Dedicated 20a lines, 125 feet distance, which gauge wire to run?

Want to set up 4x dedicated 20-amp lines for my hifi system. The distance from the outlets to the breaker box is about 125 feet. What wires should I use? 10, 8, or 6 gauge? And should they be solid or stranded? If you could be as specific as possible that would be appreciated (brands, links, etc), as I am out of my depth here. The wire will need to run underground for a good portion, and then into craw space, if that makes any difference.

Do you have room to put a 60 breaker in your main panel? If so ,run 6 gauge wire to a 60 amp sub panel, then run your receptacles from there.

Since you’re out of your depth I hope you get a licensed electrician. You will need direct burial or UF wire underground. If you put in a 60 amp sub panel use 4 awg from main to sub then at least 12 awg to the outlets. 6awg is only rated for 55 amp you need at least 4 awg for a 60 amp sub panel. Talk to an electrician.

I just did a search & came up with this; While it’s common to use a 6-gauge wire for 60-amp breakers in practice, it’s best to use a 4-gauge wire if you’re installing a 60-amp subpanel. 60-amp breaker panels controlling several circuits can draw a max of 60 amps before the subpanel breaker trips. I doubt you’ll ever draw 60 amps @ any giving time.

It doesn't matter what anyone doubts what matters is passing inspection. Call an electrician.
