Installation precautions Before you drill or cut any holes, investigate your vessel's layout very carefully. Take special care when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring. Never operate the amplifier when it is unmounted. Attach all audio system components securely within the amplifier to prevent damage, especially in an accident. Do not mount this amplifier so that wire connections are unprotected, in a pinched condition, in contact with any metal surfaces in your marine vessel, or likely to be damaged by nearby objects. Before making or breaking power connections in your system, disconnect the marine vessel battery. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker terminals. If you need to replace the power fuse, replace it only with a fuse identical to that supplied with the amplifier. Using a fuse of a different type or rating may result in damage to your audio system or your amplifier which is not covered by the manufacturer's warranty. Fuses Power fuses protect both the amplifier and the electrical system of your boat from fault conditions. If you must replace a fuse in your Marine amp, use a fuse of exactly the same type and rating. Using a different type or rating of fuse may result in damage to your amp or marine vessel or cause a fire. Marine MOSFET Amplifier User's Manual - page 5
