I bought the Sony HT-IV300 home theatre system 3 years back.
Specifications ( Impedance levels are mentioned)
For the front speakers, just used the default surrounding speaker wires ( impedance of front = surrounding = 3 ohm), so no worries about them.
I would like to install the surrounding(rear) speakers of 3-ohm impedance on the walls. The wires are concealed. So, I need to buy the wires to extend up to 30 feet for each speaker.
Online references/readings lead to confusion as everyone stands on their own standard.
-
Can you guys help me to buy the right wire with right AWG and with a wire gauge chart for distances vs ohm ?
-
Shall I simply buy 14 gauge wire without thinking too much technical?
-
As the wires are concealed, should i think of oxygen free copper wires?
Am i really thinking too much?

I would just install 14 gauge wire, it will be more than adequate at 30 feet.
Look for a reputable brand that's made for audio and rated CL2 for in-wall installation. Any decent speaker wire will be made with fine strands and sufficient purity for your surround system.
You can spend a lot more on speaker wire, but you won't hear any difference.
