what speaker wire is better 12 gauge or 14 gauge and does this look like a good sub wire replacement http://www.monoprice.com/products/pr...eq=1&format=2?

Neither, for runs of less than a few dozen feet.

Sub cable is fine. 14AWG is fine.

12 gauge. Bigger is better. But how far are you going, what are you powering? You may not need it.

@ 20 - 30' 14 AWG is adequate. I'd assume he's powering speakers.

Bigger may be "better", but not always necessary.

Agree. Thus what he's powering, and that was intended about the speaker impedance. The two main variables are distance, and the impedance you're driving. Really low impedance, or long distance and you need a very large gauge wire, which is why in very large distributed audio systems it's usually a constant voltage system with transformers at each speaker since it's way more efficient that way and you're not forced to run absurdly large gauge wire everywhere.

You should notice right away if it's quality wire wheather it's 14-12 gauge.

It should have more strans witch in turn are softer and much thinner then cheap stuff.

This provides a lower resisistents and thats what your paying for. In return your amp won't work as hard resulting in a cooler running amp

As far as i know, strands only assist in flexibility.

Totally agreed. Wire gauge is based on the cross sectional area of copper. Conductivity is based on the same.

Contrary to popular belief, stranding does not have much to do with the ability of wire to handle high frequencies. And, high frequency signal handling such as it may be affected by wire, is not an issue in the lengths of cable commonly used in home audio systems, or even within a house.

Agreed, and by implication resistance to breaking. However, cable breakage is primarily determined by how strain is relieved at bending points.

Yup. And typically, most home speakers are rated at 8 Ohms. Most receivers/amps are rated to drive 8 Ohms (or 6 Ohms based on how the manufacturer wants to enhance their specs). The impedance rating is an "average" and not a constant. Impedance can/does change depending on the the driven signal(s).
