speaker wire - did I get too small of a gauge?

Bought some 16 gauge outdoor speaker wire, 4x 60ft runs to some Yamaha 6 ohm speakers controlled by 2x Sonos Amps.

These guys:



Before buying I researched quickly and bought 16 gauge wire based on this Sonos article:


Once I stripped the wire I started second guessing myself, and now I’m wondering if I should have gotten 14 gauge based on some other things I’ve read.

I could pull new wire fairly easily since I haven’t tied everything down yet.  Should I upgrade to 14 gauge, or should 16 gauge be sufficient?

For less than 80 ft runs, Sonos recommends 16 gauge wire, so you are good.

Are you connecting more than one pair to each Amp? I believe Sonos recommends 8 ohm speakers if you are connecting more than one pair. https://support.sonos.com/s/article/4730?language=en_US

No, 1 pair of speakers per Amp.

My concern is all these other charts out there that say 16 gauge is not sufficient, like this:


Why the discrepancy?

Thanks guys.  I decided to leave it.  Quality seems good considering the speakers and volume level is more than enough.
