[. . . ] or the equivalent of an additional 10W per speaker. the amplifiers will increase their outpul power by approximately 50%. The current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2 Ohm load. If you lack adequate current, your music reproduction will be distorted .

Fuses Power fuses protect both the amplifier and the electrical system of your car from fault conditions. [. . . ] If the amplifier has shut down due to thermal overload. you should first allow it to cool down before restarting. If the shut down was due to either an input overload or a short circuit, be sure to correct these conditions before attempting to power up the amplifier again. SHOCK HAZARD!There are dangerous voltages present within the unit. There are no user-serviceable parts within the unit. MarIne MOSFET Amplifier User's Manual - page 5 Martnc MOSFET Ampllftor User's Manual· page 4 Mounting the amplifier 1. Find a suitable location in the marine vessel in which to mount the amplifier. Connecting the amplifier Before dOing <my wiring, look through this marual and identify the diagrams to follow for power. input and speaker connections for your particular installation. Be sure you understand all the connections before you proceed. 2. Make sure there is sufficient air circulation around the intended mounting location. 3. Mark the location for the mounting hole screws by positioning the amplifier where you wish to install it. Use a scribe or mounting screw, inserted through each of the amp's mounting holes, to mark the mounting surlace. Be sure to observe polarity to avoid audio phase problems, NOTE: Do not connect BOTH the high !evel and low level inputs from your receiver to your amplifier at the same time! 2-Channel Amplifier MR400. 2 , J NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same timet 2-Channel Amplifier MR400. 2 1"'"' -----" 7 To Audio Outputs of head unit or signal processor l+ l~ R· R. . .
