Bi wiring v single run w jumpers

"Also is the top running the tweetrer or the mid and tweeter? That is another variable HATE IT."

If the speakers have jumpers on the binding posts, remove them. Then just plug speaker cables in to just one pair of binding posts and see what drivers are playing. As for the rest of it, you'll just have to experiment and see what works best. There's just too many variables and no one can know what your personal preference is.

I agree with Michael (Swampwalker) and ZD. I would add that some of those 1,324,991.6666 answers would involve four separate sub-options within Options 1 and 2:

1)Connecting to the top terminals.
2)Connecting to the bottom terminals.
3)Connecting the + conductor to the top terminal and the - conductor to the bottom terminal. Some users here have actually reported that to be preferable to the previous two sub-options.
4)Connecting the - conductor to the top terminal and the + conductor to the bottom terminal. Ditto the second sentence of sub-option 3.

You may find this thread about biwiring and this one to be of interest. As I said therein:

Having followed many prior threads that have addressed this question, I can say unequivocally that a clear consensus has emerged. That consensus can be stated as follows:

It may or may not make a difference. If it makes a difference, it may or may not be for the better.

Not much to add to these three excellent answers. I would only question how Michael came up with two-thirds of an answer. ;^)

No one can tell you what will work best for you, just as no one can tell you what your favorite adult beverage is.
You simply have to try for yourself, and make your own decision.

Zd 542 I know which one runs what drivers My point was it is just another issue . In other words if the top just drives the tweeter I would be inclined to go to the bottom but if the top drives the mid and tweeter i would put my cables to the top as it wwould have more effect on what I hear. Under 250HZ is more feel then anything

3)Connecting the + conductor to the top terminal and the - conductor to the bottom terminal. Some users here have actually reported that to be preferable to the previous two sub-options.

This is one I see in pictures and am wondering what it really does??

If the connections are made to either the bottom two terminals or the top two terminals (as in sub-options 1 and 2), the current path between the amp and one section of the speaker would include two jumpers, while the current path between the amp and the other section of the speaker would include no jumpers.

If the connections are made to a diagonal pair of terminals (as in sub-options 3 and 4), the current path between the amp and each of the two sections of the speaker would include one jumper.

Assuming good contact integrity in all of those cases, and assuming that the length of the jumpers is minimal and that they are of decent quality, I can think of no reason why that difference between the two cases would result in sonics that are perceptibly different. But who knows?
