    • Not true 4 guage
Size: 4 Gauge Color: Red 20 Feet
Out of the packackge this wire was really nice except when I went to use it for an audio install, I realized it's not true 4 gauge. It's somewhere in between 4 and 8 guage. All of my 4 guage connectors are way to big to fit

    • Found a good large gauge wire supplier on amazon.
Size: 1/0 Gauge Color: 5 ft Black + 5 ft Red
The good: Cable is copper, not the crappy copper clad aluminum being sold all over amazon. It's also true awg. Not international wire gauge. Quite flexible. The bad: Upon opening the package, the smell could be described as rotting butyl rubber (smells similar to vomit). However, this is not unexpected, and 24 hours later after airing out it smells like regular ol' edpm rubber. No big deal. ... show more

    • Don't Spend More Money on "Car Audio" Power Cables
Size: 4 Gauge Color: Red 20 Feet
Super happy I discovered welding cable/wire for car audio applications. Welding cable/wire is basically the exact same thing & for a much better price-point. The equivalent OFC "car audio" cable would cost between $10-$15 more & that's for the cheaper brands... $40-$50 more if it says "Rockford Fosgate" on it... So yeah, this is a great deal as far as I'm concerned. The cable is heavy & feels like it's full of lead - yet is very flexible & easy to work with. I upgraded my amplifier power cable from a 4 awg CCA to this OFC wire & could hear a difference right away. The sound is "cleaner" for a lack of a better term. Much more full & rich bass now - with everything else being the same. Now that I know the difference it makes, I'm upgrading ALL my car audio cables to OFC & will never look back (unless I'm broke lol). ... show more

Insulation is nice, it has an interesting smell. Overall cable diameter is a bit smaller than the one that i usually order... the copper does look like a higher grade though...i will be using this for my cars sound system, hopefully is can handle the abuse...

    • Excellent Cable!
Size: 2 Gauge Color: 40 ft Red
I needed to upgrade my old 4 awg cable in my cars to support a bigger amplifier so I researched and found some nice OFC cable here. I got 25ft of the 4 awg and 50ft the 2 awg here and all I can say is wow.... I don't even think my old 4 gauge wire was even 8 awg... closer to my OFC 10 awg speaker wire I bought! So yeah, this cable is very easy to work with, the outer casing is kind of rubbery and cuts really nice with a sharp blade. Very impressed with the quality and WEIGHT of this cable. I now know what real cable is vs. cheap "Amp Kit" cables. :) You won't be disappointed! I actually had to use a reducer on my 4 awg cable to my Rockford amp that is supped to take 4 awg cable! ... show more

    • Finally a good wire!
Size: 4 Gauge Color: 15 ft Red
This stuff is flexible true to its rating and pure copper. Finding a true copper wire is tough. I am using it on boats with smaller engines. The bigger boats will need a bigger wire but for 200hp outboard and V6 inboard outboard it works great. Now I only have to run 6 ft. Or so . I would increase size with lo ger runs. I will buy this again. Great price too. ... show more

    • A PROFESSIONAL AND HONEST REVIEW
Size: 1/0 Gauge Color: 20 ft Black
This cable is absolutely perfect the gauge thickness is true to its size it has great flexibility being a welding power cable and that's the one thing people need to know about what to run for your power cord in your car audio the only difference between running a welding cable and a car audio power cable is that the wires are thinner the strands are thinner in the power cable for the car audio specifically and the welding cord has sticker strands making it not as flexible as the other cable but it's flexibility overall is amazing because when you're running power cable you want you're trying to run it from point a to point b and it's mostly a straight shot from your battery to your amp with very little bends and turns so flexibility should not be such a huge issue unless you're doing a full-blown super custom car audio. the power cord is perfect though I would recommend this to anybody that's running a higher-end a lot of power car audio system ... show more
