Ok, I am doing a wiring job for my sister and right now she has 8 speakers outside, with two receivers. Four speakers to each receiver. I want to put those all together on one receiver, can I do this? Also I need the option of turning two of them off, how do I do this? And finally, I have to run wire to four of the speakers that are about 20-40 feet away from the reciever, what is the best type of wire, or is there a wireless solution to this? Thanks for any help.
