NVX XCW121 + XCA6K + XKIT02 + XAPK0 - Customer Ratings & Reviews

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!

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.

Super easy install

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

Awesome Kit!

Came With Everything described in kit. If Your looking to push that power to your system, This kit will do it! Worth Every Penny!!

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.

fuccin aye

Well worth the money, go hard or go home!!! Only mess with the best

NVX XKIT02

This is a nice wiring kit no doubt about it. Very sturdy and flexible, easy to work with. It is definitely true 1/0 cable and seems to be pushing the Hifonics BRX2000 amp I have with more than enough power. Rca's are also pretty nice and seem to be working as stated (no feedback or humming). I also like the fact that the battery side of the power cable is pre-sleeved and has the ring terminal already installed for you with heat shrinks as well. Same on the ground cable. Over all its a nice kit, might be a little pricey compared to other kits, but you pay for quality. Well worth the money in my opinion.

Nothing but the best!

A little heavy but my stereo system sounds great! Would buy this again!

Fine Wire

Wires seem accurate. They transfer plenty power but I do have to upgrade battery to turn amp up more only running it at .25(1/4) and even then my lights dim front to back.

Good kit

Comes with everything except rca cables, includes some terminals and boots, look for the bundle and save a lot

premiun

Very good quality and fast shipping, i recommended buy nvx products

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

Awesome

I got this kit to wire a boss 2600 watt amp. The wires were huge there was no way I could run it to my amp. The quality was so great that instead of returning it I used it to upgrade my battery cables and my chassis ground. I only wish it came with more ground wire as I need a few more feet to finish my chassis ground upgrade.

By Ace on June 24, 2015 Verified purchase

great kit

nice kit good quality but says in description 300a fuse but only comes with 150a fuse

----

NOTE FROM SONIC ELECTRONIX:
300A Fuse sent to customer due to typo on our behalf. We also updated the description.

Super Value

I've owned wiring kits before but this NVX kit put in great work, it has oxygen free copper that is flexable and put clean power to your amp. You will not be dissapointed this is a good value product.

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

Really good

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

Nvx O- Guage Amp kit

NVX Amp kit is Pure Quality at first I was thinking it was a little pricey
compared to other kits I found online. I went ahead and ordered because it seemed to be best in quality, and sure enough. Awesome kit
I liked it so much I ordered another to rewire my other truck.
Worth every penny and then some!!

By Roysters74 on April 29, 2020 Verified purchase

Great kit at a great price!

This kit looks great! The wire is definitely true gauge, it measures at 16mm for the housing, and just over 12mm for the wire itself. Having the ends pre-terminated and shrunk guarantees a solid connection without having to buy special tools. The power wire is partially covered in braided sleeving which helps protect it in the engine bay. Fuse block is nice and came with a 150 AMP ANL ( not mini ANL as stated in the description) but no complaints here because that's better considering the amount of current traveling through it. Speaker wire is true 12 gauge as well. Overall excellent kit for the money definitely would recommend!

By Mike on October 29, 2015 Verified purchase

Great wire kit!!

This is one of if not the best value wire kits made. All of the NIX wire kits have the best quality wires and terminals. I have recommended this brand to everyone I know.

By Anonymous on March 13, 2019 Verified purchase

Great Kit!

Great kit! Highly recommend. Very high quality and true spec!

By Raul on April 19, 2018 Verified purchase

Best wiring kit!

Probably the best kit I've ever bought. Nice "true to spec" heavy cables but are very flexible and easy to work with. Comes with absolutely everything needed for a clean install. Only negative is the cover for the fuse holder can pop off easily. That is very minor and I would highly recommend this kit especially paired with the NVX JAD 1200.1 amp.

By Justin on May 31, 2016 Verified purchase

Great wire would use for all my set ups

Good insulation rubber is soft and peels back fairly easy def use again

Awesome product!

these wires are simply amazing.. make damn sure you buy quality wire cutters!! i broke two wire cutters trying to cut it. lol

By tom on May 23, 2016 Verified purchase

Great buy

I bought these wire a little skeptical about them at first but after I got them I was relieved there everything I expected.

By Camilo on May 14, 2020 Verified purchase

One of the good wire kits

Great wire kit. Great bang for your buck. A lot of extras definitely make it worth the money.

By FaceDa6 on May 23, 2020 Verified purchase

Top of the line

This is some serious stuff! 100% OFC is worth the extra money.. Excellent quality wire,super flexible for 0gauge. ring terminals already attached with heat shrink and protective loom .beefy speaker wire and decent RCAs..

Excellent kit

Kit included everything needed. The quality is excellent. Couldn’t ask for better for the price

By Brian on October 31, 2020 Verified purchase

Great Kit

So glad i ordered this kit. If you are going to be pushing above 1000 watts this kit is perfect, this was my first NVX purchase and I have since ordered 4 more. NVX doesn't cut corners and all of their products are top quality.

By STICKY G on January 22, 2016 Verified purchase

Great Product

I have to say NVX makes a great product. I would highly recommend trying this product, I've had no problems and its flexibility and high quality are a few of the reasons to purchase this product and see for yourself.

Great buy

Comes with everything you need. Easy to install with no problems. Great easy to bend wire even 0/1 wire flexed easily.

Perfect

Got this bundled in a deal with my NVX XAD14 amp, The wire is ultra flexible and seems over sized, I used NVX brand wire ferrules for a cleaner look and good connection at all points where I would otherwise had a bare wire connection.

I really love the fuse holder, just be sure if you are installing sideways like say on a fender well you mount it with the side screws for the power wire facing where it’s easiest to access. I mounted mine to the fender with liquid nails LN-2000 and two #8 x 1/2 stainless steel screws after double checking it wouldn’t interfere with hood structure or anything else and drilling a pilot hole for the screws.

I really recommend you get the install bay firewall grommets for this size just in case, they are absolute life savers. My best option was to run powerwire though the passenger floorboards firewall and they make me confident that I will have zero water intrusion.

By Frank R. on July 7, 2023 Verified purchase

Seems good quality

Seems good quality and flexible. The reason I gave it 4 stars under features is that it comes with a 12 awg speaker wire. I used 10 awg.

By Kyriakos on February 22, 2023 Verified purchase

The real deal

The amp kit didn't feel cheap & lightweight. True to spec.

By Gerard on March 16, 2022 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 product

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

By Derek on March 23, 2017 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.

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

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.

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.

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.

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.

By Travis on December 1, 2016 Verified purchase

NVX 0/1 gauge kit

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

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.

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

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

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

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 -.-

By Sean on February 27, 2018 Verified purchase

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

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

Quality product as well as a great purchase and overall good and heavy wire

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

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

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.

Best bang for your buck

I did a lot of research prior to buying this kit. I also bought 20 ft extra of NVX 1/0 to do the big 3 upgrade. Considered GP or one of the other well known competition audio businesses but couldn’t pass this up for the price during Black Friday. The quality of the wire is great and even the fuse in the amp kit seems like decent quality. Having no issues sending power to my amp (Kicker CXA1200.1) and get very little gauge dimming on a stock battery and alternator. I know when I upgrade my system to something bigger it’ll handle it no problem too.

By DanGambleGrit on January 6, 2025 Verified purchase

Solid

Very solid core, heavyweight and plenty flexible. It’s oxygen free and comes with everything you need including the heat shrink for the fuse block connections. Only wished it came with a ferrule

By Derrick on December 30, 2024 Verified purchase

Good quality kit. Was thrown off when I went to install because it didn’t come with RCA cables but that’s an oversight issue on my part.
