@bstatmeister I'll try to answer your questions as clearly as I am able. The "pigtail" is the interconnect cable coming out of the M5-HP. You plug your preamp main out interconnect in the one side of the rectangular M5-HP and then the "pigtail" end plugs into the input jacks on the back of your power amplifier. Before doing all of that plugging in, you need to open the crossover box and find the tiny "dip switches" In my case my amp has a 100k ohm input impedance. I have my M5-HP set at one setting below that which is 75k. The manual suggests that you try to the actual input impedance setting of your amp and one below, I believe. For me, that one step below gave me the most seamless integration of the subwoofers into my system.
Hope this helps!
PS I would take the Samson out and use unbalanced cables. If you need to purchase a good pair of cables, they are around including, of course, here on Audiogon.
