[QUOTE="akheathen, post: 8787722, member: 629234"] are you measuring below 25hz, and is there a load connected? what ohm? what are you measurin the clipping? what percentage of clipping are you seeing? some amps run dirty power for their ratings, which can be more than 1% but start to show less than that below halfway to full power. run it higher and see if it starts making around 60v. it may be possible that its only making half bridge power, which should come in about 30v for the 2ohm 1800rms being 60v for full bridge. this could be an issue with one side of the outputs not working, or a bad rectifier diode not letting half the power supply through.... or just maybe you need to go through your grounds real good and then the powers, which sound pretty robust, overkill, actually. meter the power at the amp terminals when running hard, like full tilt, if you can. remember, power comes from the ground, but it can only flow as much as the weakest connection on either side. it doesnt exit the loop.
