Power Up With NVX!

NVX is proud to introduce the XKIT42 Complete 2-Channel 4 Gauge Amplifier Installation Kit. This package includes everything you'll need to get your amp powered-up and running properly.

NVX engineers chose to utilize top-quality materials throughout the kit, including true 100% oxygen-free, silver-tinned copper amp power, ground, 2-channel RCA and speaker wire. This full copper wire helps prevent signal and power loss through the entire audio system, allowing your amplifier & components to operate to their fullest. The ultra-durable, EnvyFlex outer jacket makes installation & routing of the cable a breeze.

The superior quality and materials of NVX also shows in the included accessories. Working in concert with the wire is a NVX brass and satin chrome plated ANL/Mini-ANL Fuse holder with a 100 amp Mini-ANL fuse, protecting you from costly power surges or grounding issues. The power wire comes wrapped in 6 feet of durable nylon braided tubing to protect it from heat and chafing in the engine bay. The dual twisted 2-channel RCA audio interconnect cable helps prevent signal loss and interruption. Even simple installation accessories such as the spade connectors are nickel plated for superior long-term durability and signal transfer.

If you're in need of car audio accessories that are built to perform and last, look no further than NVX.


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.

Amplifier Kit Specifications

Amp Kit Type
Amplifier installation kit come in two different types: Power or Complete. Power Amp kits are designed to only provide power to the amplifier. Complete kits will provide power and signal to the amplifier. Many of the complete kits will also include speaker wire to connect the amplifier to the subwoofer.
Complete
Number of Amplifiers Supported
This is the number of amplifiers that the amplifier kit can support. If you are are going to be powering more than one amplifier, make sure that the installation kit will support them.
1
Power/Ground Wire Size
The power/ground gauge numbers represents the main wire size of the amplifier kit.

Definitions are as follows:

Gauge (wire) - The diameter of a wire. The higher the number, the thinner the wire. Example: 4 gauge wire has more strands than 10 gauge wire.

AWG (American Wire Gauge) - A standard of the dimensional characteristics of wire used to conduct electrical current or signals. AWG is identical to the Brown and Sharpe (B & S) wire gauge.
4 gauge
Power Wire Length
This is the length of the power wire in feet.
20 feet
Power Wire Color
Blue
Ground Wire Length
The length of the ground wire in feet.
3 feet
Ground Wire Color
Gray
Speaker Wire Included
If speaker wire is included, the value will be "Yes" and if no wire is included, it will read "No".
Yes
Speaker Wire Length
This is the length of speaker wire that is included with the item.
40 feet
Remote Wire Length
This is the length of the remote wire that is included with the item.
20 feet
Interconnect (RCA) Signal Cables Included
Interconnect cables are required for amplifiers which are installed to the "RCA preamp low-level outputs" of a car stereo receiver. If your amplifier has high-level / speaker level inputs, then you do not need to purchase interconnects; however, interconnects offer a much higher quality sound when compared to speaker level inputs.
2 Channel
Fuse Holder
This is the type of fuse holder that is included in the item.
ANL/Mini-ANL
Fuse Size
This is the size of the fuse that is compatible with the fuse holder. If the fuse needs to be replaced, be sure to replace it with the same size.
100A
Distribution Block Included
This means that the kit includes a distribution block in the package. This will assist in the installation of the amplifier kit or any situation where a distribution block is required.
No
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". For the best performance from your amplifier wiring kit, make sure that the cable complies to the AWG standard.
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.
OFC (Oxygen-Free Copper)

Not your average amp kit.

July 8, 2014

If you're picking up a bad*ss amp, why wouldn't you pick up a PROPER wiring kit ?! I've previously used NVX Power/Ground wire for a BIG 3 Upgrade install, and was blown away by the Quality of the wire. High Strand, True To Spec, Super Flexible, Very Durable, and Conducts Very Well. Same can be said for the Speaker Wire and RCAs. I wish NVX made a kit with their higher end RCA cables, but the ones with this kit definitely get the job done. The fact that the Power/Ground come Crimped and Shrink Wrapped really save on install time, and the flex wrap on the Power Wire makes the install look Very professional. I ended up using the other goodies (ties and connectors) for various other things, but its pretty cool that it comes with the kit.

January 9, 2014

This is the perfect kit for anything around 1000 watts RMS. I have it hooked to a NVX JAD1200.1, and it is perfect. I literally have nothing bad to say about this kit. Every wire is true to gauge and it comes with plenty of wire, even 40ft of speaker wire! The RCA works great and the wires are strong and flexible. It'd be nice if it was a little cheaper, but it's definitely worth it. NVX makes some of the best, high quality wires and instillation equipment.

Sweet Deal

September 24, 2013

When i purchased my amplifier they gave me a butt load off the purchase price of this wiring pack. Pro's: good quality wire very flexible and easy to work with. Con's: Needs more wire Connectors/Terminals with kit ( that are the right size) Ex: 4 gage wire doesn't usually fit into a 6 guage wire terminal/connector.

Best Amplifier Kit

September 20, 2013

I take my chance when I ordered this kit. I almost spend over $100 on brand name kit. I'm glad I did bought this kit. Don't let this brand scared you. When I opened the package and saw the power cable, I know I made the right choice. The power cable is a true 4 gauge. The speaker cable ,you have enough to run both right and left from front door to the trunk and still have some left. RCA cable may look cheap but so far the signal from my head unit to the amplifier is excellent without any distortion. I love everything on this kit. Buy them!!!!!!!!!!!!!!!

this has to be the best connection kit I have ever used.. everything was flawlessly constructed and everything you need is in the kit, remember you get what you pay for... I am using this in a small suv that has no carpet but herculiner throughout and I need pure copper for corrosion resistance.. could be cheaper I guess..

Best wiring overall

June 2, 2013

when i received this and opened it up i was amazed when i saw how a 4ga. wire could look so much like 0ga. and bend so easily. the speaker wire is so thick that you would not believe that it is speaker wire. the wires also make your music sound so much clearer than any other wiring can. all the components are the best in quality.

Great kit.

March 3, 2013

Bought this kit to run 1000 rms, some high grade power wire, very flexible, the terminations are perfect, came with lots of speaker wire... only bad thing I can say about this it the interconnect RCA cable came damaged... and the plugs on it feel really cheap, the insulation by one of the plugs was broken, just the outer jacket the inner insulation was fine, but it broke in an area where there would be high tension, right against the connector. all in all great kit for just the wires appears to be true to set and ofc, fuse holder was nice as well, just RCA was junk...

Excellent quality, very impressed!

February 18, 2013

At first, I was a little skeptical of NVX products, but I must say this kit feels very solid. The wire gauge is true to size and actually bigger when compared to my Stinger brand wire I've previously used. The wire is extremely flexible as well, making installation in tight places a breeze. You get everything needed to install a single amp in this kit. Don't let the name scare you away, give it a try!
