altec lansing bi-amp. crossover

I have this pair of altec lansing speakers and they are different from any other I have ever owned. each speaker has a 160 watt (RMS) cross over amp.installed. They were not put in at the factory. They also have the original crossovers but they are not hooked up. The speakers hook ups are different to. I am totally confused and want to hear these monsters play. Could somebody please help. Thank You, Terry Peters
