Power Up!

Looking for a true 4 gauge amp wiring kit? NVX is proud to introduce the XAPK4 4 Gauge Single Amplifier Wiring Installation Kit. This package includes everything you'll need, including speaker wire, to get your amp powered-up properly and running at it's peak efficiency.

NVX engineers chose to utilize top-quality materials throughout the kit, including true 100% oxygen-free, silver-tinned copper amp power, ground and speaker wire. This full copper wire helps prevent signal and power 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.

The superior quality and materials of NVX also shows in the included accessories. Working in concert with the wire is a NVX XMANL04 solid 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. 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.
Power
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.

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.
No
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)

Great Product

February 19, 2014

This sound deadener is great the best I have ever used. It is very thick and sticks to anything. I used it on my rear speaker deck cover. I didn't know if it would stick do to the that the cover was made of fiberglass. It worked, stuck to the cover like glue. The only down side to the product is like any the black tar like substance if you get it on your hands or fingers have to use paint thinner to remove, other than that the product sticks to just about anything. The price is great too, dynamat for the same about cost about 3 times as much. The NVX is a much superior product than dynamat also not paying to fill chip foose back pocket.

Great Amp Kit

January 20, 2014

I have been buying and installing car audio for about 18 years and out of all those years I have to come across an amp kit like this. This is the best kit I have ever installed. The wire is true to gauge ofc. I installed it in my car without any problems. Very flexible easy to work with. If you want a good amp kit don't buy this one but if you want a great amp kit purchase this one.

Surprisingly "great" kit

January 2, 2014

Because the “NVX” brand is relatively unknown to me (I am sure some have had more experience with the brand and their products) my expectations were low, however, for the price, this is a great kit. Wire is true-gauge, very flexible, high strand count OFC wire. If you’re looking for a 4ga single-amp kit, this is a great option… amazing bang for the buck value. If this is representative of the product NVX is putting out, the rest of their product line deserves a closer look…

Great amp fit for the money.

September 17, 2013

This Amp kit is great I used exclusive NVX for my system this go round and I am VERY pleased with the quality to value ratio. My only complaint is that the AMP power wire could be a bit longer. now I think it is important to point out that I got this kit because the AMP Power wire is longer in this than most other kits 20ft compared to 17ft. But I think in a kit like this they should give you at least 25ft to cut depending on your needs. Other than that everything was perfect the gauge is true not 'mostly' insulation, the wire is strong and the speaker cable is well made. I did not use the included ring terminals or zip ties I used my own heavy duty ones.

Great buy

December 2, 2012

First time buying NVX product, very good overall quality. The wire itself was very flexible and seemed to be true to the gauge listed. It had more than enough to hook up everything I needed. I actually had extra parts. Keep in mind, this particular kit does not include RCA's, I did not need them for my install as I already had some. The only thing I had an issue with was the top of the fuse holder for the fuse box seems to fit a little loosely once the fuse box was bolted in. It has not come off as of yet, but I've only had it installed for a few days. Overall, compared to some of the other big name brands, I can't see why you'd pay more for their product when this one is very high quality at a great price. Thanks Sonic!

Quality of cabling vs other companies and price.
John O on Sep 3, 2014
I chose this amp kit based on positive customer reviews and research about the company. I think NVX is a good company devoted to making quality products. Also, it was the only kit that offered a 20' power cable and I needed that for my car. Most kits come with 16 or 17 feet of power cable which is not enough for most large cars.
