how to set up a jamo 250 sub with an amp

i'm stumped. i have a jolida int. amp with only output speaker terminals and want to set up a sub with speaker level inputs terminals only. the manual has the speaker wires from the amp going to the level inputs on the sub.excuse my ignorance but how do i get power to the speakers?
Wire your speakers from the amp and add another set of speaker wire from amp outputs to the speaker level inputs on the sub.
2 pairs of speaker wire.
