Yes, you can. On most motherboards, the on-board sound has a mic 1 (pink) a Line-in (blue) and a Line-out (for speakers, green). With the software for your audio drivers, you can set the Line-in (blue) jack to Line-out. That way, you will have sound coming out of both.
Most soundcards have a "versa" jack which you can also use for more speakers.
My friend had a 2.1 speaker setup (2 speakers and a sub) that he gave me. Now, the sub is pretty nice, but the speakers blow...my two speakers were better. So, I put my good speakers into the Line-out, and put the sub to the versa jack (which I programmed to Line-out. I can control sound levels to just my sub, and speakers independantly now.
If that is not an option, you could also purchase a Y-splitter.
