BiWire will make little or no difference.
This is my Opinion, so the next post will be from someone who noticed 'transcendent improvements with biwire'......

IOW,

Try it and see. No other way to tell.....for you.

I liked biwiring better than shotgun, but most important is to have large wire to the woofers to me; I like to get the full bass.

Also, to me, biwiring may help a little, passive bi-amping helped a lot for dynamics, etc, and then active bi-amping helped a little more on realism and clarity.

If you want a (significant) change, bi-amp.

  Passive or active biamp. I have always found passive biamp to sound worse than a single good amp

      Biamp is an interesting, if somewhat expensive proposition.
      Ratio of amp power for hi/lo depends to a large extent on crossover frequency while other amp characteristics like what I call 'latency' can effect phase / delay which materially effects image and coherence of soundfield. I define latency as the time it takes an input signal to propogate thru the amp to the speaker outputs.
      For my .05$ I'd try to use either idential amps or amps from the same 'family' to avoid issues which you can have with, for example, SS on bottom and tube on top.
      
      A couple pair of Pass monos would be my starting point...soon after winning the lotto. For my 1.6s? I'd consider the 100watt 'a' amps from Pass.
      
      And yes, Active would be the goal for me, too. But that said, the starting point would be to mimic the STOCK crossover as closely as possible.
      You might also need some measuring instruments....a scope, signal generator and 2 or more DVMs, the right software and a couple cal'd microphones.....to start.

I also have found that a single cable on my 3.6's has always been better than my attempts at bi-wiring. But since he has the cables just experiment and use whatever sounds better. But give each hookup a good week or two of listening to determine what he likes

  Biwiring can alter the amplitude response because it inserts a resistance between the two legs of the crossover. I've seen a paper on the effects and they could be audible, but that, of course, would depend on the specifics of the cables. I think it's best to assume absent evidence to the contrary that the designers knew what they were doing when they designed their crossovers, and that any change is more likely to be detrimental than beneficial. And agree with those who said that bi-amping is the way to go.
