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?
