I am installing a surround sound system. I am placing the speaker wire inside the walls near electrical wires.
I'm no expert on electronic theory, but I would say better be safe than sorry. 12 inch spacing should be just fine.
Normally they do not pick up noise, unless you are using florescent lights in the house. The farther from florescent lights the better.
No, the impedance is very low and it is virtually impossible to get any noise from a power wire. If anyone else says different then they don't know crap about electronic theory and practice.
the warmth duct in elementary terms gets to approximately a hundred and ten°F, properly below the ignition element the cord. If it is not too warm for a human to the touch it is not too warm for the cord. Heating ducts are many times electrically related to Earth floor. A harm interior the insulation, a foul splice, or uncovered splice ought to reason a short. A partial short could reason arcing. AWG24 is small. it is in simple terms stable for various Watts. Sending intense means interior the path of the cord reasons it to warmth up, and the insulation fails, and if it keeps the steel itself can burn. Melted insulation from small cord like that could seize fireplace from spark or adequate warmth. The ignition element isn't very intense. i will truthfully reason AWG24 to seize fireplace. putting enjoyed ones chemical aspects on the cord does not going reason a fireplace. Acetone, alcohol, and such dry at as quickly as, there'd be no longer something left to reason a fireplace.
You are best off not keeping them together although the signal you would be sending is not as low as 60 Hz you could get common mode coupling that you wouldn't probably hear but would cause a sap in performance. Any time You pass any electrical signal or EMF bias thru a wire it radiates energy in a predictable pattern around a wire or conductor. Most Consumer electronics companies don't do Electromagnetic Compatibility testing on their devices, so from time to time you will run into a problem with signal interference. It would be advisable to not make the shielding or signal coupling of you devices work harder than they have to. Use good interconnects and if it is a real concern and you can't run them apart use a conduit ( metal only) as a shield around the speaker cables. Using conduit for both and keeping apart by at least 12-16 in would be the best possible solution. Also as a side note: make sure to use the proper in wall rated speaker cable applicable to you local code.
