In Total, about 100 Watts I think.
This wouldn't be a smart investment if you ask me, the sound quality won't be great and most likely won't get very loud or give off clear dialogue.
I looked to see if I can find something better, and within that price range and on Amazon there is a Samsung Blu Ray Home Theater System HT-J4100 that's a really good deal that's Certified Refurbished from Samsung. It's normally $299 but it's marked down to $169.99 with free shipping.
The player not only plays Blu Rays but DVD's in Full HD, and it has 1000 watts!
