    So... the ohms part of your question is answered in the ohms FAQ, which you should read through.

    The purpose of an external speaker jack is to add an additional speaker cab so that the amp's sound is coming from both the built-in speaker and the external cab. The reason it has an ohm rating is because all cabs must have a specific ohm-rating relationship to each other, and to the amp, in order to work well and not burn up the amp.

    That relationship is described in the FAQ. :)
