I have heard nothing about hooking up a amp to a computer... I have pulled the ittle computer amp out of the computer... so how would I hook up an amp and subs to it... or just subs?

I don't understand your question. Are you trying to hook a computer speaker package up to your computer? Or your computer to your home stereo amp (reciever)?

Well I don't know, I have heard something about hooking up my car subwoofers to some part of a computer?? Or something... or do you know how I could hook up my subs in my room somehow and make them hit hard?

Do you currently have a set of amplified speakers and subwoofer hooked up to your soundcard?

Well I don't know anything about a computer... my dad has an old computer and thiere is this thing inside it, I think it's a sound card, but I don't know... uhm, I have a 450 watt amp, and I have a 4 1200 watt subs I only want to run 1 or 2 though... how would I do it...
