In a balanced system, the 2 wires that deliver the signal, will be opposite of each other relative to the ground. In an "unbalanced" output, one of the signal wires is the ground, so the full signal is delivered relative to the ground.
When you get this thing connected directly, you may only get 1/2 of the volume from the amp.

So what do I need to do to make the signal from the sound card balanced? Would it be possible to get another amp that has RCA inputs, hook the carputer up to that, and then hook up that amp to the stock amp?
