The SXa100's will take 1/4 inch or XLR, but use the XLR out of the Mackie sub. It's balanced that way, and there will be less chance for noise.

[B] How much cable? [B]
Don't use 50 feet of XLR cable unless you're running to a snake somewhere other than the stage area. 20-30 foot cables are plenty. The shorter, the better for signal strength.

[B]Monster/planet waves...or a lesser quality cable anyone can recommend?[B]

Use high quality cables, but the expense of the monster cables is probably not nessisary. I use them in my studio, but not on the road. If the money is not an issue, by all means get the monster, but for the "real world" you will not hear enough of a difference, if ANY.
