NVX 1200W Mono Amp with kit and Subwoofer in a box (Sealed) - 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

Real nice

This is a really nice kit has everything you need

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.

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..

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.

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.

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!

great item

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

Good bang for the buck

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

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.

NVX VSW124V2

Bought this to replace a pioneer dvc and was talked into this NVX by Keith. It is just as sensitive despite pioneer claim,their ratings are bogus at 96db as it is an in car rating not free air. This sub out plays the pioneer tsw3004d4,and plays lower with the same power. It has magnets 40mm thick compared to pioneers 35mm,despite only specking at 12 mm,its more like 16mm. Nice job under rating xmax and rms power! I am using a Sony 600w rms on this and its a good match.

NVX V-series

Got this sub, to replace a N-Series 12" sub. I wanted just a little more. This sub is exactly that, just a bit more then the N-Series. The specs match up with my JAD900.5 amp perfect. Nice deep bass. Noticeably more output/bass then the N-series it replaced, seems to also play lower notes, could be a better match to my box though. The V-Series does not disappoint, if you have It in your budget you will not regret stepping up to this one. ALL NVX products I have used have been exceptional, they are now my first choice when car audio shopping.

By Brandon on March 13, 2016 Verified purchase

Awesome Sub

Bought 2 and they play deep bass, with an accurate strong bassline.
Was skeptical because never heard of NVX but definitely happy and impressed with product!

By Tom on August 19, 2017 Verified purchase

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 SQ sub, definitely not a plain midgrade woofer...

Wow... Received mine today, immediately installed it, and dialed the amp in (JAD900.5). Running this beauty solo in a sealed enclosure in a Chevy Avalanche, and it handles 80hz-down no problem (No i haven't pushed it hard yet, i know it's still early). I've got crappy door speakers for now, upgrades in route, and it really brings the music to life. Can't wait to hear it with my new components. A little more power and a perfectly tuned box, i bet this thing is a beast. Simple yet really nice design; nice strong push terminals; heavy magnet. No rating for durability because i've only had it for a few hours. Great for bass you hear and feel.

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!!

NVX Rock Solid

After replacing two Fosgate Prime 12" subs with two NVX 12" subs. I have been trying to chase down A few more screws falling off my door's,it's a new truck don't figure.
Sometimes stuff just works right. NVX ALL THE WAY BABY

Amazing sound!!

I bought 4 of these subs for my 2019 Charger. I've waited a couple of months before posting this review so I could thoroughly break in and test them. The sound quality on these subs is absolutely amazing for the price. They perform equally to some of the other subs that cost quite a bit more, and the quality of the construction is actually better than that of some of the more expensive subs. They hit HARD!! Pair them with a quality box built to the sub's space requirements, pair them with a good amp and enjoy the thump!! I will definitely buy more of these NVX subs in the future.

By Christopher on September 22, 2021 Verified purchase

Just buy 12 right now!

These subs are amazing. For a lower endish sub they slam! They can take power and dual 4ohm coils... so with 2 you have a final impedance of 1 ohm. Which was perfect for my current set up. I am extremely pleased and if you are in the market for quality 12s but dont wanna break the bank.. these are deffinately a very good option. Props to nvx for an awesome product.

Hangs with the more expensive subs

Put it in a good accoustics 1.8 cubic foot ported box for 2012 Quad Cab Ram & driving it with a Rockford prime 500x1 @ 2 ohm. Broke it in slow over 2 weeks & sounds great, gets loud & as low as the box will allow. Might get the 2 12 box & double up on the power just for fun. No complaints & would buy again.

Solid choice

I bought this sub to replace the nsw122v2 I had in a sealed 1.35 cuft box. Ran it off of an alpine mrv-m500 at 300rms (checked with meter). I went with this one because of its specs, gets pretty deep and decently flat curve down to roughly 46 hz. I have it running at 500rms (same amp just 2ohm, again measured this), and I'm thoroughly impressed with this $100 sub. Deep, tight, responsive. I've learned to really enjoy Nvx subs. The base line isn't bad, but these are really worth the extra little bit. Just for reference, I listen to mostly rock/pop and once in awhile rap. Does fantastic in its entire range.

By Keith on July 17, 2019 Verified purchase

bang for the buck

i got these subs as a package deal built for my 2015 silverado crew cab. this is the best sound at half the price i could find anywhere. they sound so good the audio shop i had do the install has called to become a distributor. one of the subs showed up damaged and sonic shipped a new one right out.

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.

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.

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.

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

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.

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.

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!

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...

NVX XKIT42

It great quality wire and makes installing much easier great product

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.

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.

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

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

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”

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.

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!

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

Great product

I like the looks and the flexibility of it. It’s a good product for the money

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

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.

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

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

Great subs. I have them on a 1200 watt hifonics and the quality is amazing. If you want a lot of bass but clean bass at the same time. Nvx is what you need.

Very high quality

I purchased this box for a pair of Kicker Solo Classics. The box itself is very well constructed, solid and well sealed. I did further seal it with silicone for peace of mind, including the terminal cups. I used 1/2 lb per chamber of polyfill and mounted the subs. After initial break-in, I can attest that the SQ of this setup is definitely top-tier, one of the best I've ever heard, which is what I was seeking. I have no doubts this box will outlast every other component of my system.

Great sound

I had a dc audio m3 8inch sub but wanted a little more space so i went with the nvx vsw 12 dual 4 in a sealed box. Took a little time to break in but when it did my punch 500 felt like it was not enough power. I went out and got a down4sound jp3 and this little low level sub is starting to be impressive. I had my dc audio was in a ported prefab. I decided this will be my winter sub while i look for more cone area or a better tuned box but who knows. I highly recommend this sub in a sealed box so far.

First time buying this audio brand. I have bought the rca and wiring from NVX. Loved it. These speakers I bought beat!!! It’s amazing how hard they hit in a potted box!!! Man!!!! I recommend this to anybody!!!! Shipping always amazing!!!

Great Pound for Pound

These 12's pound, it feels like I have Thor trapped in my trunk. I bought them to replace a pair of Rockford Fosgate P2D4 12's and in a sealed sound ordinance box with an NVX 104, 1500-watt mono block amp wired @ 1ohm, and they are more than comparable. In fact, if you take into account the value factor, these top the P2D4-12 hands down. Robust, well built, all the features of my previous Rockford Fosgate's, but at fraction of the cost. The quality was way more than I expected and very durable. I say that because for the first few days of installation I had the gains turned up way too high and I thought I had blown my new subs, but after I shut everything down and recalibrated, I was back and running, no sweat.

By Armando on August 3, 2022 Verified purchase

They Work ok so far

I have 2 of them in a bandpass box, With a Rockville Rxd-t2. I have each one on its own channel wired at 2 ohms. They are loud but could be louder. lol At this point I'm just not wanting to blow them. I can Say that they hold the Rms that they say and don't distort at all. Best deal from sonic deals.

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 sounding sub

Have these subs in a sealed box for a truck. Added some polyfill they sound really good. I'm not running them hard yet and they still sounds great. Thinking about putting them in a ported box after break in now I think I'll keep them in sealed box a bit longer since I like the sound they put out.They play clean and can hit low and that's coming from a sealed truck box with .98cu ft air space.
Love ordering from Sonic Electronix their shipping is quick and fast.

OOPS

This was advertised to fit the Rockford Fosgate P2D2-12 pair I bought. The speakers did not fit in the box together. Good product but did not work out as I wanted.

Awesom subs

I bought these as a package deal with a box that fits under the seat of my 2015 Silverado crew cab. It sounds amazing for the tight space they are in and I haven't even turned the gains up on the amp as I'm still breaking them in. One of the subs was damaged when I received it and they sent me a new one immediately. I am very impressed and would recommend to anyone looking for a great sub at a great price.

Great for the value

When it comes to premade box's Atrend is hand's down one of the best in the market. Also with Sonic's price you can go wrong.

Best value amp kit

When it comes to install kits NVX is hard to beat. High quality OFC wiring and looks good too, no cheap materials like some other brands. Would buy again, no doubt.

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.

Quality wire as usual

True 4 gauge as expected, my go to brand for power cables.

By Kevin on September 14, 2025 Verified purchase

everything works great

4AWG as advertised, plenty of cord length and the cable is very flexible.

Very high quality

Came with everything I needed, the quality is really nice on these wires and cables. Worked great for my setup

This thing slams for the price

First time using nvx and I am completely shocked on how responsive this subwoofer is. I have this hooked up to an alpine amp running 500w RMS to the subwoofer at 2ohms. Still breaking it in but this thing hits like a truck.

Never go wrong with NVX!

Some of the best wiring kits you can get out there especially with it being OFC! I have it running a 4channel and mono block amp and it’s delivered plenty of power to both!

Great enclosure for the money!

This box is seriously best bang for your buck! I have 2 brand new Illusion Audio 12's and this enclosure fit the specs perfectly!
Well built and no leaks that I could find. Which was a concern to me because the black sealant used didn't have total coverage in both chambers. Easy fix regardless, but wasn't needed luckily.

Love how the rear has an angle to scoot right up to your rear seats. This is great if you have an SUV or hatchback. And the design is nice and compact. I could still fit 3 large cases of water in the back of my 4runner with this box back there.
