Accessories For Iphone 4

How do I connect my iPhone 4 to my TV so I can listen to music from my Bose speakers?
Hello, I have the Bose CineMate II speakers for my HDTV and an iPhone 4. I want to know what accessories I need to purchase so that I am able to connect my iPhone to the TV or the speakers so that I can listen to music from my phone out of those speakers. Looking for the cheapest possible way, thank you.
It will be loud maybe… Doesn’t mean it will be a good quality.

These work.
There’s some that plug into the headphones jack too… and the other end would plug into male ended rca cables.
