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

>What wattage speakers would be applicable to this head unit?


Anything exceeding the rated output of the head unit.

>So are these speakers good enough for my 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.
