[QUOTE="thch, post: 4625104, member: 562032"] thus far, from the thread, the "clipping" claim needs to be explained. Given the general difficulty for an objective measurement of clipping, and the general acceptance of mild clipping, it seems likely the term is being applied wrong. the following are problems and solutions: 1.) the amplifier is occasionally entering protect mode. a reduction in gains, or correction of wiring errors can fix this, with the latter being preferred. 2.) an inprecise tool, such as a DMM, is being misapplied to infer the form of distortion caused when the amplifier cannot force the speaker any further inward or outward due to its design limitations. this limitation is called "clipping". 3.) audible distortion is present. this may be an issue with any element in the audio system including the human and the speaker and the amp and the HU, and ect... A speaker bottoming out will certainly sound unplesant regardless of how clean the amplifier is. 4.) a precision instrument is used to determine clipping. Because the amplifier is set using a sine wave, and music is comprised of many sounds, some of which are delayed and reduced by filters, it may be possible that the summation of these filtered sounds will exceed the peak capabilities of the amplifier (even though the average power may be reduced). in general, #2 may be a non issue. #3 may mean you need a highpass/subsonic filter to prevent overexcursion. #4 is generally not solvable except by purchasing a larger amplifier, but it is also not terribly important either.
