I came across a used Yamaha NX-SW300 sub/amp for cheap. It's designed to hook up only to a Yamaha DVD/receiver using a cord that looks like a VGA form factor. The signal comes from the receiver into this sub/amp and the 5 other speakers hook into it.
Does anyone know a way to hack this so that it can be used with any receiver output? Any idea what the map of the "VGA" pins is?
