i bought a new house. It is wired for 5.1 surround sound. I am trying to buy a samsung system since I have a gift card that will pay for them and the store doesnt have good stuff like stand alone receivers. So i am looking at the Samsung HT-E5400. My problem is that the wires already in the walls are just plain old speaker cables. On the samsung, the speaker side accepts speaker cables but the other side has some sort of plug on it that goes into the reciever. Can I just cut the plugs off of the cables that come with the samsung and attach them to the receiver side of my cables? Are there any problems I could run into other than voiding the warrenty on the thing?
