The in wall cable has four wires. Would you recommend using two for each speaker post or one for each post and run two speakers of the one cable? Thanks

you can get inwall wiring with 2 wire from other sources.

I already have the axiom. Will one wire per speaker post be enough? It is 14awg.

Generally 14 gauge would be good for most of axioms speakers except over long runs with a 4 ohm speaker.If its already there why not use it?

Greg, one wire per speaker terminal is fine. Be sure to match the receiver output channels to the corresponding speaker(although the different colors should make this obvious).

If the cable run is for one speaker I would use both.
No harm, no loss, you paid for it,why not use it?

Although it isn't entirely clear, it wouldn't appear that Greg would be thinking of using just one cable if he already had two of them installed.

Will run three cables with four wires, one cable each for front left and right plus centre. I will try and double up two wires for each speaker post. I will let you know how I make out.
Will also post some pictures of my homemade rack soon. It contains an emotiva XPA2 and XPA5 both gen. 2, Onkyo 818, OPPO 103D, two monster power conditioners, apple tv and logitech ultimate remote, Rogers HD box, also pull out table on blum self close sliders for laptop.
Thanks everyone

Yes, if you're definitely going to install one 4-conductor cable for each speaker, then there's no good reason not to use two conductors on each speaker terminal. Doubling 14ga conductors results in the resistance of an 11ga conductor. There's no need for this except in extremely long runs, but if you have it, use it.

well, is this so.
you would think, the voltage applied at on end sends the same current down two like wires at 14g how does this make it less resistant ?
It is the same voltage, same resistance, same amount exactly of information, just going down two 14g runs. Both leads are resisting the same.
I can see if you pealed back the sheathing and joined the two wires together you would get an equivalent of 11g though
