you can do that with a voltmeter, set it to DC volts.
music is ac voltage- sine waves
distortion is a square wave- which the DC meter will see if it is generated within the headunit or amp.
a meter will not show distortion generated by a speaker reaching limits- but your ears will

I think he is talking about using the DC side of the DMM to identify distortion levels of the HU and amp.
I have the SMD DD1 so I'm not gonna burn my few brain cells on learning his technique but it would be a good topical read to see exactly how he does it and how it compares to a distortion meter.
