amPliFier mounting oPtions
The MHD600/4-24V has two mounting
options to ease in installation.
standard mounting
The standard method of mounting requires
removal of the four corner caps with the 3/16-
inch hex wrench included with your amplifier.
Using appropriate mounting screws (not
included), secure the amplifier in all four corners
and replace the corner caps.
lateral mounting Feet
Lateral Mounting Feet are also included
with your MHD600/4-24V to provide an
alternative mounting option. Each mounting
foot should be attached to the bottom of the
amplifier by screwing the provided bolt into
the bottom of the amplifier and up into the
corner cap with the supplied 1/8-inch hex
wrench. Next, using appropriate mounting
screws (not included), secure the amplifier
by its four Lateral Mounting Feet.
Check before drilling any holes in your vessel to
make sure that you will not be drilling through
a gas tank, brake line, wiring harness or other
vital vessel system.
control Panel securitY coVer
The MHD600/4-24V features a Control Panel
Security Cover. When installed, the cover ensures
that your amplifier settings are not accidentally
changed while creating a clean aesthetic for the
amplifier and your installation. The control panel
security cover is pre-installed at the factory and
must be temporarily removed for access to the
controls described throughout this manual.
The security cover is secured by a single 2.5
mm hex-head screw at the far right of the panel.
Loosen the hex-head screw to release the security
cover (it is not necessary to completely remove the
screw). To re-install the security cover once all
adjustments have been made, insert the tongue on
the cover’s left edge into the groove where the left-
side heatsink meets the control panel, hinge the
panel closed and secure the screw using the
supplied 2.5 mm hex wrench. Do not overtighten
the screw.
