GEARit Black Red 0 Gauge Wire 25 ft Set, 1/0 Gauge Wire 25 ft CCA Battery Cable, 0 Gauge Power Ground Wire for Car Audio Amp, RV

For the price, this is great stuff but there are a few things you need to understand BEFORE you buy it so you are not disappointed. The negative reviews are not wrong in most cases and there are some caveats: 1. This is measured in Gauge (usually refers to metric size), not AWG (refers to current carrying capacity) and should be called out in aught if it were truly AWG. Gauge is a faux measurement IMHO. The "standard" is so loose and so not really a standard that understanding that right away is important. AWG (American Wire Gauge) is a strict standard and you know exactly what you are getting. Go pay twice this price and you'll get true AWG measurements. Don't want to pay twice the price? Then you're going to compromise. 2. The individual strands are brittle as mentioned but that doesn't matter. If you're terminating correctly, it makes no difference what so ever. Voltage drop, heating because of amperage or anything like that does not matter if you lose a strand or two. As a cross section of the wire it is just not enough to make a difference. 3. Yes the wire is on the stiffer side, that's a good point made by folks here. It's not bad actually, but figure your bends are going to be the size of a coffee can and maybe not quite as tight as the side of a coke can because it's stiff. Bottom line question: Is this 1/0 AWG (gauge?) Absolutely not. In AWG this would be just about 1 AWG on the thin side. It comes out at about 7.28MM which is basically thin 1 AWG (there is some margin of error in my measurements I'm sure). This is probably 1/0 gauge when you can measure "gauge" any way you freakin' want to. For this price, at this size of wire, you aren't going to do much better. Think ahead. This is a great buy for what you get, just get passed the marketing. I could not find wire this thick at this price on Amazon period and this was the best price by a couple bucks. Buy appropriately. I hope this helped!

This 0 gauge ground wire is fantastic. I was extremely pleased with the flexibility and pliability of it. I used it to run a battery cutoff switch in a van with a 5.4 liter V8. I was installing the switch about 7 feet away from the battery so I needed something that would carry as much power as possible with as little resistance as possible. The quality seems to be top notch. I definitely recommend this product.

Arrived on time and in perfect condition with no issues

Worked perfectly Was used for battery relocation. I don't have a starting issue anymore.

Wires are pretty good. They look good if you're running exposed cables. They're a bit transparent. Plenty of wire strands. Not that flexible but enough to run around corners. Strand do fray as you work with them, but workable. For the price a good buy.

Perfect wire. Used for battery cable on my 7.3l powerstroke. New ground cable and new power cable all the way from starter and up to both batteries. Used 4ga from alternator to batteries. Awesome cable for a good low price. Definitely recommend

Heavy duty and surprising flexible. Very easy to work with.

Haven't had time to install this yet, but I have crimped a 1/0 connector onto the cable for a test. Quality and appearance are top notch and cable crimped really well without strands breaking or fraying.

Just as described, they do their job very well and work perfectly for my car.

I am using these as stickwelder leads amd they are great so far. Outer jacket seems tough too.

Year round temperature where I live id -40 to +40 through out the year, A good cold weather cord can be used year round outdoors or indoors

Cable is flexible enough to tuck under trim and carpet in the car. Powers my subwoofer enough to dim all the lights on the car. Only gripe is that you have to be very careful when stripping the wire as it is very easy to cut individual strands and lose some wire. Even stripping carefully with a somewhat dull knife manages to cut through the cable.
