Does the"quality" of jumpers affect the sound?

Make sure you speakers are capable of this first. FWIW, my speakers (Verity Audio Parsifal Encore's) have jumpers, but are not bi-wireable or bi-ampable. They have one crossover, and it is in the bass module. My speakers were designed for the speaker cables to be attached to the woofer module. Otherwise the mid/tweeter would be run full range, which could damage the drivers.

So know your speakers design before trying some of these suggestions.

Anyone ever try wiring the positive to the tweeter and negative to the bass while using jumpers?

Yes, that is the best way to single-wire if you have to. Otherwise, whichever part of the speaker you connect directly to will sound noticeably better than the part that gets its sound via the jumpers. The + hi/- one low method results in the most balanced sound across the entire speaker.

Jumper quality matters, but it doesn't take much to have very good quality for such short pieces.

Has anyone here tried the Cardas jumpers? I bought two sets of the Rhodium plated coppers and like them quite a bit but wish I would have just gotten the pure coppers to be honest.

Notwithstanding the statements about jumpers making a difference and connecting at either the high or low side, cross wiring + to hi and - to low, cannot make any difference since the current is AC and effectively the + & - change continuously according to the frequency.

Try it and use your ears to determine what happens. You and anyone else who actually does the experiment, will easily hear the difference. It's not that subtle.

We are forced to do it here on a regular basis with the Linn Akurate speakers which have a true 5-way split crossover makeing them quin-wireable. When choosing the best way to hook up our two speaker cables, there are obvious differences depending on which drivers get the direct connection.

The point you make about AC has nothing to do with the reason that a direct connection sounds different from an indirect one. If we were talking about illuminating a light bulb, your analysis would be fine, but the sound we perceive through a stereo system is a much more complex animal. Lots of things matter (are perceivable) in audio that don't matter in other applications.
