You can connect the crossover's low frequency outputs to the ampli- Þer's rear channel inputs, and the crossover's higher frequency outputs to the ampliÞer's front channel inputs.

This is an efÞcient system because the channels only amplify signals with- in the frequency range of the speaker element they are driving. Little power is wasted.
