Extension cable for connecting satellites in MX 5021

I find that the length of the wires that connect the satellites to the subwoofer are not as long as I want it. I want to buy longer wires. Can someone suggest places from where I can find the same and what specs from the wires will I need to provide to get ones that are suitable for the connection. I looked at the wire and it the following thing written on it:

E202313 AWM 2468 80°C 20AWG VW-1 AWM 1 A 80°C 20AWG 300V FT1 K00 WAY

Help will be greatly appreciated as I don't have much knowledge regarding this thing.
