The goal is to have my xbox as my car pc. I have altered my xbox so i could use apps and other things. Its essentially a computer. (Please don't ask how) I want to use just a screen and not a head unit. The xbox has rca jacks out so how would I connect my orriginal speakers using the rca jack. Is there some kind of converter or somthing so i don't have to buy an expensive radio thats fugly anyway.
