I do it by ear. The pitch of the test tone will get higher when the clipping kicks in. From there, dial it back 2-3db. You can probably search for some clipped test tones to get idea of what they sound like and how sensitive to clipping your ears are.

You can also watch the sub movement with tones...once the movement changes its clipping

Here you go. All you need is a speaker and a tweeter capacitor.

Don't know if anybody else noticed, but like Spokey said the clipping is visual too.

Now I want to get an oscilloscope just to test my ear!

I have one of the cheap O scopes. You will think of things to do with it once you get one. it is a good tool for high powered car audio. Like I know for a fact that my headunit rca’s don’t clip at full volume. At any frequency.
