Bi Wiring for speakers question


I've done some research on bi wiring speakers and have noted that some people are apparently using a speaker cable with 4 banana connectors on one end but only 2 on the other end.  I'm guessing that the side with 2 banana's is connected to the Amp or Receiver and the side with 4 to the speakers.

Anyone tried this and does it work as well as using 4 connectors on each side?  Seems to me that using all four speaker outputs on the amp is the right way to do it but if it will work with just one pair of speaker outputs then who am I to judge?

I've had great success running seperate brands of cables from the 2 binding posts on each Mono Block to Speakers. Allows you to run a seperate cable better suited for bass and seperate cable better suited for mid's/ highs.
When I installed four pairs of AQ Type 4 into my system, I noted a big improvement in the bass in my Castle Conway 3 speakers.  I put on the album Love Beach by Emerson, Lake and Palmer as a test.  Has some very low bass notes in a couple of the songs.  My Mirage OM 10's could always play them even when not bi wired but the Castle's were not.  After bi wiring I could suddenly hear bass notes on that album on the Castle's that previously were unheard.  Overall the sound is much better than with two pairs of cables.
Separate brands?  In other words, use AQ Type 4 for one speaker and some other brand for the other speaker?  Or do I use one brand for the high end and the other brand for the low end?  Sounds odd.
@will62  Never run different brands or cable topologies when biwiring.  You want the same cables for both biwire runs.  If not you risk defeating one of the primary objectives of a biwire designed speaker...that of optimizing the function the speaker's crossover network by presenting the music signal to both parts of the crossover in concert.
