One thing to check first.
You say the TV has the needed red/white analog outputs. That's good.
But, you might want to assure that they are variable: That's to say that when you mute the speakers, the TV's volume control works on the red/white jacks, too. Otherwise, you may have to adjust the voume via the amp.
Not all TV's do. I have one of each, both of the same brand.
