I just bought a Polk RM6750 speaker system and a Onkyo TXSR304. I am really completely new to this, and I have no idea how to get this set up. I was reading the manual on the Polk website, but I do not really understand the dynamics of what else (such as wires, etc) that I need to purchase and how to connect everything. I have an HDTV and a ps3, and Im just looking to use all of these together to watch movies and play games. I would really appreciate it if someone could help me figure out what I need to buy (I was looking around on monoprice.com but I couldn't figure out what I need) and how to set everything up. I am using this in my apartment living room which is about 18X12. Thank you so much for your help!
