Community Reviews

This 12 gauge Amazon Basics speaker wire is a stranded, pure copper option that fits long runs and power hungry home theater setups. It has been used successfully for surround, surround back, Atmos, and even 4 ohm speakers, and the 99.9 percent oxygen free copper is treated as close to as pure as practical. The main caution is that the conductor may not feel like a full true 12 gauge, and the wire does not look especially flexible. For shorter runs or lower power speakers, cheaper 16 gauge is often enough, so this makes the most sense when gauge really matters.

  • buyers who want stranded pure copper speaker wire for typical installs because commenters confirm it's stranded copper and say it worked well for their rear speaker run.

  • home theater owners running surround/surround back/Atmos speaker channels because commenters say it worked fine for powering power-hungry, amplified 4-ohm Arendal speakers.

  • people planning a long speaker run (around 100 ft or more) for power-hungry setups because community guidance says 100-foot+ lengths and "insanely power-hungry speakers" are where 12-gauge is more likely to be needed versus cheaper 16-gauge.

  • installers who are pairing speaker wire with banana plugs because one commenter specifically recommends combining this with banana plugs and says pure copper is what you want.

  • home theater buyers adding in-ceiling Atmos speakers who are trying to match true 12-gauge copper because one commenter returned this after comparing it to actual 12-gauge copper and felt the internal copper amount looked like only about 1/3 to 1/2 as much.

  • buyers who are very skeptical of Amazon Basics product claims because one commenter says they have a difficult time trusting any "Amazon Basics" product.

  • people who need very flexible speaker wire for tight routing because a commenter says it doesn't look very flexible based on review videos.

  • buyers who require strict "true 12-gauge" verification because one commenter argues that if it isn't really 12-gauge, it would be falsely misrepresented and "completely unacceptable under any circumstances."

I used a few reels of this for my surround, surround back and atmos channels. Works fine for powering my power hungry, amplified, 4ohm Arendal speakers.

Quote from AquaVolcano980 View quoted comment :
12 gauge stranded wire should have a conductor diameter of 2.0mm. If you could measure your wire and post the results, that would be helpful to others.
I bought a couple 200' reels of this wire and it is great, you can see for yourselves.



BTW Slickdeals, it's a PITA to post a pic for a reply using a phone.

doesnt look that flexible from one of the review videos, though still decent price for 12guage.

I received it. The wire I got is 65 seperate 30 gauge conductors with an average of about 0.25 mm diameter per conductor, so total cross-sectional area is ~3.19 mm^2. From the charts [solaris-shop.com], that's close enough to 12 gauge for me since I'm not using it to build an electric space station.

I'm picking up the 200 feet of 14 gauge, too.

Yep, don't buy this wire if flexible is top of the list.
