The Best Damn Amp Kit Period

  • Thicker Than The Competition!
  • Exceeds CEA Standards for 1/0 Gauge Wire!
  • More Flexible & Easier To Install!
  • Higher Quality Materials!
  • 100% Oxygen-Free Copper



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.



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.

If you are looking for an extremely well engineered and high quality 1/0 gauge multiple amp wiring kit, look no further than the NVX XAPK1D Power Installation Kit. It includes everything you'll need to get your amp(s) powered-up safely and properly.

NVX engineers chose to utilize top-quality materials throughout the kit, including true 100% oxygen-free, silver-tinned copper wire throughout. This full copper wire helps prevent 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 an NVX XMANL04 brass and satin-chrome plated ANL/Mini-ANL Fuse holder with a 300 Amp ANL fuse, protecting your system from costly power surges or grounding issues. Also included are two XDBU4 distribution blocks made from solid brass and satin chrome plated for the best power transfer possible. They are designed with one 1/0 gauge input and four 4/8 gauge outputs for a wide array of power/grounding applications. 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.

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.
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.
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.
1/0 gauge
Power Wire Length
This is the length of the power wire in feet.
20 feet
Power Wire Color
Ground Wire Length
The length of the ground wire in feet.
3 feet
Ground Wire Color
Speaker Wire Included
If speaker wire is included, the value will be "Yes" and if no wire is included, it will read "No".
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.
Fuse Holder
This is the type of fuse holder that is included in the item.
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.
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.
Two with 1/0 gauge input, four 4 gauge outputs
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.
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)

The city of Breaking Bad

Excellent Quality

May 23, 2016

I recently purchased this from Sonic for the install of my two JL Audio amps (Slash 1000/1v1, Slash 500/5) and I was really impressed with the quality. The installer told me it was a really good cable and was what I needed for this install. It is really flexible and easy to work with which is what you want when dealing with heavy 1/0 gauge. I had just enough left over to do a Big three upgrade. I bought this and the NVX 12 gauge speaker wire and RCA cables. I spent a little over $200 for the wiring but you pay extra for quality. It was money well spent. You sound quality is only as good as your weakest link and usually that's the wires used.

Hi. Can I use these two cables from 4AWG as big 3 upgrade, because I do not know what to do with them? If Yes,it's necesarly to put put the fuse from the battery to the alternator? Thanks , sorry for grammar
Gelu P on Feb 6, 2015
Best Answer: You could do, but you are going to need good connectors to insure your electrics don't fail when starting the vehicle, and you should fuse it for sure at the battery end no further away than 18" I personally would try to get a same gauge of cable that had tougher insulting
I'm sure it will be fine you must use a fuse better a fuse Pop than set your car on fire

what is the best amp kit for over 1600 watts? This says up to 1000 watts.. confused new to all of this
A shopper on Jul 25, 2017
Best Answer: First, the description says "over 1000 watts", not "up to". But also, this amp kit is a "Dual Amplifier Wiring Kit" , which means it's meant to wire up two amplifiers to one power source (i.e. battery).
To your question, the "best amp kit" would no doubt be the Kicker 1/0 AWG Amp Kit .


However, we have no problem suggesting the NVX XKIT02, which has all the main items needed to install an amplifier.

What is the temp rating on the 1/0 wire ? I am using the left overs form my amp install for my big 3 upgrade..
Travis S on May 22, 2016
Best Answer: Good question I honestly don't know
But wouldn't harm it to put heat shrink around it and avoid the exhaust system and manifold areas,
use heat shielding where you may need it
Like the stuff you would use on the wall behind a house hold heating radiator ,use cable ties etc to keep it all tidy away from pulleys or moving engine parts etc
It must have to put up with some deal of heat ask NVX too
