Do I Biwire, or run sub cable and use just one out from biwire cable?

Ok, strange question here.

I currently have front speakers (Boston acoustics VR3) with biwire cable running from them (+ and - from receiver splits to hi + and - and low + and - at the speaker). I am replacing the speakers with polk Audio lsi25's (just purchased) which are biwire capable, but also capable of running speaker wire to the highs's and a sub wire to the lows (the speakers have a powered sub).

Now, I obviously have the biwire speaker cable, but I also have a spare sub interconnect lying around. I was told (polk user guide) that running speaker cable to the top set of binding posts (removing the jumpers) and running the sub cable from the front preouts to the subwoofer in would produce the best sound.

However, I only have a biwire speaker cable, so can I do that (would I have to do anything to the two ends of the biwire cable not being used, besides make sure they don't touch anything else? I mean would two unused ends hanging in space degrade the sound at all)?

Or should I just connect the biwire to the hi and low binding posts and forget the sub cable until i buy a new single wire cable.

Thanks.
I'm read the manual, and the hookup options.
I'm just wondering if just using one set of + and - ends from the quad end of the biwire cable is something that can be done. Would the other + and - ends hanging in space produce any negative effects on the sound?

Oh, I see what you're asking.
Since the wire is already bought and paid for, go ahead and use both hookups.
If for some reason you can't or don't want to hook up both; you can use electrical tape on the ends of one set.
At this point; why not use them, since you've got them.

Cool. I was thinking electrical tape, I just wanted to make sure.
The reason why I don't want to use both hookups is because I have a sub cable laying around which I can use as the hook up for the sub on the tower. Doing so means I can only use one set of the biwire to the top binding posts. (IE: I can't hook into BOTH binding posts and the sub. I either hook into both binding posts or the top binding post and the sub.) Hence using just one set of the biwire since I don't have a single wire cable laying around.

I know, it's a pretty unique scenario. Who the heck has biwire cable to use but not single wire cable. Unfortunately the answer is me.
