True 4-Gauge Power/Ground Wire Cable

NVX engineers chose to utilize top-quality materials, including true 100% oxygen free, silver-tinned copper amp power/ground wire for the XW4BL20. This full copper wire helps prevent signal and amperage loss through the entire audio system, allowing your amplifier and components to operate to their fullest. The ultra-durable, EnvyFlex outer jacket makes installation and routing of the cable a breeze.






Flexibility

Flexibility

NVX stranded wire is extremely tolerant of the rough conditions in vehicles and compensates for vibration, heat expansion and flexibility. This flexible but well shielded wire is crucial for getting through all of the nooks and passage ways within the cramped confines of vehicle interiors.


 
Cable Thickness

Cable Thickness

The thickness of the actual wire, not the insulation, is critical when it comes to transferring the extraordinary current of your audio system. With hundreds of strands of wire in one cable you get an increased current flow and a higher amperage carrying capacity with a reduced cable size.


 
Insulation Material

Insulation Material

EnvyFlex insulation hinders electric current from exiting the wire prematurely which prevents electrocution and damage to components within the vehicle. Additionally, the insulation maintains the flexibility of the wire while preventing corrosion and damage in the hostile vehicle environment.


 
Bundled Copper Wires

Bundled Copper Wires

In an attempt to beef up their wires, some manufactures use all aluminum or mix copper and aluminum to give the appearance of a quality cable. NVX wire is 100% oxygen free, silver tinned copper which reduces corrosion, increases current transfer, and won’t discolor the insulation of the wire.


 
Weight

Weight

NVX wire is hefty and strong, but not overly shielded to increase its weight. A quality cable just feels right with a perfect size to weight ratio that leaves it easy to handle but rugged enough to perform its duties.

Power / Ground Cable Specifications

Wire / Cable Type
Wires and cables are made for different uses. This use that the wire or cable is made for.

Please make sure that the wire you are purchasing matches the intended use.

Length
This the how long the item is. When purchasing an item that requires a specific length (such as RCA interconnect cables or speaker wire), please make sure that the length of the item is long enough for your needs.
20 feet
Wire Gauge
The measurement of the diameter of wire. As the gauge number increases the size of the wire decreases. As the wire gauge number decreases, the diameter of the wire increases. For example, an 8 gauge wire is going to be larger than a 16 gauge wire.

When purchasing wire, make sure that you know what size, or gauge of wire is needed.

Blue
Complies to AWG Standards
Since 1857, The AWG (American Wire Gauge) system has been the standard for measuring the diameter of wire. AWG standard is the measure of bare wire to find true gauge. Companies that do not follow AWG Standards include the thickness of the wire jacket which means the actual wire is not "True to Gauge".
Yes
Wire Material
The material that the wire is made of. Copper & aluminum are the most commonly used materials. OFC - Oxygen Free Copper is the ideal choice for wire material. Copper is a superior electrical conductor, & does not expand or contract with heat. CCA - Copper-Clad Aluminum is a suitable choice for lower powered or budget applications. The power transfer is not on par with OFC, but this material offers significant savings.

NVX 4GA.

June 6, 2014

NVX is a fairly new company, and so far what I've seen they make quality products at a fair price. I bought the NVX 4GA. to do a second run of 4 gauge, the size of the NVX was slightly larger than average 4GA and more flexible. and the the strands were larger and denser. I'm running 1000 watts rms and have no heating or shorting issues at 16 feet.

Best wire I have bought

April 28, 2013

I got this because it looked good and it was every thing that was in the pic. This is some good stuff that NVX has made super flex able and easy to cut. I would recommend this wire to people. This is true gauge wire not like some other stuff out there. The only cons were I could not find one that's how good this wire is. I hope that this will help you on getting this wire.

NVX= Quality. End of story

September 6, 2015

I'm currently switching my entire system over to NVX. I've purchased all the wiring, subs, box, and sound deadener and have yet to be unimpressed. Do yourself a favor.....just buy NVX and quit wasting your time and money. I've run kicker for years and MTX (the old stuff when you could easily put double the rms to a sub) and in MY OPINION, NVX comes out on top.

With The Best of 'Em

August 18, 2015

I've been a car audio nerd/enthusiast for literally half my life; I'm 30. I am not nearly as involved in the hobby as I used to be, but I have seen plenty of things over the last 15 years...and there has been no shortage of variations of power wire.

That being said, this NVX wire hangs with the 'Big Boys' or 'The Best of 'Em' at a very reasonable, or the best, price. It is true to it's AWG and is just as flexible as the Kicker wire; which became my standard for comparison years ago.

The picture for the item listing doesn't do justice to how the wire is wound/bundled. It is a honeycomb, 6 outer bundles with one in the center. Since the wires are nicely wound together it takes much less effort to get a tight twist to easily insert into a raw wire input. I'm assuming this contributes to the flexibility of the wire as well as minimizing fraying when you cut it; which is a plus. While on the topic of cutting wire, you NEED to pickup those XScorpion wire cutters...They're nothing short of amazing...Even cutting 0GA effortlessly!

The shielding is wrapped/applied to the wire very tightly, yet is still forgiving enough to cut it and easily (enough) slide off the end to attach a ring terminal or slide into a raw wire input.

Wire accepts solder very well even without applying any additional flux.

If you are curious as I was regarding the silver-tinning of the wire I have some interesting and good news for you. A google search leads to minimal useful/helpful information with people leading you in both directions as to the usefulness/purpose of silver-tinned copper. Well, a friend of mine does construction for a living and had some short lengths of industrial grade 2GA wire in his garage. I was looking at it the other night and to my surprise found it was silver-tinned as well. This tells me it must provide some benefits(At the very least I presume it is for corrosion resistance) if that's what they're laying in the ground and running through buildings to provide them with power. Take this as you will, but I believe it's a good sign.

All in all, you shouldn't hesitate to buy this wire. And most importantly don't be fooled by cheaper wire that has thicker shielding or is copper coated aluminum!

Best wire for the buck. Appears to be the same wire construction, materials and amperage rating of the Kicker and Rockord wire. Silver tinned ofc. Doesn't get any better than that.

The REAL DEAL

July 21, 2016

Yes this wire is the REAL DEAl and with so much cheap copper plated aluminum Chinese trash out there it is both refreshing and a releif to have found this wire.
You don't have to tell me how true gauge your wire is if you build it to be rated for AWG standards.
Premium OFC wire, its not cheap but you get what you pay for in this world.
Great wire that can handle the power without losing your wattage to heat.

Excellent Cable, Great Price

November 29, 2015

I was extremely happy with this cable; it's extremely ductile and easy to work with in the tightest conditions. Add a few drops of liquid dish soap, and the silicone jacket becomes near-frictionless for long/complicated pulls. Build quality is excellent as are the materials.

For the purpose of sleeving, what is the diameter of this 4 AWG wire?
ikenj on Apr 2, 2015
Best Answer: Ok I just went out and measured the wire. The NVX 4 AWG wire measures .390 inch with my Mitutoyo caliper. I am a 25 year + machinist, And I know how to measure. Given that it is a coating around the wire it might vary +- .010 inch or so. You can look at a drill chart or equivalent to get the nearest fraction. I do believe it is quality wire for the price.
