Good grades ofcrossover caps are designed to handle lots of current.
I have seen decent grades of metallized mylar caps get melted down due to heat from current flow, because they could not handle the current long term.
Met. PP caps of a good quality should be OK for power supply use, they ARE exposed to the ripple current of the PS, and since they are smaller than the electrolytics, they will be exposed to the entire ripple current, and as such must be able to handle it. SHould not be a problem, but I would not use anything less than quality PP in this position anyway.

Like I said, I'm using the extraneous XO caps hanging around from tweaking old DIY speaker projects.

      It would be a rare case of a crossover grade PP that did not have sufficinet voltage rating to handle a SS power supply.
      The surest thing is to look on the caps, they almost all have a rated voltage, adn the ones in the PS will have a rated voltage as well. If the xover caps meet ore xceed the rated voltage, no problem.
