Is there a way to do this with the empeg/amp combo? So that from where I sit, each speaker is hitting my ears at/about the same time? Or something to help me setup the EQ....To be honest, I am partially deaf in my left ear (been that way since i was a kind but my dad thought i was just ignoring him!) so it may not be a good way to do it...

What I do is basically is similar to what many people who compete due for tuning their systems. Various test discs are available that are specifically designed for Car Audio setup -- the one I use is the AutoSound series (I think Crutchfield still sells them, that is where i picked 'em up from). There are 4 CD's total, and CD 2 specifically deals with imaging. Each one has notes on the tracks and how to use 'em to your advantage.
To use them with the empeg, you would have to convert them at the highest quality setting for .Mp3's, or hook a CD player up to the AUX input.
Hope this helps ya out!
