POWER CONNECTIONS
Before installing the amplifier, disconnect the
negative (ground) wire from the vessel’s battery.
This will prevent accidental damage to the system,
the vessel and your body during installation.

power wire. 4 AWG is the required wire size for
this amplifier.
If you are installing the M600/1 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 AWG 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 M600/1

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 vessels employ small (10 AWG - 6 AWG)
wire to connect the alternator’s positive
connection to the battery. To prevent voltage
drops, this wire should be upgraded to 4 AWG
when installing amplifier systems with main
fuse ratings above 60A.

It is common for the alternator to be grounded
through its chassis. If the alternator is not
grounded through its chassis and instead employs
a small (10 AWG - 6 AWG) wire to connect to
ground, this wire should also be upgraded to 4
AWG when installing amplifier systems with main
fuse ratings above 60A.

FUSE 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 M600/1 is being run from that power
wire, we recommend a 50A fuse be used.

If fusing the amplifier near its power

to deliver outstanding fidelity and efficiency.
The M600/1 can be operated with a wide
variety of source units and system configurations.
Its frequency response is limited to the range
below 500 Hz. It is not designed for driving
midrange speakers or tweeters. Every aspect of its
operation has been optimized for low-frequency
amplification. For detailed specifications, please
