Out doors I have always ran SOOW. You’ll never hear the difference until you roll over the cable a couple of times with 300lb subs on casters. It will tear up a standard anything other than 600vac SOOW in armor. Some of my 50 footers double (4/12) bass cable are 35-40 years old. You can just about hit them with a lawn mower and it will not only keep working, it will still sound good too. 99.999 pure copper, fine stand, very flexible. Heavy copper works on everything.
I roll out heavy speakers in the summer and I have a few outdoor speakers.. To roll out plug in and listen to music under 5 minutes. They are stupid proof speakers too.
