PRECAUTIONS : READ FIRST!
ME-400D OWNER’S MANUAL 
4 CHANNEL CLASS D POWER AMP 
•   
•  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 heat sink 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 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 the proper power and ground 
wire 10 gauge minimum.
