Using two sets of speaker cable between
your amplifier and the crossover doubles
the signal carrying conductors from the
amplifier to the speaker, thus direct
coupling the high-pass and low-pass
portions of the crossover network to the
amplifier. This will minimize interaction
between the two sections of the cross-
over network.
