Then it's a lie. Don't pay more than $50 for it. Sony and Pyramid likes to play with numbers. They turn 22w rms amp into 250w. You will have to very closely to find the actual power. Probably located somewhere in the manual where no one will look. Don't waste your money on Sony. Trust me, you will regret it. If you look in this forum, you will find a thread "Why Sony Sucks". Read up on it and you will find Sony owners complaining.
