
insulation of the wire. Failure to do so may result
in a dangerous short circuit.

!
Many vehicles employ small (10 AWG -
6 AWG) wire to ground the battery to the
vehicle chassis and to connect the alternator’s
positive connection to the battery. To prevent
voltage drops, these wires should be upgraded
to 4 AWG when installing amplifier systems
with main fuse ratings above 60A.
FUSE REQUIREMENTS
An appropriate fuse at the main power wire(s)
to the amplifier(s) is vital for vehicle safety! This
fuse must be installed within 18 inches (45 cm)
of the positive battery post connection. If the
JX360/4 is the only device connected to this main
wire, use a 50A AGU or MAXI® fuse (no other
fuse is required in this situation).
When running multiple devices from one
main power wire, the main fuse value and rating
of the main power wire must be high enough
for all of the equipment being run from it. Use a
fused distribution block to split the main power
wire feed to each device, with appropriate fusing
and power wire for each device.
