Can anyone suggest what brand or wires should I buy. I will most likely use Amazon as it will ship the fastest.
Talking to the contractor he said to get 250ft.
In wall wires use in wall rated wire like this:
Do not use this:
If it is going to be run in the ground or outside and not just attached to the side of the house you should use direct burial cable like this:
There is no difference in performance except that the in wall and direct burial wire is twisted and would be less prone to act like an antenna and pick up interference (at short distance probably not a big deal). However there is a difference to insurance agents if you have a fire and don't have wire rated to code. If the fire is related to your AV equipment they refuse to pay the claim. I have seen this happen personally. An elderly man had wired 8 pairs of speakers to his very modest Sony stereo receiver without an impedance matching circuit. His receiver caught fire and burned up there living room. Insurance company refused to pay the claim because it wasn't the proper wire, even though the wire had nothing to do with the cause of the fire.
For not much more money use the wire that you are supposed to for the intended use.
