What are some reasons to connect capacitors in series?

Well, maybe people rarely see this configuration; however, this trick could be used to create high-voltage bipolar capacitors. If you series-connect two equal value capacitors in series, cathode-to-cathode and use only the positive lead of each cap to connect to other part of the circuits. This trick are very often seen in audio equipments.
