11 awg would have less resistance than 14 awg. I use 12 awg for all my applications, just because I like to. smile

exactly,

but, two 14g wires in separate sheathing carrying current and twisted together one te ends, does not make it less resistant. You still have two separate 14g wires with the same resistance carrying identical loads. Unless you peal off the sheathing and join them together.

I think it is a moot point to use the two wires, unless of course your going to bi-wire or use it to bi amp. There is no advantage to twisting the two ends together. Unless I am wrong

Troy I cant give you a technical response , I will leave that to JohnK . I will say that electricity takes the path of least resistance, so more wire surface for the electricity to travel the least resistance. In this case ,unless these speaker wires are stupid long there will NOT be any benefit to doubling the wires. At most he will gain redundancy so if one wire fails the other will back it up. Google home made speaker wires in images you will see people braid together cat5 cable to make fancy speaker wires.

that's the issue there is no least resistant path, both wires are 14awg. Also, if they are twisted together on both ends it will flow down both wires with the same voltage .
It would be like tying one end together and putting it into a light socket the holding onto the other ends of the two wires in each hand. you will get a shock one both hands, not just one.

The only way your going to make it less resistant, with that wire would be to strip it , braid the whole run together into one making it bigger. That cannot be done though. Or run higher quality wire, like gold , that will get you less resistance lol.
But, I am pretty sure twisting the two ends together and running current down using both like that is no benefit at all, unless your plan is to use it as a bi-amp or Bi-wire situation.

Have a look at this article, Troy, particularly the bit titled Cable Electrical Factors and How They Affect the Sound - Colin Miller. It does in fact lower the resistance, since you are essentially creating a (very low resistance) parallel circuit.

In EE 101 we learned that two identical resistances in parallel create a resistance of one half the amount. That is because the current flow divides half into each wire. R in parallel with R equals .5R. Total current flow of course is determined primarily by the impedance of the speaker. Voltage drop across the wires from end to end will drop to about half what it was with one wire.

My early EE courses were over 40 years ago; but I do think the basics still hold.

Troy, "doubling wire drops three gauges" is an accepted principle of wire technology. You're correct that completely stripping the wires and binding the conductors together would accomplish this, but you're not grasping the fact that binding them together just at each end accomplishes the same electrical result. The conductors become a single wire(including the portions not in physical contact with each other)with a combined cross sectional area equal to the sum of the areas of the previously individual wires(i.e., double the area). Since the convention in designating wire gauges is that a wire with twice the cross sectional area of another is three gauges lower, the doubled wires likewise are likewise termed a wire three gauges lower. The electrical result of doubling the cross sectional area is halving the resistance.

Again, this is a well-established procedure.

I know it's not the same exactly but the simplest I've heard it explained by a Cisco instructor was "Even if they are all the same size, 4 small pipes will drain a tank faster than two small pipes."

Well I doubled up the wires at the ends and everything is up and running. Will try and post some picks on the weekend of my homemade rack. Thanks guys

I wouldn't connect both wires. You want prevent circulating currents which may induce unwanted voltages and noise due to differences in resistance. While this may actually not be in effect here, the chance of it outweighs any benefit.
