Customer Ratings & Reviews

Durable

The wire is so thick for quality sound production and yet so flexible. I didn't do my own install but the installer guy asked me about the kit and seemed to like the ease it offered

Quality

Top quality kit. The power cable is very easy to bend, and the fuse block is well built. My only complaint is the oddball fuse

NVX XKIT42

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.

Real nice

This is a really nice kit has everything you need

Great service again

Another great buy! Chris took care of me again! Every one looking for car audio and your not shopping here your getting robbed!!!! If you don't believe me check for yourself. Just the customer service makes it worth buying anything from here. And any questions you have they are quick to get back to you and help you out.

great product!!!!

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..

Not your average amp kit.

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.

Best wiring overall

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.

Very good wires at a cheap price

Wire if true to gauge, also 100 percent copper very cheap price for the better quality of wires you get plus the hyper flex material makes it very easy to run wires ,overall great wires for price

Love this kit

Great true 4 gauge wire kit. Both power/ground cables are flexible easy to work with, rca calbe is great. This kit comes with everything you need for an amp install. I will be using NVX amp kits for now on future installs.

Excellent quality, very impressed!

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!

Best Amplifier Kit

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!!!!!!!!!!!!!!!

One Of The Better Brands

I really liked this kit for the quality and attention to detail in the manufacturing of this product!

Good bang for the buck

Very nice kit for the money, comparable to kickers flex wire.

great item

this kit is great work perfectly with my AMP and had plenty of wire left over should i ever need it later

Sweet Deal

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 wiring kit for that price

Wiring kit is really great! Delivers good power and isnt made with a cheap plastic isolation but with a nice flexible rubber isolation. Best wiring kit i had so far and i would buy it again if i sell my car because really....this wiring kit makes me one happy customer.

Great kit.

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...

Great Wiring Kit

This kit had everything that i needed for the install. The wire has great flexibility for the installation. Couldn't have asked for anything better. You will not be dissapointed with this kit!

it's a amp kit.

Does as needed. Plenty of wire, plenty of all needed.

Perfection

Exactly what I was hoping for. NVX quality is well above standard. Everything this Amp Kit has came with is just what I wanted, needed and then some. For the price it may seem a bit higher than competitors, but in this world you get what you pay for. From the nylon braid, to the expandable fuse holder (compatible with 1/0 gauge wire) terminal connectors already attached to the Power and ground wire, not only did it save time for me but made the install that much cleaner. Thank you NVX for the superb products you make. I have officially found my new favorite mobile sound company!!

Get ir

Nvx is a great company would recommend them to anyone doing pro setup of ameture. The cord is not a cheap piece of garbage like eBay kits but is actually true size and has great install hardware as well. Don't let the other products fool you people we get what we pay for so choose NVX and have your system slumpin and heads turning.

Excellent materials

Quality of products included in this pack far outweigh the cost. The bundle is the way to go and the power cable is first rate. The fuse holder is perfect and easy to install and the rca patch cable are marked for easy identify after yo have the head unit installed and your in the back of the vehicle and know which channel is which.

Best wiring kit I've ever purchased, would buy again, NVX POWER

All you need for most installs

Comes with everything you need for most installs. Sheilding and core quality is head and shoulders above most top name brands and even cheaper in price.

Amp Install Kit

Not much to say about this. The wire is extremely flexible and its true 4 awg copper wire. The only thing I don't like is the speaker wire is hard to strip if your not using a knife. I got a good deal with a nvx bda750.1 with this wire. I highly recommend that amp if your on a budget.

Great cable

This is the second time using NVX cables and once again it did not disappoint. Nice kit.

Quality product

I used to just use any type of wiring kits cheap knock offs I had an issue with my bass fluctuating and I went ahead and tried Nvx and it solved my issue since then I’ve been using nvx

Great price for what you get!

This kit was exactly what I needed and a great price. Plenty of wire length for my 2016 F150

Good Cable

Worked perfect for me. Plenty of cable is included as well. I have enough to keep over for my next truck. In-line fuse is nice as well.

By Anonymous on February 26, 2019 Verified purchase

High quality

I recommend this amp install kit. High quality solid copper with a heavy 4 gauge power wire. This is the second kit I've purchased and installed. Comes with everything needed for a complete job without buying a bunch of other stuff. Nice price point also...

Does what you need it to

Does what you need it to. Comes with 6 different fuses. Only problem was there’s no mention anywhere on what size drill bit to use for the 1/2” grommet. It’s 5/8”

Great package

This has everything you will need and more. Has a lot of extras built in the kit.

nice kit

first time I used this kit it was easy to hook up and I had plenty of wire

Amazing product!!

I ordered this product and it was shipped and delivered supper quick. A very good price it includes everything even the “butts” for the wires. Would defiantly recommend this product!

Great Amp Kit

I've always been fond of and recommend NVX amp kits, they have great quality components from the wire to the fuse block to the zip ties and included heat shrink tubing.

Good stuff

By Seadooer on January 14, 2016 Verified purchase

Awesome wire.

Purchased this to install a JL audio amp in my 2014 Ford Focus ST. This wire is awesome and I had plenty of extra to be able to put the amp where ever I want. Super great quality, worth every penny. Make sure you buy the correct fuse for your amp though!

NVX XKIT42

It great quality wire and makes installing much easier great product

Awesome

Wire looks a lot better than I thought it would. Really surpassed my expectations.

Everything you need

this amp install kit comes with everything needed to properly power your amp power wire seems to be of good construction and rca cables seem to be pretty descent . the only thing i didn't like was the speaker wire is small for a 1000 watt amp.

NVX XKIT42

this is a really nice wiring package. very pleased and easy to install

True copper count, high quality wires, I will buy another set when I get my next amp

solid

i would buy it again, and probably will next time i need a 4awg install kit

By Kevin on August 18, 2017 Verified purchase

Good kit.

Everything included was quality. Worth buying. Only nuisance was the ground wire was only 3ft. But my audio guy said all kits are like that. It just was too short for newer model 300s.

Worked as advertised

This kit has plenty of product. Install was much easier using this kit.

By Lou on December 31, 2016 Verified purchase

Great wire, all you need

This wire kit has all you need and the wires are not cheaply made

NVX XKIT42

Very good quality wiring and fuse block. The only thing I wish was different is the spade terminals. Wish it also included ring terminals. Still a great value though.

NVX XKIT42

Product was great. Extremely satisfied. Great quality which made for a easy installation.

High Quality Kit, can't go wrong!

If you want a quality 4 gauge amplifier wiring kit, this NVX kit does it all. The term "you get what you pay for" is true for this kit. Spending a little more pays off with 100% copper with an oversized 4 gauge wire, ground, quality RCA cables, and great speaker wire and remote turn on wire. Extremely satisfied and adds to the quality of the amplifier installed in our car.

NVX XKIT42

Ive used this kit for several installs. The quality of the wire is top notch as are the fittings. I definitely will use it again.

By Anonymous on May 28, 2018 Verified purchase

Excellent kit.

I use to use Rockford amp install kits but went with NVX because I liked a few things better about the kit especially price. Easily the best Amp kit Ive ever used. Everything you could need to install an amp is included and the 4 gauge wire is the most flexible wire Ive seen. Very easy to install the kit because of how easy you can bend the wire. I’ll never buy another brand again.

Best RCA in a kit ever!

Most RCA cables in these kits are bottom of the barrel, cheap crap. I work with precision calibration equipment and measured the capacitance of the RCA and both channels with a 1693 RLC digi-bridge (traceable to NIST) and they came out to about 25-26 pF per foot! I bought the standalone X-series RCAs from NVX and these were also 25pF. I'm convinced NVX doesn't sell a single bad cable or accessory.

The kit came with numerous adapters for mounting the cables to power and ground sources and even some quick disconnects. Highly recommend this kit!

By Terrell on August 14, 2017 Verified purchase

True Power

According to past reviews it seems this kit was way more expensive. For the price this kit definitely exceeds every bang for your buck. Never thought shallow mount subs could perform so well but the key to the subs pushing true power also relies on the wiring. Very flexible, thick wiring and neat packaging. Although SE seems like they are pushed to sell this product, it sells itself. All you have to do is take a chance on it. You won't regret it

Quality!!

This amp kit is solid. When the installer saw it he said "oh yeah, you got some good stuff". If you need this get this brand. Great price and great quality. Go with the oxygen free. It's worth the extra 10 bucks or so of you're thinking long term. Having to rewire your amp kit because of degradation is going to cost more so pay the extra 10-30 bucks

As described.

Multiple different fuses. Everything I needed to wire up my amp / sub.

Great kit

Came free with an Audio Control LC-1.800. Have used these kits before, great quality.

This wiring kit is great, I don't have any problems with it, wired it on SKAR RP-1500.1
and it runs my sundown sa 12" really well, unless the amp isn't that good for the sub!

NVX XKIT42

Easy set up, perfect kit for anyone who knows what they are doing.

awesome kit

5/8/16. This kit comes with all the necessaties needed to hook up your amp but what makes this kit stand out from the rest of the competition is the quality of the wire. Nvx has got some of the best wire around. Its a little pricey but if you want quality over quantity, then this wire is what you want. I'm using it to run a hifonics hfi 1000.1D. With a nvx 1 farad cap. It made a very noticeable difference in the bass. Its was a big improvement over my old wire. Overall this is excellent wire if you want the best

Nvx simply has been my go to since my first builds. The gauge over exceeds the standards in todays modern kits. Hands down the best kit ever.

I highly recommend purchasing this kit to whomever is in need of an amp kit.

Kit was easy to install and had more than everything you need for the install. Only thing I didn’t like was the power wire connector was too small to fit on my positive battery terminal. 2007 GMC Sierra classic. Just had to modify the connector and it worked just fine. Other then that, great install kit.

Love this installation kit! Very good quality, everything you need and unlike other kids is ready to connect to your battery terminal stud or other power stud if you have one. No having to put the ends on. Love the extra feature of the wire wrap around the wire for inside the engine bay.

Great kit, just one thing

Huge fan of NVX, the quality of the kit at the price point is very reasonable and overall the install went pretty well, AND it looks great!! However, the heat shrink sleeves have almost no hold, even after using my torch the sleeves kept sliding off of the ends of the sheathing, I ended up using my own heat shrink tubing in some places.
