How can I drive a very large passive subwoofer?

My system is comprised of a Mac C-28 preamp, and a Mac 2200 power amp. As you guys know their is no subwoofer out on the preamp. I did buy a nice Emotiva mono amp to hopefully use to drive the sub. I just don't know what to use as an input into the mono amp. Theirs also the issue of feeding only low frequencies into the sub...........Can anyone help me.......HELP!!!!!!!!! Gene

You could, alternatively, sell the Emotiva amp and get something like the Crown XLS Series amp. They have big power capability and built-in crossover. Do a Google search for Crown XLS-1500, XLS-2000, etc...

The Crown XLS Series amps may be an viable alternative, if you can stand the noise that fans make, in your listening room. Personally, I've found that extraneous noise, even at a subliminal level, masks detail.
