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

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!!

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.

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.

Nothing but the best!

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

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

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.

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.

beast

great amp i have it pushing 1 xfl 15 and its a beautiful combo.

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!!

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!

great product at an even better price

Easy to tune and makes every bit of power they claim it does. I live in Florida and never had a problem with overheating. Overall it's a good clean sounding reliable amp

Best amp for the price

Best amp so far... Pushing 2 12's JL W7 and this amp never gets hot or cut off and I can play it for hours full blast.. Had it over 2 years now and no problems. Going to buy another one in a few weeks so my 12's can have there own amp..

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.

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

Super Great...

I would so defenetly recommend this item. This am is a great just enough power.

By Juan on June 8, 2015 Verified purchase

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

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

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..

One of the good wire kits

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

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 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 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.

Hifonics BRX2016.1

I bought this hifonics amp and I usually have some problems with it going into protection mode when I turned the volume quite a ways up I already sent one of these back for that same reason for repairs high powered amp not so much quality I would recommend a good friend for some more quality

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

Best Addition to my System!!!

Went from 600 watts on my jl audio w6 and blew this baby up the very next day after installing this amp it's seriously no joke packs a lot of power I'm currently powering a 15" L7 and its beating it to death great amp needs a lot of power to back it up can't wait for my Sundown X12 at 1ohm I'll be shaking Windows with them lows soon.

By ORALE on February 21, 2016 Verified purchase

Great amp

I would recommend this product,
It has lifted my sounds to a different
Level , very clean and low
I would buy it againg

Great bang for the buck

Had one of these burn up right out of the box, sonic sent me a replacement really fast. This one has been performing as advertised. It's pushing my 2 addictive audio v3 15's real nice. Give it good electrical and keep it cool & you should get years of service. I have a brz 1700 also & this is noticeably louder than that amp. I recommend this product for good value on a low budget. Sonic is a great place to shop.

Top Shelf

The best amp I've ever purchased! Works very well with my system. I plan to buy another for the other car!

Outstanding Amp

I bought this amp for 2 kicker L7 12’s a couple years ago. I bought two more L7’s & planned to upgrade my amp but this 2000 watt Brutus pushes all 4 L7’s with ease!

By andrew on October 19, 2022 Verified purchase

Amp wiring kit

Just as good as some of the big name brands. I’ve had it for a few years and it’s holding up very well. I’ll buy it again. HEAVY DUTY.

By jaimie on March 7, 2024 Verified purchase

Not what I was hoping for

I had this amp installed by a shop to run 2 twelve inch Alpine type R subs. It just isn't loud. I definitely don't get power from the gods. Very disappointed. I got more power out of a Rockford prime 750 amp in my last car. I think the amp might be a dud. Going to ask if I can return

WOW!!

I was blown away by what this amp can do. I have been running it hard since I hooked it up and has not once over heated. The lights on it is a nice touch that makes it look even better. If you are looking for power and a good price this is definitely a must buy!

Awesome amp

Great amp. Pushed my two kicker L5s solos nicely. Highly Recommend this amp

This amp rocks

I have this amp pushing 2 12" Massive Audio SUMMOXLs wired down to 1 ohm and they push the hell out of my subs. Make sure you are using a beefy amp wiring kit because this thing needs some juice. I paired mine with a 4 farad cap.

Legit

Used this amp to power my DC level 4 XL. It gives it as much power as it needs. Setup was a breeze and at max output it only gets about 105 degrees.

It also accepts 2/0 guage power and ground cables without needing to reduce them, which is awesome.

Can't think of anything negative to say about the product. It looks nice and seems to have the power it says it does

Good power output!

Not my first time running a Hifonics Brutus amp I've owned some in the past and i like how the screw down is not plastic anymore so thank you on that note the amp is great.

By Matt on December 14, 2015 Verified purchase

Great value for awesome product!

The hifonics brx2016.1d is an amazing addition to go with 2 kicker cvx's very powerful and for a great price!

Best Hifonics Amp you can get for the money

I got one and slammed my 2 12s for about a week. It got me pulled over with a warning for an Illinois Amplified audio system code violation. I decided to buy one more and strap them together. A true 4k on lithium and 2 regular batteries with a custom box: digital excellence and SPL all at the same time ?????????? 17 hyundai accent base. It’s way better with 2 of them strapped kuz I’m not clipping anymore as it’s all great power kuz them subs i got are strong and underrated

Great choice

Hard to beat in this range of price... Quite happy with it...

Best BANG for the buck

So I haven't installed this amp yet but lol I already have one in my car. I picked up a second one to strap them together and double the power. If you're looking for a great amp that doesn't have a huge footprint and does rated rms power. Than this amp is for you. Not to mention a great reliable company to buy from.

Premium OFC Wire

NVX makes some of the highest quality wire on the market today. I'm a lifetime customer.

Great product very flexible and very good wiring kit

By Eustace on March 23, 2025 Verified purchase

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.

Perfect wiring harness as everything I needed good quality better than expected

High quality wiring kit!

I received this kit for free, it was a promotion with the purchase of an Audiocontrol LC-5.1300 amplifier. It is my first time dealing with NVX power wire. The kit is of very high quality, from the power and speaker wiring itself, to the pre-installed nylon mesh, power connections, and the fuse holder. This kit makes wiring easy and straight forward. It’s easy to see that there was some good effort placed on the placement of all the pieces along the wire run. Another positive is that the wire fits easily into 0-gauge connections. In the past, it could be very frustrating dealing with wire that was bigger than spec. I get the whole “you’re getting more”, but I’d rather have a wire that meets the spec or maybe a little over, but not so much that it takes away from easily fitting into the connections. From this point on, I’m sold on NVX power wire. I will be looking at them for sure for my future builds.

Side note. I did not use the RCA’s, so I can’t comment on them, but seeing the quality of the kit itself, I wouldn’t be worried about using them.

Amazing Amp Kit!

This OFC 0 gauge kit was used in my dad’s Buick wagon for his 4500 watt amp and it smacks with his 4 10” NVX v3 subs. Even he tells me he’s never seen wire so perfectly priced without hurting the bank!
