2005 Aspect TV Connection

[IBHIPRU2?]

I recently removed my analog SONY TV to replace it with an LCD digital model. In addition to removing the main antenna cable and audio/video cables, I found another pair of RCA cables (red and white) attached. I have absolutely no idea what these are for. They were obviously a Winnbago add on as the cables are wired into the TV and not a part of the stock unit. Any idea what these connections are for and what the impact would be of ignoring them when I install the new TV.

Ok, I think I figured out what those two audio jacks are for. I failed to mention that I have surround sound. Normally, surround sound speakers are attached through a receiver. Since I have no receiver, the surround sound speaker have to be connected directly from the TV. The question now is how do I get surround sound if I replace the TV
