[. . . ] Prepare the power cable for attachment to the amplifier by stripping 1/2" of insulation from the end of the wire. Trim the power cable within 18" of the battery and strip1/2"of insulation from the end of the wire. Strip 1/2" from the battery end of the power cable and crimp a large ring terminal to the cable. NOTE: ALWAYS protect the battery and electrical system from damage with proper fusing. [. . . ] If noise is still present, contact your local authorized dealer or Lightning Audio customer service. When using a Master/Slave setup do not exceed more than two amplifiers. Strip the speaker wires 1/2" and insert into the speaker terminal and tighten the setscrew to secure into place. Be sure to maintain proper speaker polarity. DO NOT chassis ground any of the speaker leads as unstable operation may result. Check all power and ground connections for frayed wires and loose connections. Complete the installation by installing the proper value fuse. Operation Adjusting Level: To adjust the level setting, turn the amplifier gain level to the lowest setting. Turn the source unit volume up until distortion is audible and then slowly down until the distortion is inaudible (approximately ¾ volume position). Next, increase the amplifier level setting until once again distortion is audible and then down slowly until the distortion is inaudible. NOTE: Proper level setting is done by a trained professional utilizing an oscilloscope. for a more in depth setting procedure , contact Lightning Audio Technical Support. In a Master/Slave setup ONLY adjustments made to the master amplifier will effect the output. With the system playing at normal listening level, turn the crossover adjustment knob up slowly until the desired crossover point is achieved. Example: subwoofers- low pass with an 80Hz crossover point and full-range- high pass with a 100Hz crossover point NOTE: Some models include a subsonic filter with a variable 15-40Hz high pass filter designed to prevent frequencies below the audio range from being applied to the subwoofer from the amplifier. Set this to your personal preference while listening to the system. In a Master/Slave setup ONLY adjustments made to the master amplifier will effect the output. Amplifier does not turn on B+ or REM not between 10.
