ME-400 Installation Notes / Sketches
• The negative battery terminal must be disconnected before any electrical connections are
made.
• If after reading the directions you feel uncomfortable about installing the amplifier in your
vessel, or not equipped or competent to do so, you should have the amplifier installed by
an authorized installer
• Be sure to choose a location that provides substantial ventilation for the amplifier. The
location chosen should provide at least 2 inch of clearance above the amplifier for
adequate ventilation.
• If the amplifier is to be mounted vertically be sure that it is in a place where adequate air
will flow along the length of its heatsink fins for cooling.
• NEVER mount the amplifier up side down, this will cause the heat to rise back into the
amplifier causing thermal shutdown or possible permanent damage.
• Be sure to mount the amplifier to a strong, solid surface which will not give way under the
stress of a waves pounding the hull.
• Make sure that the mounting screws will not penetrate through the hull or into wiring or
control cables.
• NEVER ground the speaker leads and NEVER allow the speaker leads to come in contact
with each other. The speaker wire should be at least 16 gauge or lower.
• NEVER operate the amplifier without proper power and ground wire of at least 10 gauge or
lower.
• NEVER operate the amplifier without proper fusing. Fuse holder must be located with in 0.5
meters from the battery. This fuse is to protect the vessel, not the electronics. In case of a
short, the fuse will blow instead of the wire burning up. Using other than the recommended
fuse ratings at the battery and at the amplifier may cause damage to the amplifier and will
void your warranty.
• To help minimize interference, it is best to run the power cables along the side opposite of
the audio (RCA) cables.
• Whenever wires pass through metal, rubber or plastic grommets must be used to prevent
the metal from wearing through the installation and causing a short.
• Whenever possible, use cable ties, mounting clamps and similar wiring aids. Adding stress
relief loop to wiring is also advisable to prevent straining or breakage.
• The amplifier operates with any vehicle using a 12 volt negative ground system
• Remote turn on wire must be switched by the radio. If the radio does not have a remote
turn on or antenna output, connect to wire that has a positive 12 volt output when the key
is turned to the accessory position. If the amplifier does not turn off the battery will die.
• Do not listen to high volumes for extended periods of time or hearing damage may occur.
• This amplifier produces heat during normal operation and therefore can not be fully sealed
to prevent water ingress. Though designed to operate in the marine environment the unit
cannot be exposed to direct liquid contact. Such contact will void the product warranty.
