RCA Audio lead adapter question

Hi, I want to connect both my Xbox 360 and PC to my Hi-Fi. The Hi-Fi has one RCA (I think thats what it's called, the red and white plugs), and both the PC audio cable I have and the VGA adapter for my xbox 360 use the rca cable to connect for audio. Is there an adapter that will allow me to plug both the PC and xbox 360 RCA plugs into the Hi-Fi at the same time? I wouldn't use them both at the same time because the Xbox 360 and PC also share a monitor so I don't use them together, it would just be alot more conveinient that having to reach behind the Hi-Fi every thime I want to switch between the two.
Cheers!

 

You may need something like this. I am unaware of the type of connections you are currently using, but I use these to piggyback rca to inputs.http://accessories.rca.com/RCAAccessories/images/AH96PB-large.jpg

I had this same issue. I found a small switch box for less than $20.00 at of all places, Wal-mart. It worked great. It had three sets of RCA inputs and one output and a selector switch. Super simple, and it was in the audio section. I have since moved up to a really nice remote controlled one I found at a computer store for about $50. I like it because I can use my remote to switch the input without haveing to ever leave my chair. Yea lazy I know>
