Customer Ratings & Reviews

Good

This wire is very flexible and fit nicely in my 2000 nissan maxima. ring terminals were a little fussy, but that was operator error. very nice 150 amp fuse. Lots of wire crammed into it. Very inexpensive for the quality. I would recommend this to anyone looking for an upgrade.

Great

It is what it says it is.. no problems with install.

a great kit for the price

these are great for the money and would definitely buy again

Decent Amp Kit

I am a professional installer first of and my father is an electrician. Following the AWG- American Wire Gauge standards this is not 1/0 wire it's closer to 2AWG, please understand that true 1/0AWG copper wire will cost around $5-8 a foot.

That being said for the price it is an amazing kit but should be marketed as 2AWG.

When compare to Kicker and Memphis true to spec 1/0AWG wire there is a major difference in size and weigh over all. 5 feet of Memphis 1/0 Wire weigh the same as 17 feet of Belva 1/0AWG.

Great Wire

It's the size it says it is, and powers my 1400 watt system with no problems. For the price and ease of install, I couldn't be happier!

top quality

I got this kit on a deal with a amplifier I purchased thought it looked good turned out to be one of the best amp kits I have ever owned would of paid full price for it

Great deal

I got this kit because I got a deal on it with my amp...great starting kit...didn't have any problem with it when I installed it...The ground cable was to short for me but that is due to my custom box..All in all good 1/0 Guage kit

good product

Good product, they give you plenty of length. Only complaint is that the o connectors are really hard to clamp down and the rcas are kinda cheesey but work

Huge

I have never ran 0 gauge before and when I got it and took it out I was surprised but the big wire didn't really hurt the install it is still hidden under the carpet and it's thick and flexible so it was easy to run through the firewall. Now I'm gonna get the Belva big 3

True 0 AWG!

Pros:
This kit comes with everything you need for a 0 AWG amp install with RCA inputs.

Cons:
NONE

I would definitely recommend purchasing this kit if you need a quality 0 AWG kit at a fair price with super fast shipping!

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.

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.

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!

Belva BAK02

For anyone looking for a budget amp kit, this is it. It is TRUE 1/0. I even measured it. Just got it in the mail after about 5 days total since ordering. Shipped very fast; thanks Sonic Electronix. Awesome deal, nice and beefy wire.

Belva Amp Kit

Good product. Quality parts.would recommend to anyone needing a 0 guage kit for a good price.

Great Value

Great items from this place, more orders will be goin from me.

GREAT KIT FOR THE MONEY !!

Good kit , ive seen better but not for the price . Well worth the money!

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.

By Derrell on July 1, 2016 Verified purchase

great amp kit

The power wire is real thick, looks like a great amp kit, Rca cables look awesome. Only thing that would make this amp kit better would be to include speaker wire. Crimp terminals are a bit hard to install
But over all great amp kit.

Great kit

The kit is good has mostly everything you need
, although I recommend getting a longer ground wire due to it being short , only downfall other then that great kit for a sub amp n other amp install worked great for my sub amp and 4chanell although I needed a few more wires for adding the second one

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

Works just fine!!

No problem with install or power. Everything needed was right in the kit. I would buy this again if I needed it!

GOOD KIT

IT IS A GOOD KIT FOR THE MONEY. THE TERMINALS COULD HAVE BEEN BETTER. THEY COULD HAVE SUPPLIED BETTER 0/1 GUAGE TERMINALS THAT WERE EASIER TO USE BUT STILL A GOOD PRODUCT.

Real heavy duty kit. Real amount of 0 Gauge included.

This is a very heavy duty amp kit. The wire is huge compared to other brands I've used in the past. It's flexible and easy to install. And it's really a lot cheaper priced than other top brands. The fuse holder is nice too and I like the color of RCAs. Like everything with Sonic, always fast shipping and great stuff.

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.

Order

Never revieved I have a trache and am unable to speak on phone I sent you a letter but no response yet it wouldn't submit my review till I checked start I can't answer when I have not recieved it.

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

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.

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.

By David on October 18, 2016 Verified purchase

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

not what u expect

I would not recommend this product because. It I only a little bit bigger than four gauge. I do not know how they market this product as zero gauge. Next time I just have to spend the extra couple of bucks.

Budget amp kit *thumbs up*

This is a good quality budget amp kit. Power wire is almost true size and soft and flexible. Everything was exactly as described and no issues at all getting my system installed with this kit. The twisted pair rcas are nice and I have no noise pickup with them. There was even enough power wire left over for me to grab a few extra ends and do the big 3. Definitely recommend.

Great Budget kit, with a few shortcomings.

Overall this was a very good kit, with thick high quality wiring and heavy insulation. I saw no factory flaws, and since installing it I have had no problems. It did however lack a few things, which bugged me. The first was that neither: the ground, nor the power cable came pre-clamped, this wasn't a huge deal as I had access to a vice, but for those with limited tools, they may have trouble creating enough leverage to cramp the metal ends tight enough. Other then Having to clamp the ends myself (again, only an annoyance if you don't have access to good tools) the kit has performed flawlessly, and is a great value for the price.

Good Wire

I was skeptical about buying this wire, but to be honest it is definitely worth the money. I would invest in some new RCA's though, the ones that come in this kit aren't that good!

Great Value

never bought another brand. belva has always been easy to use and held up very well

AWSOME PRICE

Very good quality. Very flexible wire. Very pleased. Will be ordering again when i need it

Pretty good

It was hard to install but when I did I got the extra burst of energy I need

bIG OTT

It is a typical wiring kit for a system. It is a little short in my 03 suburban, so I just mount the amps under my sets directly behind the drivers seat.

Good for the money

Bought this kit because of cost. Fuse holder is of good quality. RCA cable is nice. No noise. Plenty of remote wire for amps. Power and ground are very flexible. Wire gauge is a little smaller then zero gauge but not like some other kits. All the terminal connections are included. In the end, good product for the price.

Wire is great but terminals are hug

The wire is great and seems to be true 0 awg. However when going to crimp the open barrel ring terminals to it they are literally twice the size! Have to go buy new ring terminals that are the proper size.

Sounds awesome

I installed these in a SubThump box for 2013 silverado. powered by Rockford Fosgate R1200.1D amp at 1 ohm I like headroom so this setup works great.. They rock hard!!

Best quality for its price!!!

I've been using this kit for about a while and the products are still in great shape. using it to power my audiopipe 3000.1D amp and two american bass xfl 15"s. wire in never hot. flexible. but the wire easily spreads apart for the cut tip/end if your not being careful and makes installing into amp/fuse box, etc ... more difficult.

Belva BAK02

Installed this wiring kit three weeks ago, very nice quality 1/0 gauge! Works great! Ended up buying some screw ring 1/0 gauge terminals because the crimp terminals it came with are a bit difficult to install. Other than that, very good product!

wiring kit

Great kit for the belva bb5000 wire size seems small but i just used it for the big 3 now im running skyhighwire still a great kit for a beginner just not for me

Excellent!

I bought this for my husband for his birthday and he loves it!

Durable

This is really nice and gives my amp the power it need to function haven't had no problems with this kit yet.

Can beat the price or quality

Nvx makes great woofers the hits every bass note. I would recommend in the future.

Great Quality

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.

Larry G

This wiring kit fulfilled my expectations . No noise interference and very high quality product !!!
I highly recommend this kit for anyone installing an amplifier in their car !

Simple and great product

This was a cheap and effective solution to hooking up my system only thing is it isn’t true 0 gauge wire however it does the job and I would recommend it.

GREAT SUBWOOFER : AWESOME LOOKS

I have two of these in my dodge ram pu. 5 cf box tuned to 29hz on 1300rms. It slams and sounds great. Get them, you wont regret it

Says 1/0 gauge probably more like 2/0 gauge. Comes as you see in pictures.

Good Value

Good value for a 600 watt RMS subwoofer. I would prefer a replaceable dust cap and non foam surround but for the price it's worth it. I also wish it included leads for various wiring conditions similar to what Alpine provides.

Good item. Did the job like it was supposed to. Would purchase again from sonicex

wow got jipped

this wire kit is nowhere even close to 1/0 gauge. even if it was pure gold it is probably a strong 4 ga in a 1/0 wrapper. very flexible and nice looking. the fuse holder isn't too bad. eh, i got it on sale.

By Brandon on April 15, 2016 Verified purchase

amp wiring kit

this wire is seemed mighty small to be for being 0/1 gauge wire but still getting alot of wire for the money. just be ready to buy end for this wire to hook up your cap/amp because this wire for me was way to big to fit in any of the amps/caps holes/connectors for wires

Worth the money

I took a chance on this brand of subwoofer and glad i did.. they look great.. built really good.. and hit pretty hard.. haven't pushed them yet. Gotta break it in. They sound really good in the foxbox for a 4th gen ram.. perfect combination. Powered by a pioneer gm-d9701 at 1ohm around 1000watts rms

By Joel on January 10, 2024 Verified purchase

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.

By Dizzy on December 24, 2023 Verified purchase

Good Value

Seems to be a good value and plays rated power no problem. I’m not a fan of foam surrounds because of durability concerns so that’s the only minus.

Good kit

For the price this item is great. It’s half the cost of a true 100% copper amp kit, which is why you get copper aluminum mix and cheap connectors. But like I said it’s perfect for the cost and works great

True 0 gauge

This is exactly what it says it is. I measured the wire itself at slightly over 3/8 inches. Which is exactly what 0gauge is. There are brands out there that are thicker, but they are oversized. Several companies make oversized power cables. But this IS true 0gauge.

nvx makes great stuff. these are not as robust as the last ones.. but non the less nvx and sonic are great to deal with. i installed the old one and the new one into a buddys car after getting a bigger amp. they do impress for specs and cost

Exceeds expectations

I tried a pair of the 10” version in a sealed box and was less than satisfied. Went with one of these in a ported box and much better. My last vehicle I ran 2 Massive Audio Hippo XL 8’s and this single 12 is close at a much cheaper cost and less power needs. This series of NVX subs are great for the price in ported enclosures.

Good Kit

This kit came with everything I needed to upgrade from my old wiring kit. It had a few things my old one didn't that would've been helpful if it came with some directions of sort, I figured it out but would've been nice. Also the wire terminals could be alittle better quality.

great bass

very happy with the sound that what my truck needed thank sonic electronix for your help in choosing this subwoofer.

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.

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.

Impulse buy may be a keeper

This is by far the largest and heaviest and most expensive piece of equipment I may ever own, at least value-wise, cause at 190.75 (after tax) I practically robbed sonic.

This is a first impressions review as I lack the resources to install and subsequently use this amp, I will post another once installed and slamming. I've always thought of powerbass as a lower end audio company... After seeing this beauty, I clearly misjudged, however I do feel like I cheated on NVX, being a huge fan of NVX, after I repair the damage done to my credit card (minimum wage FTW) I'll probably pop in the VCW subs and listen to this baby slam and thank Sonic and God for this incredible deal on such a marvelous pieces of creation. I don't do any flashy lights or sporty looking amps, I like the ones that look sleek and professional and exactly like this.

By Charles on May 3, 2016 Verified purchase

Awesome amp!!!!

Dude I honestly didn't think this amp would be as good as it is but it powers 2 of my subwoofers down to 2 ohms without a sweat! Before this I was running a 300 dollar amp that burnt up so I figured why not try something different so ordered this up, popped it in and my subs are louder than I've ever heard them before. My buddy is going to get one too with a similiar setup and we cant wait to put his in with a bandpass box to see how it sounds. On mine I have the battery upgraded a little and thats it but i dont see any lights dimming or electrical issues even though its rated for 1200 watts. If you dont want to spend too much on an amp but need it to dump power this is the best one ive used to date. A++++++

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.
