Awesome Wire

This wire kit is of the utmost quality. The wire is actually thicker than 0 gauge! I probably only needed 4 gauge wire for my setup, but this ensures maximum safety and power delivery without putting a strain on any of my components. Excellent item.

Great Wiring kit!!!

This kit has some of the best wire I have used. Its true 0 gauge and really flexible. The fuse block is really well made and easy to swap fuse. Over all I would recommends to other people.

good cable

The cable is thick and heavy! Decent product! What I actually bought was a "package" it came with a RCA cable as well. I was expecting a 300A fuse but got a 150A.

quality product

First thought upon opening this product was the quality the full spec wire is the only way to go really nice fuse block and the ends are already crimped on one end makes it easier to use i have used other products in the past that cost way more money and i dont think they are as nice as nvx its the only way i will go for now on !!!!!!!!!

there GREAAAT!!!!

this wire kit is great very easy to flex . thick and true to gauge wire kit. price is a lil bit higher then the stinger kit but love to product overall

No more dimming headlights

Saw EXO reviewing the kit on YouTube and gave them a try. Very good quality and kit came with everything needed

High Quality Kit

Top of the line amplifier wiring kit. No cutting corners on materials here. Heavy gauge, quality wire. I have it installed with the NVX JAD 1200.1 amplifier and it is the perfect set-up. The only complaint I have is that it doesn't come with RCAs. High quality, true 0 gauge wiring that keeps everything running efficiently and cool!

Super easy install

Great set! Had everything I need and even some extras!

Very Good Product

Ive used numerous high end kits in the past and this kit is just as good as any of them, if not better, at a fraction of the cost. The amount of wire is great especially considering what some companies call 0 gauge, this is true 0 gauge. Add to that the fact that its silver tinned and that makes it an incredible product. Its flexibility is also note worthy, especially as most other brands of 0 gauge is fairly stiff. This is a great product.

Amazing Amp kit

The wire in this kit is incredable. It is copper wire with a silver coating around it. It is the most flexible wire of this size that I have ever seen! I even love the 12 gauge wire that comes for the speakers. This is the best kit I have ever purchased hands down. The cons though are it doesnt come with RCA cables, This did not matter to me as I did not need any anyway.

great product

these rca's are really good and are really long. i have a 90 bronco and i ran them over the door to avoid any signal mixing and i cant complain at all

Great product

This simplifies the installation of multi channel amps while using premium materials

Great true 0 guage

This wiring kit is awesome I put it in a nissan sentra and it is super flexible to make tight bends. Really all around great quality I liked that it came with ring terminals pre crimped onto the kit. This is my first nvx wiring kit and I won't use any other brand now.

NVX Xapk0

It is a good product but not worth the price I kinda wished I bought
Something cheaper that's same quality and comes with more
It didn't come with RCA wire I had to go pay 30$
On top of the 160$ just spent for the kit I think there stuff
Looks cool and does the job but not worth the price

great sound

Highly recommended these for the best signal for the best price

Great amp great value sounds good with 4-5-inch Rockford fosgate speakers+ 1200watt Rockford mono amp. And. 2-12"Rockford. Subs it rocks.

Can't go wrong with Rockford fosgate bought it for my sons car sounds great; and would recommend this product.

Works as advertised.

>I got these to run my mids/high amp. Also got the single version and ran it to my sub amp.

>It is nice having full control over your audio setup.

>I am very impressed with the solid build on and quality on these cables.

>Easy to work with.

>I would definitely buy again. A+

Perfect

They give rich sound. There long, and if you get certain amps you can get this with a discount. I recommend this to anyone who had a 4 channel or 5 channel amp.

NVX > everything!!!

I can find no flaws with any of my NVX products! These RCA's are wonderful too! My 2008 Town & Country is the happiest vehicle ever! RCA's are strong, flexible and visually appealing... even though all of my wires are hidden! Sound quality is GREAT! NVX is the best!

Heavy duty wiring

I bought this to help with my system shorting out and it worked awesome!! I had my first system installed and they used 4 gauge it it didn't work out to well I ordered this nvx product and ran it all myself and it is fantastic I have not had a problem with my system since then! I'm running an nvx vcw 152 and a kenwood 2000 watt amp it hits hard and sounds great thanks to sonic for having this at a greT price and fast delivery

Nothing Fancy but it works well no noise

works very well so far no noise easy to run

Really good

Worked really wonderful as describe. The quality was excellent. The time of delivery was great.

Great product

Inexpensive products built with quality worked better than more expensive brands no engine hum and quality connection.

Twisted pair RCA cable

Really flexible and easy to run RCA cable. No issues with sound quality. RCA ends hold nicely without being too tight.

Great flexible cables

These cables are easy to run and very flexible. No signal issues. No noise, just pure signal. Very happy with them. Easier to run than 2 pairs of cables. Happy with the quality vs price ratio

NVX XIV45

I ordered these RCA's about a month ago and in true Sonic Electronix fashion they arrived within a few days. They replaced 2 pairs that had started shorting out on me. They look and work great very good quality. I will be buying more later on when I do a few more upgrades. Pro's look and work great very good quality very good price. Cons none. I would absolutely recommended to any needing a 4 channel RCA cable.

buy now before this brand becomes huge and price cause its well worth it.

Pure wire with twisted braid. Good connectors great rubber coating n has little flex to it.
Nvx should charge more for all there produces but don't cause they know there stuff is good n it will sell and be known as one of the best brands out there.

Nice RCA cable

Very nice cable! Looks great, feels thick but is also very flexible. Would definitely recommend to anyone who is thinking about upgrading their car’s audio system. RCA cables have an important task.

By Ariel on July 22, 2020 Verified purchase

Top notch!$

Honestly NVX is a great up and coming company! There products work well along with performing flawlessly! These wires have superb sound quality and look amazing as well! Great great great buy! Love them and also got the 2 channels as well,good job NVX

Great value

Works as described best bang for buck in wiring no noticeable noise

Sounds better if not the same than more expensive rca's that i have used..

I've used Stinger , Rockford Fosgate, Monster, KK, Scoshe, and plenty others... the NVX sounds just as good if not better. Not a hint of noise, easy to work and made just as well as the others.. and all for about 1/3rd less $$. No brainer.. Worth it!

Unstoppable quality

Absolutely no reason to buy gamey name brand RCA wires. Low resistance, no noise, and a great jacket. Thanks for the hookup!

By Thomas on May 28, 2020 Verified purchase

Does the job

Works fine. Colors for the plugs could be better. White black blue and gray

By Thomas on April 19, 2018 Verified purchase

Sweet RCA's

These sound great and do their job but they are nice looking & very flexible as well i defiantly recommend these.

Switching to Crutchfield

Like these at first, then they turn out to be loose RCA cables sonic got rid of many products back in the old days. know every day less products or more expensive switching to other stores

One Word: Quality

If you're looking for a wiring kit and haven't bought an NVX kit yet then you should. I'm currently using their 8, 4, and 0 gauge wire in my system and there is one word that can sum it up: Quality. I honestly don't think you can get better wire than this, the 0 gauge in this kit is almost as flexible as their 8 gauge, it's crazy and makes for such an easy time installing it. This kit does only come with a 150 amp fuse and I personally think its a little small but that's not much of a complaint, a 250 or 300 amp can be had for like $5. I definitely recommend this kit, it's worth the extra money over those "cheaper" kits.

By Brad on February 11, 2018 Verified purchase

Great product

Works great, no complaints at all. Very high quality product for not too much dough.

By Derek on March 23, 2017 Verified purchase

Great purchase!!

I was installing a sub in a global ford ranger and this made life easy and had loads of extra cable and they were all high quality as described.
Top notch stuff.

Thanks

Great kit

The ease of us due to the power and ground already being fitted was fantastic. I loved this kit and will definitely being going with NVX again in he future.

By Marcus on January 12, 2021 Verified purchase

Awesome

I would definitely recommend this product or any of the NVX wire kits to and for anybody. Well priced, and just as good as all the more expensive kits out there. Pros true 0 gauge wire, very flexible, bendable true to spec. Even their speaker wire is great and I have to say I can't complain. No cons for this guy.

Flexible 0 gauge

This kit is Awesome. Big flexible 0 gauge with 12 gauge super flex speaker wire and a 0 gauge fuse holder. All Oxygen Free wiring! NVX is doing all my wiring needs from now on.

Great quality

I was hesitant to purchase this kit at first but glad that I did. The quality is top notch and I say this is the best bang for your buck.

Clean, professional grade, high quality, wiring that performs at all levels of competition

By Tim on December 4, 2015 Verified purchase

Pretty dope kit

Thick and flexible wire true to gauge. Everything came in the package as described. The only thing that sucks is if you desire to make your own ground location it doesn't come with a ground bolt. Came with 3 different fuses 150a 200a and 300amp pretty versatile kit would buy again and recommend it. The 12 awg sub wire that came with it was thicker then the "12"awg wire that my shop installed.

By carLOS on August 6, 2020 Verified purchase

Great quality

Very high-quality cables, you get what you pay for. Good stuff.

Best kit for the money.

This is by far the best quality wire kit made. It has everything necessary to do a great install and you will most likely even have extra stuff left over. I have recommended this to multiple friends and they all agree, NVX makes great products.

High Quality Stuff!

This wiring kit is an excellent value. Very high quality. Very flexible for 0 gauge and the protective loom under hood is a perfect finishing touch.

By Eric on November 16, 2017 Verified purchase

Awesome 1/0 wire

I had some cheaper companies 4 gauge power wire. It was powering my 1600 watt rms system. I replaced their 4 gauge (which was actually 6 gauge) with 12' of 1/0 wire. I'm getting 13.75v at the amplifiers after swapping this out and doing the big 3 I was getting 13.3 using cheap 4 gauge.

NVX XAPK0

The only complaint and this is a big one was that the firewall grommet supplied was too small for the wire. I have one night set aside to do my install. I have the whole vehicle torn apart and its after midnight. I was heartbroken when I went to run my power wire and the whole project came to a halt. Then I had to make a trip to buy extra grommets and had to leave my vehicle torn apart until I was able to get back at it. Not to mention not being able to hear my new system that night. Sonic Electronics NEEDS to fix this. The wire was to big for the NVX amp so it is either bigger than it should be or NVX inputs are smaller. Other than this, the quality of the kit is great.

By a on August 3, 2020 Verified purchase

Well worth the money!

I was amazed at how heavy the kit was and the quality is amazing. Definitely worth every penny and more. There were extra things I didn't need and plenty of wire that I didn't need but they give you all the things you'll need. I would only suggest adding the Alan wrench for the fuse block. But all in all, I've already referred this to another person and will tell others!

By Kurtis on May 6, 2020 Verified purchase

Great product

This amp kit is amazing and would recommend this to anyone I know. The wire size is unbelievable and the difference it made to my system is crazy. Who would of thought by switching brands and wire size would make so much of a difference. I seriously couldn’t find a con even if I tried. If u don’t have a NVX amp kit then you don’t know what your missing thanks sonic electronix.

Great deal

Get a whole amp kit for 1/2 the price around town also comes with speaker wire

Excellent

True Spec 1/0 AWG SILVER TINNED OXYGEN FREE COPPER. Will be buying again.

NVX XAPK0

Awesome kit , wire is huge ! Still need to install my power and ground but the speaker wire was more like a 10g . Great quality product

Good amp kit

Just connected this amp kit to 2 12 Rockford P3 subs. Pushed them clean. Wire are good! Not sure why they aren’t copper color even when you cut them... strange -.-

Good item and very easy to wirk with for installation.. Recommend and for the price , can't beat it...

Best value kits

I've purchased several NVX wiring kits and have been pleased with all of them. Hi quality products at a very competitive price. NVX all the way!

By Alex on October 12, 2023 Verified purchase

Great buy

My last few systems that I have put in have been power by NVX wire, amp, subwoofers, and speaker they all work amazing. The wire is easy to work with flexible and cost is great for the quality of wire you receive

By Pedro on June 1, 2023 Verified purchase

As expected

Good wire performed excellent as expected fro previous repeat orders. Thx

Great kit

This is a quality kit. The wires are nice and made my install look good. The crimped ends are solid and the protection shielding and heat shrink are nice too. I would recommend this product.

Great cost and product

Removed #4 AWG that I thought was ok and replace with this 1/0 kit. I had some 1/0 left over from another install into another friends car and the kcmil was way larger on this product than the other. HIS insulation was thicker making the o.d. the same. Wire terminations were solid too!

By Dustin on March 22, 2018 Verified purchase

AMAZING!!!

It doesn't even make sense how much of a difference these wires have made in my system! Draws way more power to my amp, and my subs hit significantly louder than before! Only using NVX wires from now on.

By Calvin on December 14, 2017 Verified purchase

BEST AMP KIT PERIOD!!!!

Bought this to upgrade from my fosgate 4 awg wire because I bought a new nvx jad1200.1 amp and a 15" nvx vcw sub so of course had to keep it the same!!! This wire is just as good as Rockford fosgate, Kicker, jl audio or any other big brand but at a fraction of the price!!! Is silver tinned ofc and every bit of what 0 awg should be you won't have any regrets when u hold this wire it's nice amd heavy and super flexible, and the kit itself comes with everything u need to hook up an amp if your going over 1000rms (except rca wires) everything in the kit is top notch and will last many years it doesn't include your rca cables for your signal but nvx sells them too and there just as good as the rest!!! The terminals are awesome to but I did have to make the hole bigger for the bolts I used but that wasn't a big deal. Bottom line is NVX doesn't skimp on the copper or any other important part in the car audio game there products will compete with any top of the line brand and if u don't believe me try it for yourself I promise you won't be disappointed!!! And if for some reason u don't like it look me up I'll buy it from u lol jk but really u will not be unhappy with this or any other product from NVX!!!! Not much more u can say about wire lol its ofc and it's true 0 gauge wire with a super flexible jacket u can tie knots in but rigid and will hold up I wanna say the strand count is right above 4700 or 4900 somewhere in there for the price u pay its impressive that's for sure!!!

NVX XAPK0

Good product exactly what i needed for my install no problems so far.
Pros. The 0 gauge cable is very flexible and was ready to go out the box
Cons. None

NVX for life

I always go with NVX products, specially their wires, speakers wire, terminals, amps. They sell very good quality equipment for a good price. I have this kit for a 1200rms set up, no problems.

NVX 1/0 AMP KIT

This amp kit is great for the price. Nothing to complain about as usual as the wire are all quality made and very much oversized which is great. I'll be putting this in my 2020 TRD Camry with a new system I'm building in that so I'm excited to see what kind of power it will give my amps!
