Wire

This wire is silver tinned IFC and is true to spec. Heavy duty jack and a high strand count for easy installation. Best wire I have ever purchased.

Great product for your $

Its pretty good package for installing amplifier i recommend this if you're looking for good wires for your system

nvx ftw

Nvx is my go to manufacture for everything all there products give u the most bang for your buck

A+

Quality wire, built to spec. Highly recommended. I used NVX wires and accessories for all of the electrical in my car. Did the big 3, have about 40FT of 0/1 gauge NVX wire and 50FT of the 16 gauge speaker wire for all of my speakers. Very happy with the results.

great speaker wire

Excellent speaker wire an is true 12 gauge very durable and flexible gave my subs the power it needs I was impressed with it

Good stuff

Ok they say "wire is wire" if that were the case monster, streetwire and a few others wouldn't be so expensive. This review is based on response of professional installers. My guys were so impressed with how NVX makes my system sound.

works well

this cable is super durable!!! i recommend it its high quality just as stated... it is a little difficult to cut through and to size or strip but it has a double jacket allowing for long life and will take most any type of regular wear and tear

Great stuff

No disapointments at all great speaker wire I love Nvx equipment

Great Wire

I ordered this because I wanted to try this brand. I was surprised at the quality of the product. Arrived fast to. I recommend this brand to anyone who wants good, flexible and reliable wiring.

Nice speaker wire.

I bought 25' of this 12 gauge speaker wire to wire up my mids and tweets. This is good size wire with a nice thick jacket on wire and was perfect for this application. I would recommend this speaker wire to anyone.

This box kicks a**!

I have a 15" kicker compR, it works great with this box. Very good quality, cheap in price.

Nice Box

Very well designed Box. The carpet on this box is really nice and the box looks perfect. I have a kicker cvr 15 in this box and it absolutely pounds!! Oh yea and if you have a New body Style(04-08) f-150 it will fit in the space between the passenger seat and the rear seat with the smaller rear seat on the passenger side flipped up and the box will face up.

BELVA 15'' BOX

AWESOME BOX VERY SOLID AND FITS NICELY IN ANY TRUNK WITH ROOM TO SPARE

Couldnt Ask for More!

Purchased this box for my JBL W15GTI MKII. For the amount paid and product received, its a great purchase. Couldn't have built this or have it built locally for even close to the price. Is it as good as a custom ported box? Probably not but that would be subjective but I love the SQ coming from it now. Can't comment on the durability because I've only had the box for about a week but I do not hear any leaks or rattles from the box. Connection pieces are solid. But best part of my experience with this purchase was the customer service given by 'Justin'. Gave me a great deal and got it shipped to my door within the week.... Couldn't ask for more. Would definitely recommend it.

Decent Enclosure

The box works great for my new Polk MM 15". It's a little bigger than the recommended 1.5 cubic ft. but it seemed like it would suffocate in a box that small. At the 50 dollar price point you can't hardly build yourself one for that and this one has quality connectors and it's built solid. Definitely recommend to someone looking for a 15" sealed box. And Sonic was great with shipping and customer service as always.

W/ 15" Kicker

This is a great looking box. Well designed and built. The carpeting looks amazing. It's big, but fits perfectly in my '99 Durango. I figured I would have to remove the 3rd seat when I saw it, but there's actually enough space where it isn't even touching the seat or rear door.

Perfect

Fits very nicely into the back of my '90 Jetta. Could even fit two in the trunk if I crammed them together. Carpeting is very nice and so is the construction quality.

Great box

Great box. I bought this box that is great box, for the value. I really am the shipping was fast also.

good box

i have a 15" kicker comp and it slams. it fits perfectly in my grand am. the carpet is really nice. looks good in the trunk

Belva MDFS15

great price. nice looking box works very well. I have it in the trunk of a mazda protege.

Great Wire

This is great quality, thick wire. It's very flexible and handles decent power.

By Corey on April 27, 2015 Verified purchase

Very high quality wire!

I needed some high quality wire for my new sub install. This wire did not disappoint. Very high strand count, flexible and jacketing was very high quality. Don't hesitate to use this in a high end install.

Really nice sub pushing alot of power on it and great price

Solid Performance

I have seen a ton of great reviews and testimonials about the NVX brand so I thought that I'd give them a shot. the VSW's offered top notch performance with very clear and precise bass. These 15's pounded so hard that I thought that my rear view mirror was going to fall off... (maybe its a sign to buy some sound dampener). Highly recommend these subs. Cannot beat the price and performance

By Ronnie on July 18, 2016 Verified purchase

15n sub box

My son loves this box. It is usable in the space he has.

NVX real budget king

Bought two of these speakers (NVX VSW154v2) because I didn't have a lot of cash for expensive subs. They hit real hard and didn't take a lot of power.Once i has be worked in it plays just like or even better than more expensive brands. It plays the real low note yes though not very loud but it holds it own, even without considering the price. I am a true believer now. Works very well with the NVX amplifiers

NVX VSW154v2 (VSW154 v2)

Awesome sub I got it hooked to a 1500 watt monoblock hifonics amp thumps my little Malibu bout makes my rearview mirror fall off good job

In love with these subs😍

These subs are amazing. I used to think the bigger the subs the bigger the sound. But I was mistaken. These subs are a decent size but outperforms bigger subs. They pound. Hooked them up with a auxiliary battery, an audiopipe 15001D amp, and two 15" NVX and the are powerful. My neighbors came out their house and said it was rattling their walls😂😂😍😍😍

By Domonique on October 14, 2016 Verified purchase

pound that box

you get what you pay for, decent box, no frills, does the job, good construction. should've gotten a ported box though, waaaaayyyyy more sound from a ported box has been my experience, but what do I know, I'm just a consumer :)

Excellent Box

I put a 2000w Quantum Audio subwoofer in this box and it sounds better than ever. My old box was a vented box and can't hold a candle to this one.

The box is of excellent quality. Well built and solid. Very tight and clean carpeting. The pollyfill is well placed as well.

I would definitely recommend this to anyone looknig for a good sealed box for a low price. Can't be beat.

great box

the box is sturdy and good. the price and shipping were really great.

Morning,

Hello everyone,
If anyone is considering purchasing this subwoofer please don't hesitate to do so.
My first system I had dual kickers, and I was partly disappointed in their performance. I was in band in high school. Hearing different genres of music I don't think it responded adequately to all the frequencies. Now obviously disconncting from the power terminal I knew my system wasn't on. But I wasn't getting a full representation of the music.
My subs got stolen and I purchased this subwoofer, connected at 4 ohms, for 600 RMS (amplifier) output I am loving it's performance. For a subwoofer test song ( I like futures molly percocet song) I was extremely impressed. For all else, mainly I like soft rock and adult alternative (36 alt nation is nice), I can hear the music as it was meant to. Also It is less expensive and outperforms the more expensive subs in my opinion.

Excellent Box.

This box is a Excellent 15" Enclosure for the Price. Only reason i gave it 4 stars is cause the Wood is kinda cheap but still very strong. Definetly takes a beating from a Orion 15. I would recomend drilling the Screw Holes out. Other wise this wood may chip or Break.

Beast of sub

Running nvx amps and figured I try their subs.
This hits hard and low + very clear sound !

nvc 12 guage

man for the price that I paid and quality of this product couldn't get any better

By rafael on September 17, 2015 Verified purchase

Great bang for buck

Good price for the output this sub produces.
Great design
Pros: great quality, loud, clear bass, doesnt need too much power to shine
Cons:can't hit the low notes very hard but still can produce them.
I recommend this sub if you're on a budget and want a good quality sub. Make sure you use a ported box.

Just As Impressive As 4GA

I purchased this along with the 4GA NVX XW4BL20. You can see my 'With the Best of 'Em' review on that page.

This wire is on the same level as the 4GA.

It too has the nice wound bundles of wires, albeit only 3 for the smaller gauge, but the same quality is apparent.

The two wires separate with a little force, and it does not tear the shielding off either pos/neg wire.

Shielding is easy to snip and strip without losing (m)any strands of wire.

This and the 4GA variants have left a wonderful impression on me. Do yourself a favor and don't look any further for power/speaker wire.

By Robert on August 18, 2015 Verified purchase

great buy

had to get the right enclosure for them and then they really performed.. 10/10

By Sammy on July 25, 2016 Verified purchase

Great sound with a better value

I would recommend this 15" sub if you want great sound at low cost this is my fourth Nvx subwoofer I still have the others too. Thought I give a 15 a try and am very pleased with it so far. Had a box built to specs and this sub hits pretty hard I'm still in the break in period but it's impressive gets low and has a smooth bass response love the way this sub sounds

good wire , it works good, i like,it free with purchase

By Robert on January 11, 2017 Verified purchase

NVX= Quality. End of story

I'm currently switching my entire system over to NVX. I've purchased all the wiring, subs, box, and sound deadener and have yet to be unimpressed. Do yourself a favor.....just buy NVX and quit wasting your time and money.

Awesome

Such a good wire.... Flexible.... Nicely insulated and right on point with the price.

By Jonathan on February 10, 2020 Verified purchase

good wire

true sizing , double insulated , looks and feels good. also stays tight after being stripped back.

Great Product/Excellent Value

Very flexible for such a thick wire which made it easy to run through the car. Used this to rewire my subs, old wire needed to go. Subs sound cleaner and a bit louder. Great speaker, I will be getting the 16 gauge to run my mids and highs. Highly recommend NVX wiring of amy kind.

By Rizzlers on June 10, 2016 Verified purchase

great wire

this is an affordable wire that's great quality. The sound quality is awsome

By Gerald on January 12, 2017 Verified purchase

Surprisingly nice cable

Cable was 12 AWG as advertised. The jacketing consists of a soft-touch frosted rubber that's about an eight of an inch thick with a rounded side and a squared side. They are plenty flexible and the thick jacketing gives a little piece of mind that these would be able to handle moderately sharp corners under my carpet.

Really the only downside was splitting the pair with my fingers to separate the two cables so I could strip them. Doing that a dozen times got pretty old because they're stuck together well

Cool wire

Nice wire good and thick it also is flexible enough to run making install easier good quality

Well built for a pre fab box.Under braced like most "bought" boxes.I added 1 inch mdf strips.Comes with stuffing if you're into that.Overall,cheap enough and good enough to slap something together in a pinch for some thump.

Nice solid box specs are off a little.. Cutout is 14"

Cutout is 14"

Not Cutout Diameter: 14-3/4"

Worked out for me..

Solid Rock-Box!:)

I really like the non-ported enclosures, as they have a crisper bass, but need a little extra juice from the amp.....and when you punch the bass i have had 1/2" MDF enclosures tend to develop rattles in them and these are 3/4" SUPER Solid construction and haven't had 1 problem yet! These are built solid and very clean and neat with the professional carpet finish! Haven't even had the corners start coming loose, and I have 2 of them.
Thanks

Good speaker wire use it for my car audio looks like it was made with good material would recommend 9/10

Great item!

My son wanted this for his SUV. He has been very happy with the sound quality.

Great wire

I usually use knukonceptz oxygen free copper wire, but this wire came free with my subwoofer enclosure I ordered. The insulation is really nice, and the black/blue color coding is so much easier to identify than the color coding on knukonceptz speaker wiring.

Oxygen free copper, loads of strands, quality insulation and look. Would easily buy this stuff again

By Ryland on July 3, 2016 Verified purchase

Honest review

I received this box free with my sub purchase. I was planning on building a custom vented enclosure. Since it was free I wanted to at least try it out first. I upgraded from a 2 12 cheapo setup in a prefab vented enclosure to a single 15 NVX VCW in this sealed box. I'm still breaking in the sub, but I can tell that this is a great combo. The terminals, carpet, cutout, design, packaging, etc, was very well done. I cant give 5 stars for durability yet, but it looks like it will be good for a long time.

By Chris on February 25, 2016 Verified purchase

NVX VCW154 DOES NOT FIT!

The subs basket is too large for the box so I had to make the hole larger to fit the sub. Other than that the box is nice

Nice done!

I got this for my 15 boss. Hit pretty hard together. Awsome box

By Max on April 23, 2020 Verified purchase

Excellent wire

Very good quality wire...I am hooked on NVX I have purchased speakers, subs, amps, equalizer, installation parts, and wire so far every NVX product has much exceeded my expectations. I'm just waiting for them to start producing head units so I can get one and then my entire system will be exclusively NVX! You hear me NVX?!

Does the job for the price

The box does the job for the price but if you really wanna beat down the block you need to get one of those ported/vented boxes

By Nathan on January 16, 2018 Verified purchase

I purchased a sub and received the wire as a bonus. It would still be a great deal at regular price. It is ofc speaker wire . It is extremely flexible and easy to work with . NVX has not failed me yet with any product of theirs that I have tried so far.

By Casey on March 22, 2020 Verified purchase

Solid construction for price

Clean and solid construction inside and out. Quality materials and fit. Only issue is that the "carpet" is more of a felt-like material that is lightly glued. Good enough for home or car use, probably not for pro use. Totally great for the price.

Great buy! Put together well and everything I was hoping for

Im really happy with this box, would definatly recommend!!! Well built and would buy again

By Anonymous on November 4, 2018 Verified purchase

Good deal

I recommend these 15s over any of the higher priced subs because;…. Well there badass!! Enough said ???? I’ve got 4 nvx 12s and soon to have 4 nvx 15s already have 2 that are 15s to go with the 12s in a fosgate 1000.1 and the rock on any music played! Thanks sonic electronics for the great sound ????????????????

Would definitely recommend

I’ve worked these subs pretty hard for the past two months. For $xx a piece these are way better than I expected as far as lows and duration. It takes a good amount of abuse to heat up or begin to smell. Please keep in mind that I’m sensible with them as far as pushing their limits… but I like it loud and I drive long distances a lot. Aggressive drum and bass is my jam so I have killed many many budget woofers over the years. These are holding up well for a budget system in my work truck. I have them in the suggested 2.75 ported box. Pushed by a Rockford Prime 1200 at 1ohm. Very satisfied so far. Will definitely support NVX again.

So underrated and this sub slams. Was surprised how hard it hits.......especially since its a 15

By Cameron on August 8, 2021 Verified purchase

Incredible Sound Quality for the Money

I absolute love this sub. It could easily sell for 3x it's current price. I've got it in a pre-built Belva sealed 1.9 cuFT enclosure with polyfil. It's being driven by a 1000W rms amp (probably actually putting out 600-700W) and it's a perfect match. It is extremely accurate and precise. Very flat frequency response, too. It gets all the way down to ~35Hz loudly while still accurately producing the punchy bass around 100Hz. (It starts dropping off lower than 35Hz, would likely hit lower with a bigger box, but maybe less accurately). Overall 10/10, especially when you consider the price.

Larger than what Crutchfield installed

Like the title, had a previous 500watt sub installed with 16awg low voltage wire and this filled the void I was missing out of my subwoofer.

By Cory on February 8, 2024 Verified purchase

Great sub

This is great sub never had a issue with it it needs a good amp to push it I had it in a vented box definitely would buy another one

By Daniel on December 20, 2022 Verified purchase

Best Value

While looking for an efficient 15” Sub that would play well in a 2.2 cubic foot sealed enclosure I narrowed it down to this VSW subwoofer. At a price point around 100 there are few other 15” subwoofers out there that I considered. These seemed to have good review on sound quality and based on the data on Sonicelectronics website this have good F3 response below 40HZ in a 1.75 cubic ft or larger enclosure. I now have one in my vehicle and I am very impressed by the low end response and the ability to transition to quicker bass tones. Very smooth sounding speaker with high efficiency. Running 600RMS to the unit is more than plenty. I highly recommend this subwoofer.

By Joe on November 13, 2022 Verified purchase

Superior quality!

This wire is excellent, top quality coming from Sonic Electronics house brand! The strand count and craftsmanship is the upper echelon when it comes to car audio wire!

By ColbyG on May 12, 2024 Verified purchase

Awesome wire for awesome price per foot

Everywhere I price for 12 gauge was just getting out of hand. I needed some for my jl subs I got. Let say separating them to single strands was a breeze for my install and jacket was nice and thick for protection flexibility was amazing to bend them pretty much into a u shape if you needed to. And ofc selling point then that cca.
