[QUOTE="The_Quiet_One, post: 8363638, member: 614562"] What are you talking about? Do you not know there is a difference between AC and DC voltage calculations? There is a phase angle you have to take into consideration when dealing with AC signal (Speaker output of the amp is AC) The DC version of Ohm's law and the DMM method gets you in the ballpark, but isn't a great way to set your gains imo. It's better than just guessing, but leaves a lot to be desired. HU volume to set gains depends on HU and telling OP to trust the 75% mark to be distortion free could lead to trouble depending on the head unit. Also depending on his electrical the voltage reading may be reflecting a square wave. Everything else you suggested I agree with though and he shouldn't run into issues unless he plays tones or plays heavily bass boosted music. It's important for OP to know some of the possible pitfalls of using the DMM method and roll with those considerations in mind. Op what's you head unit and electrical like? [/QUOTE]
