POWER CONNECTIONS
Before installing the amplifier, disconnect the
negative (ground) wire from the vehicle/vessel’s
battery. This will prevent accidental damage to
the system, vehicle/vessel and your body during
installation.
Ground Remote +24 VDC
NOT FOR USE IN 12V SYSTEMS!
The M600/6-24V’s “+24 VDC” and “Ground”
connections are designed to accept up to 4 AWG
power wire. 8 AWG is the required wire size for
this amplifier.
If you are installing the M600/6-24V with
other amplifiers and wish to use a single main
power wire, use 4 AWG, 2 AWG or 1/0 AWG
main power wire (depending on the overall
current demands of all the amplifiers in the
system). This 4, 2 or 1/0 AWG power wire should
terminate into a fused distribution block mounted
as close to the amplifiers as possible (within 12
inches / 30cm of wire length). The fused output
of the distribution block will connect to the
M600/6-24V with 8 AWG power wire. JL Audio
ECS fused distribution blocks are recommended
(XD-FDBU-2 and XD-FDBU-4)
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 wires to the amplifier,
first back out the set screw on the top of the
terminal block, using the supplied 2.5 mm hex
wrench. Strip 1/2 inch (12 mm) of insulation from
the end of each wire and insert the bare wire into
the terminal block, seating it firmly so that no
bare wire is exposed. While holding the wire in
place, tighten the set screw firmly, taking care not
to strip the head of the screw.
The ground connection should be made using
the same gauge wire as the power connection.
Any wires run through barriers must
be protected with a high quality rubber
grommet to prevent damage to the
insulation of the wire. Failure to do so
may result in a dangerous short circuit.
Many vehicles/vessels employ small (10 AWG -
6 AWG) wire to connect the alternator’s
positive connection to the battery and ground
connection to the chassis or battery. To prevent
voltage drops, these wires should be upgraded,
where possible, to 4 AWG when installing
amplifier systems with main fuse ratings above
60A.
FUSE/CIRCUIT BREAKER REQUIREMENTS
It is absolutely vital that the main power
wire(s) to the amplifier(s) in the system be
fused within 18 inches (45 cm) of the positive
battery post connection. The fuse value at each
power wire should be high enough for all of the
equipment being run from that power wire. If
only the M600/6-24V is being run from that
power wire, we recommend a 30A fuse or circuit
breaker be used.
If fusing the amplifier near its power
connections (when more than one amp is being
run from the main power wire), use a 30A fuse.
MAXI™ (big plastic-body) fuses or JL Audio
marine-grade circuit breakers are recommended.
