You can run 2 pairs of speaker cables from the binding post on the amp to both the sub's speaker level inputs and to the speakers. If your amp has different taps to account for the change in effective speaker impedance you may want to try the different taps.
Since you are going to need to buy/build an additional set of speaker cables anyway, try it both ways. Try connected through the sub and out to the speakers and try connecting both directly to the amp. Whichever you prefer is the correct answer.
