That's the peak output - probably with the head unit run off an
unrealistically high power supply voltage.

Anything exceeding the rated output of the head unit.

They're perfectly capable of handling the head unit power, but not
amazingly good speakers. Wattage figures are 99% hype, and almost
completely irrelevant. All they tell you is the thermal power
limitations of the speaker before the voice coil fails. The only thing
that can tell you whether a speaker is actually any good is your own
ears. If you want an honest opinion though, you'd do well to spent
another £20-30, and to look towards US or European manufactured
speakers, which generally sound better than similarly priced Japanese
equivalents.
