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 XW4GR20. 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.

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.

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.

Gray
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".

This is the good stuff.

April 25, 2013

This review is going to sound similar to my review of the 14ga wire, but that's because they're both easily and obviously superior to the cheap stuff. I wasn't sure I wanted to spend this much money but without doubt, it's well worth it. This wire (and especially the 14ga speaker wire) is so much more flexible than you'd expect it to be, given the gauge. Impressive stuff. I'm a believer now, and will definitely buy this again when I do my own car next.

How much current can you run through this cable?
Sparky on Dec 20, 2014
Best Answer: 80 amps (constant) is the max through true 4AWG cable. 80A @ 12V is 960W of input power, an efficient amplifier (Class D) should be good until about 600-700W RMS

Any amplifier with a recommended fuse of 100 amps should be fine on short runs of 4AWG. You should use an 80 amp fuse on 4AWG cable even if the amplifier says to use higher. It should be fine as most manufacturers ask for a bigger fuse/cable than usually needed. If the amplifier does blow the fuse almost immediately you'll have to use a bigger cable, if it does it only occasionally you can try shortening the run to make it work. If your amplifier recommends a fuse larger than 100 amps then you should use a larger wire.

Using a smaller fuse than the amplifier manufacturer recommends won't harm the amp, it will just blow the fuse (and protect the wire and your car). If you use a larger fuse then the wire supports you risk catching your car on fire.

Hope that helps!
