[QUOTE="retrojordans, post: 7292185, member: 630134"] Horrible advice for a beginner. The gain should be set in accordance with the head unit or line driver's output voltage. An amp's wattage output directly coincides with the headunit's volume knob. If your head unit clips @ "volume 30" adjust your amp's gains so the amp puts out it's max unclipped power @ "volume 25". Now say your amp is putting out 1200 watts @ "volume 25"...At any volume under "volume 25" your amp will be putting out less than 1200 watts. So if your sub can "thermally" handle 1,000 watts for prolonged periods of time...Keep the volume slightly below "volume 25" because we know "volume 25" = 1200 watts. Would a 5000 watt amp blow the sub on "volume 1" ? No because a 5000 watt amp (properly adjusted) on "volume 1" may only be putting out 50 watts.. This point is moot to any beginner because to properly adjust an amplifier you need to use an oscilloscope on a tone source not music..Blah blah blah..Have a professional do it you will screw it up [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] no offense. Any amp's output is totally under the operators control via the source's (headunit) volume knob. The underlying point here is: when in doubt set any ego you may have aside and have a professional installer set everything up, and instruct you. [/QUOTE]
