No sound from my receiver?

I'm looking to setup a decent surround sound system with a Sony HTIB DAVHDZ273 and a Sony A/V Receiver?

• I have a target gift card. So I have to use it at Target obviously. This system was the one that made the most sense to purchase, and with the size of my living room, was also the best. It's not big and powerful, but seems as if it'd be enough. However, I'm looking to hook up an Xbox 360 via Component, A Wii via Component, a DVD player via HDMI (not the one that comes with it, I have a better Upconverting player), a cable box with HDMI and an original Xbox via composite. If I purchase the receiver mentioned below, is that enough wattage to power the speakers? I'm hoping the subwoofer is powered on it's own. And if it is, I believe the receiver will be enough. Any input will be greatly appreciated.

Although they don't sell the receiver at target, I am still willing to purchase that from my own pocket. Thanks!

• Answer:

  Well in your budget range if you can find an Onkyo system they are better, but if you feel it's good enough I guess I can live with it. Some of us love audio and wouldn't be caught dead buying that system. Doesn't target sell food? So I would live off the target card and spend food money on some great towers and a receiver. But for you it's probably fine. Just as long as you aren't buying Bose I won't balk too much. FYI those go for sub 200 dollars on ebay.
