Anybody know anything about building amps?

I've recently come across some fairly nice sized speakers that I'd like to hook to my TV.

But, I thought it would be cool to build an amp for them myself. They're unpowered, which means there needs to be some sort of go-between from my TV to the speakers to give them enough power.

I've done a little googling, but the most I am coming across is little altoids amps for headphones - which isn't what I'm after.

My thought is though that I might be able to take one of those schematics and upgrade the parts to a higher voltage... I'm not sure really.

Any thoughts are welcome!
