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.

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 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! Highly recommend. Very high quality and true spec!

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.

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

Awesome product!

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.

Works but ...

At low volume it sounds as if the subs turned off. Sq is fine but a horrible turn off pop on the subs. Gains have to be turned way past where any amp I had were. You also have to have the bass boost turned up just to get any low end out of the subs at low volume.
Controls on the ends are fine and work as intended.
Comes with the bass knob for the front . Maybe I got a bad one.. Expected more than what I have out of this company. Feels nice and heavy solid construction .

Excellent kit

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

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.

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.

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.

Nothing short of Epic

I admit that i was a bit hesitant to pick this guy up. I could get the same power from cheaper amplifiers, but MTX has been around for years and their products have always been in the SPL scene, so I went with my gut on this on. NO REGRETS!! Right out of the box, the amplifier is clearly build right, hefty, and with high quality components. Beyond that, the aesthetics are nothing special, But I think that speaks volumes! Why waste money on putting a skull with pretty lights on the chassis, and not put that towards developing a proper amplifier. Thats what we got here.

I used proper 0 Gauge OFC wiring to make sure the amp gets the power it needs, hooked up to an XS Power battery, and an AudioControl Epicenter. For having a cheesy name like "Thunder" , you really do get that.

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.

Premium OFC Wire

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.

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!
