Re: Questions about speaker impedence on an Onkyo Receiver...
Several of the onkyo recievers are designed to handle 4 ohm speakers. That's one of the reasons I like them. Most home recievers are only 8 or maybe 6 ohm. Double check that is the specs for all the speaker outputs, not just the main L and R.
I think the best way would be to wire each set of 4 speakers as an 8 ohm load, because there will be additional impedence rise due to the length of wire. 8 ohm + 8 ohm (parallel) = 4 ohm. 2 pairs of 4 ohm sets wired in series, 4 ohm + 4 Ohm (series) = 8 ohms. You can use terminal/barrier strips from RS to keep the wiring neat, or just ghetto twist the wires as needed.
Wire each of the 4 sets of 4 speakers onto the L,R (front), L,R (rear). That would still leave you with an easy 8 ohm load and several other speaker channels for outdoor speakers, subs or whatever. With that many speakers and lots of wire, you will have large impedence swings and still leave the onkyo lots of room to handle it.
