I am just trying to come to grips with possibilities using my new Asus Xonar DG Soundcard. It's a well reviewed but low cost card @ $28 & I selected it to replace my failed on-board Card. So I now have my desktop amplified speakers set up, but they are budget variety & somewhat limited, although I do not expect or need high volume. I happen to have several small (ex car) amps, & several pairs of reasonably sized reasonable quality speakers, so I thought "what about a 4 speaker set up"? Is this possible & how can it be wired up? If done this way should I hook up a double gang log pot to control volume rather than use the on screen slide control which is not that easy when you are doing other things.
