Actually, it's smaller than #4.

My bad; you're right. #6 or smaller. D-oh!

I called the manufacture. I am good with #6 after the sub/gfci.

Don't forget that smaller than #6 must be white, not re-colored white.

Did they tell you that you could use #8 for 50 amps?

No, the spa manual requires #6 for a 50 amp’s first 100’ and #8 for 40 amp’s first 100’.
