Great wire, great price
Size: 100-Foot, Style: 14-Gauge
There is something about this wire that makes me buy it again and again, and makes me feel like it’s a great value! it’s pure copper strands and it feels, looks solid and as good as anything I ever bought for the sound transmission
The cover is thick, but the wire is still flexible. Looks professional and the white looks better than the old school copper look. Getting the protective sleeve off is a bit of challenge but for me it’s worth it. Have a utility knife, wire strippers and if you have weaker hands, a pair of pliers or something to grip it with to remove from covering wires. It’s worth the effort to me as the results feel solid
I use this with my higher end vintage M&K, Sansui, Pioneer, Timeframe, and other amps, speakers and to my ears, it delivers simple, clean sound at a great price. Don’t buy the hype, buy good wire and call it a day. This 14 gauge even works well with clip posts like on my Sansui 9090DB. 👌
Only thing I would do different, buy the 200ft if you are hooking up Atmos or have multiple equipment. This is my third 100ft in as many months, Lol

Excellent Quality Speaker Wire for A Great Price!
Size: 100-Foot, Style: 14-Gauge
I recently purchased the Amazon Basics 14-Gauge Audio Speaker Wire Cable in the 100-foot length. Let me share my thoughts on this product:
Quality: The cable is made of 99.9% oxygen-free copper, which ensures high-quality, undistorted signals. I noticed a significant improvement in sound clarity compared to my previous wire.
Durability: The insulated exterior jacket is both strong and flexible, making it easy to route the wire around corners or through tight spaces. It feels robust and well-constructed.
Color Coding: The red and black color coding simplifies polarity identification during installation. No more guessing which wire goes where!
Convenience: With 100 feet of cable, I had plenty of length to connect my speakers to the A/V receiver without any issues. It’s convenient for larger rooms or setups.
Price: At $35.90 (only $0.36 per foot), this speaker wire offers excellent value for its quality. Plus, it’s eligible for free returns within 30 days.
In summary, the Amazon Basics 14-Gauge Audio Speaker Wire Cable is a reliable choice for anyone setting up a home theater system or connecting speakers. Whether you’re an audio enthusiast or just want clear sound, this cable won’t disappoint.
Highly recommended!
Comparison with Similar Items:
If you’re looking for an alternative, consider the Monoprice Access Series 14 Gauge AWG CL2 Rated 4 Conductor Speaker Wire/Cable. It’s fire safety rated for in-wall use and comes in a 250-foot length.
Remember, good speaker wire can make a noticeable difference in your audio setup!

Solid Value 14 AWG Cable, but Jacket Design Could Be Improved
Size: 200-Foot, Style: 14-Gauge
This Amazon Basics 14-gauge speaker wire gets the job done at a very competitive price—under $0.15 per foot for the 200-foot spool. I’m using it for my surround sound speakers, and electrically, it performs just fine for that purpose. Whether it’s truly 99.9% oxygen-free copper (OFC) is hard to verify, but for my needs, it works well.
One major downside is the non-round cable jacket design. There are no internal fillers to keep the wire shape consistent, which makes stripping the outer jacket more difficult than it needs to be. Because of the uneven shape, it’s easy to accidentally nick or cut the insulation on the conductors inside while trying to strip it. Including fillers or a more robust outer jacket would make this product significantly better.
On the plus side, the cable has printed numbering along one conductor, which makes it easier to measure and cut lengths accurately—definitely a helpful touch for multi-speaker setups.
In short, this is a cost-effective solution for basic speaker wiring, but the cable construction could be improved to make handling and prep easier. Still, for the price, it’s hard to complain too much.
