I'm planning to do the same. I'm a newbie when it comes to setting up home theater systems. I just would like to add few more questions:
1. Is there a way to use the hdmi instead of the rca as a left/right speakers in a 5.1 setup?
2. Using RCA, will the volume levels sync up with the other speakers (connected to the receiver) or it has a separate control as it is?
3. Is it better to conn3ct the sub(powered sub) to the receiver or directly to the Fives?
Thanks a lot!!
