Widening the Stereo Image

[Punx]

I did some searching on the DUC but couldn't quite track down what I was looking for so any links you guys mave have to other threads would be appreciated. Anyway, the question I have is how do you go about getting that "outside the speakers" sound? I've heard certain recordings that have percussion or maybe even guitar that appears to be outside of the regular field. I heard this effect on an old song The Cars did so I know it wasn't mixed in 5.1 or anything like that. I know they make plug ins for this knd of thing, but obviously I don't have one. So i was curious if there were some other tricks to achieve this effect. Any suggetstion are appreciated.
