Connecting normal sterio speakers to rig?

Is there a cheap way to do this? I have 2 large speakers that I don't use and then 2 smaller ones that attack to a little boom-box. Is there any way to connect those to my comp?

Other then the fact that you need some sort of an amplifier (like the boom box)....... all you need is a minijack to RCA patch cable to connect the line out from the sound card to the aux input (or even the tape input) on the boom box

Yeah man!
I use two big Good quality stereo speakers powered by a 220watt power amp connected to the pc via minijack/ rca adapter.

I will never go back to pc speakers again!
