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.
Power and Speaker Wiring If you need to replace the power fuse, replace it only with a fuse idenetical 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. Don't misuse the level control! Do not mistake the input level control for a volume control! It is designed ONLY to match the output level of your audio source to the input level of your amplifier.
The switches and gain settings are located behind a watertight plug, which also lights up when the amplifier is on. Be sure to replace the plug when finished with adjustments. 1. The INPUT LEVEL switch selects the input sensitivity of the amplifier. If you are connecting to a LINE level source (typically any RCA type connection) then the switch should be in the LINE (out) position. When connecting to loudspeaker outputs or headphone or high level sources then set the switch to the SPEAKER (in) position. 2.
