How to hook up tv to my apartments built in surround sound speakers?

Hi, I have a LCD tv I'm trying to hook up to our apartments built in prewired surround sound speakers. There are two audio outlets in the wall , each consisting of one red and one black place to insert what would seem to be speaker wire or audio plugs. What is the name of the necessary cable/wire/plug I need?

You need a stereo receiver. Your TV probably doesn't have the capability of doing audio outputs over the red/black stereo connections. A simple receiver will do, something like this: http://www.bestbuy.com/site/olspage.jsp?skuId=8786361&type=product&id=1205365050011

That's not the one I'm recommending, I'm just saying. Higher end equipment will be able to decode more types of audio formats, such as DTS: MA, but then again you have to have stuff that plays DTS:MA (like Bluray movies). Good brands include Yamaha, Denon, and Onkyo. Those 3 shops also have refurbished stores, so you can get a good unit at a significantly lower price. If you're just looking for simple surround sound, the cheapest receiver that does 5.1 (or 7.1 if you have 7 speakers) will do.

Basically you hook up your cable box to the receiver, and then there should be a video output from your receiver to your TV. If you need another HDMI cable or something, try www.monoprice.com for good cables. They work just as good as the $100 Monster cables.
