Axiom Home Page Forums General Discussion Stereo Subwoofer Hookup?

OK, I am getting some Axiom M3s to be paired up with an old 80W Kenwood KA-6100 and I am probably going to want to add a subwoofer to my system later on (not so much for movies, but for music). Do I have to buy a new amplifier to do this? If not, will it sound better with a new, digital amp?

I have heard a lot about subwoofer hookup, almost none of which I understand. My big question is can it be hooked up with my old 2-channel amp? By the way, I am thinking about the EP-125 as a sub.

I am not really concentrating on getting boomy bass, rather, I just want sharp, clean bass. I hope this subwoofer will do it for me. It seems to get good reviews, anyhow.
