I'm sure it's a bit out of my league, but how would you go about doing this? I'm planning on swapping the speakers out in my 5150 combo for a Governor and a Wizard that I have laying around unused. The Wizard was used a while in my 4x12, but still isn't quite through loosening up, and the Governor is brand new. If I use the stereo trick, could I run the line out from my computer to the effects return of the amp, or is there a better way?
