The crossover will be worked out with you ears as to what sounds best. For the sub amp, usually 70-80 hz low pass works fairly well. For the infinity perfects, which I assume have passive crossovers with them, you can just set the highpass around 70-80 as well, but again your ears will dictate. Plus you may have to raise it up if the mids can't play that low very well, or you can lower it (and lower the sub crossover along with it) if they can handle going lower without bottoming out. Same with the rear channels to the coaxials. Don't need to use the subsonic on the 4 channel.

Oh, and the range would be x1. if you put it x10, the crossover would become 1,000 hz if you had it set at 100. It just multiplies whatever you set the crossover at.

Thank you that answers a lot of questions
