How to hookup multiple speakers to an old RCA F27100AK?

So i have that old T.V. and i have my xbox 360 slim hooked up to it. I am using 2 external speakers through the "bare wire plug in" (i don't know what it is actually called, but you put bare wire into the tv through these two plugs). But now i have 3 more speakers i would like to hook up as well. They have the standard audio plugs (red/white). But i have no idea how to do that. Please help, or refer me to a helpful webpage with it's manual, because i no longer have it. Thanks!
