[QUOTE="Jeremiah25, post: 2970367, member: 570469"] So let me ask you some questions. You are claiming to have set the gain with a DMM, but how exactly did you do that? Do you somehow magically know the output voltage where the amp starts to clip at every frequency without knowing the reactive impedance, and the exact power output capabilities of the amplifier at a reasonable percentage of distortion at each reactive impedance? I'm haveing a hard time figureing out how you could possibly set the gain properly with a DMM without knowing the said information, and I'm quite confident that you don't know the said information. If you do...................I need to borrow your crystal ball. I'm not trying to be an *** here, but you failed at setting the gains properly. Next time try using an oscilloscope instead of a DMM. The only reason you should use a DMM for setting the gains is to gain match multiple amplifiers, because a DMM does not tell you when the amp is clipping. It will simply tell you the highest possible voltage the amp will put out at whatever frequency you are playing and reactive impedance at that frequency, but it does not tell you how distorted or clipped that voltage is. If you are running the amp at the highest possible voltage that it can put out, you have reached full clipping on the amplifier. An oscilloscope is the only way to see the output wave form to ensure the output is not too distorted. [/QUOTE]
