Thanks for the help.
I am trying to learn on my brothers system since mine won't be here for a few weeks. He has a Denon 3805 and I had a couple more questions. What do I set the crossover level? I think the options were 60, 80, 100, 120db? Do I set the sub to 75 on the SPL meter? Where should the volume knob on the sub be set to?

Thanks
