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.

NOT FOR USE IN 12V SYSTEMS!
The M800/8-24V’s “+24 VDC” and “Ground”
connections are designed to accept up to 4 AWG
power wire. 4 AWG is the required wire size for
this amplifier.
If you are installing the M800/8-24V with
other amplifiers and wish to use a single main
power wire, use 2 AWG or 1/0 AWG main power
wire (depending on the overall current demands
of all the amplifiers in the system). This 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 M800/8-
24V with 4 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 M800/8-24V is being run from that
power wire, we recommend a 40A 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 40A fuse.
MAXI™ (big plastic-body) fuses or JL Audio
marine-grade circuit breakers are recommended.
