need wiring support.

When a speaker has two sets of inputs on each side totaling 4 different connections how many ohms could you run that amp at? Is it possible to wire it to 1 ohm. I have 3 12" audiobahn's and they say they hold 700 watts. I have am orion 1/0 ohm amp 2500w, could I use it for the 3  Audiobahn's to it. Also I have a pair of Rockford Fosgate T1 speakers.They only have an input on each side totaling to two different inputs on each speaker. Which would be better for that amplifier the 3 autobahns or the 2 Rockford Fosgate. Please help me wire them I really don't want to blow them. Thank you.
