Wiring two post speakers with biwire cable

Hello
You will want to connect the wires at the amp as they shold be. At the speaker end you NEED to connect all 4 wires as they should be + and + to + post and - and - to the - post (unless using phase reversing then keep togother ++ and --and reverse). If you do not you MUST TAPE off the lose wires as they connect as a single + and single - wire at the amp which means that if not connect at the speaker as well you have two hot wire floating around there that can short out. Also by connecting the 4 wires you are just increasing you wire size, which in almost all cases is a good thing. Good luck Bob

Craig (Garfish) is correct that bi-wiring makes little sense if your speakers have only one set of binding posts. The advantage of bi-wiring your speakers will NOT be realized unless the speaker has two internal crossovers to provide a separate signal to the mid/high frequency drivers, and another to the bass/low frequency driver. The two signals your amp will send to the speaker will simply be combined at the speaker's crossover. There is even a chance that you may degrade the sound, since using the set of bi-wires will simply increase the capacitance that the signal sees.

You guys need to read his question. He asked if he could use biwire cables on non biwire speakers. He does not intend to modify the speakers to biwire.

What you are proposing is called shotgunning and the results will tend toward a somewhat looser and fuller sound than a conventional single run of the same cables.It is normally used in tailoring a system to acquire a larger presentation.
You can alternately attach just a single set of connectors to the speaker end of the biwire pair for an interesting and educational experiment in capacitive loading.The sonic results will vary depending on your amplifier and the particular speakers being used.
As Aknorth stated, the unused ends should be securely taped over or fitted with wire caps to prevent an accidental short.

If your speaker cables are the same as the non-biwire versions you will not be shotgunning. Many brand of speaker wires are bi-wire capable. There are mulitple conductors (separate wires) per channel. All they do is segregate the separate conductors into 4 on the speaker end instead of 2. These type of cables will therefore be no different than the non biwire cables if used on your speakers.
