[. . . ] 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. General precautions Before installing and using your new amplifier, please become familiar with all the information contained in this manual. Please keep this manual in a safe place for future reference. [. . . ] -or· Run a #0 cable from the fuse holder at the battery to a distribution block at or near the amplifier's location. Then run separate cables from the amplifier to this distribution block and to independent chassis ground points. Connect all line inputs and outputs (if used) using high-quality cables. Connect all speakers, following the diagrams in this manual. Be sure to observe proper polarity to avoid audio phase problems. Insert fuse(s) into the battery fuse holder(s). Recheck all connections before powering up the amplifier. Set all level controls to minimum position, and set all crossover controls/switches to the desired frequency points. Power up the head unit and the amplifier. Then set the volume control on the head unit to about 3/4 volume, and adjust the amplifier's input level control(s) to just below the level of distortion. Further fine tuning of the various controls may be necessary to obtain best results. Connecting the amplifier Before doing any wiring, look through this manual and identify the diagrams to follow for power, input and speaker connections for your particular installation. There are dangerous voltages present within the unit. There are no user-serviceable parts within the unit.

If problems persist, read the following troubleshooting tips which may help eliminate the problems. POSSIBLE REMEDY Check to make sure you have a good ground connection. Check that the Remote Input (Turn-On) has at least 3VDC. Check that there is battery power on the (+) terminal. Make sure that the Protection LED is not illuminated. [. . . ] Try to set the head unit as high as possible (without distortion) and the amp input level as low as possible. Check for improperly grounded RCA interconnects. Check that the Input Level Control is set to match the signal level of the head unit. Always try to set the Input Level as low as possible. [. . . ]
