Hi Dave,
The crossovers in the Sig 3 present a wicked load to the amplifier. I experimented everyway possible with those speakers. The best results are to open up the terminal box on the back. Unscrew the leads at the bass terminal (lower) and connect them to the upper post. Run one set of speaker wires to the upper post. The bi-wire jumper does not work well on that speaker- nor does bi-wiring. I would take a look at the Kimber brand of cabling to use with that speaker. I only tried the Nordost Red Dawn interconnect. That had a strange sound in the highs and the bass was incredibly powerful. Try a lowly pair of PBJ and some 8TC.
good luck
