I think the cheapest way is to get 4 cables(2 per side) and ensure that your connections at your amp can accomodate both terminations. Will there be enough room to place 2 spades at each terminal, say on top of each other? If not, then does your amp have 5 way binding posts? If so, then you can use spades and bananas, one cable having spades and the other having bananas. My bi-wires were terminated by the factory and had both wires joined into 1 pair of terminations for connection to the amp but they have 2 pairs at the speaker end. There are many posters here who believe that you should use a better than average single wire vs bi-wiring using an average cable. As it is system dependant, only you will know in the end. Good luck and report back on your findings.
