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.

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.

BELVA 15'' BOX

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

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.

By Rob on December 10, 2023 Verified purchase

15n sub box

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

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.

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.

nvc 12 guage

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

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 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

Premium Wire

Very good product. I was looking for a #12 gauge quality speaker wire for my home stereo system. This worked perfectly. The length sent was as expected and delivery was fast and prompt.

Bella enclosure review

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.

This wire is top-notch. I’m not an expert, but the quality is the best I’ve seen.

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

Wire

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

Great Value

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 ken s on January 12, 2018 Verified purchase

Nice wire

I needed new speaker wire for my 2 sub boxes which i was putting 1500 watts thru and didn't want any resistance.

Thanks, sonic for fast delivery and for a great price.

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 Brock on May 7, 2020 Verified purchase

High grade cable!

NVX has impressed me many times and this cable is no different. High quality cable and overkill for what I need, but I like overkill.

will get the cops at your house

good sub had it for a week now still breaking it in ,but turned it up today and a old guy 5 houses down said hes gunna call the cops if i dont turn it off ...worth the money . ive had memphis pr 15s and 12s and pioneer tsw306dvc 12 s and the alpines are better, im running 2 on a memphis st 1000d (1100w rms ) hits hard and low

One of the best sub wires out there

Made of very good quality and strong materials. Works great with my RF T1S1 subwoofer.

By James on February 4, 2023 Verified purchase

Great Box

It's a great box for a 15 inch subwoofer. I prefer a sealed box for more space in the trunk.

By Jordan on September 22, 2022 Verified purchase

Extreme Bass

It's simple, I am the envy of my friends eyes and ears. I truly dominate the sound system battle at my school.

Great Sound

I haven't owned any of these new Type S subs by Alpine yet, but they do have them in my local store. They had it powered on an Alpine 1000 watt amp and the box they used was ported. Sounded pretty decent for 15s, but could probably sound better in a sealed box. I would recommend these to those who love Alpine quality and speaker/subs.

Nice sub enclosure

I have two of these in the trunk of my 2015 civic with rockford fosgate p3's

By jeremy on February 28, 2023 Verified purchase

Sounds good to me

Had this sub for about three months. Shipped from sonic. Break in period was a breeze. It handled every bit of 500-700 watts without a hiccup and sounded pretty decent in the trunk of my car in a 2.6 cube groundshaker enclosure. Had the right about of boom with Rap and punched like a sealed with Rock and handled all the dubstep I threw at it without skipping a beat. Alpine defiantly has a unique sound that I certainly approve of. Good sounding product for the money. I would say buy if this sub in this price range if it appeals to you. Should be no disappointment.

Very strong

Pros:
Very efficient
Loud on low power
Can handle more than rated RMS (If your careful)
Alpine quality

Cons:
Stinky when there breaking in.

Loud

These subs are incredible i have them in a custom 5 cubic ft box tune to 35 hz an these things slam. A great buy for someone who wants some serious bass.

Amazing for the price

I purchased on of these a few months back and it slams. powering it on an Alpine MRX-M55 at 2 ohms, 550 watt rms in a ported box to 32hz. it sounds amazing and hits harder than anything I've owned before. You can't go wrong with this sub.

Great!!!

Have 2 of these in a sealed box on just 250 watts a piece and man these things slam!!! Going to get 2 more when I get the money.

Best sub ever

I have had the type r 15 and this one sounds waaaaaay better. Alpine is the best period. I have one running at 500 rms and I can't use any mirrors at all. My rear deck by 6x9's does the wave. It's in a 2 cu ft sealed box and loves it! Love you alpine and sonic!

great price

This sub is a great deal. I have it in my 2008 Tahoe with a punch mono block and it bangs hard! It knocked of my rear view mirror off twice.

Question

Does it sound good in a ported box? If so please let me know I'm wanting to buy one

Great performance for a budget sub

Considering the low price of this sub it is pretty amazing. I would however ding Alpines quality controll. There are several locations where excessive amounts of glue are visible, which can detract from the cosmetics of a high end installation. In its price range, nothing compares IMO... as for performance, I think it is comparable to my Hertz hi-energy 15 which retails at $899...

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

Amazing

I have owned two of these woofers for about 2 years now and they are still playing like new. they sound great, hit hard, and are a great buy.

info

great product that has good sound quality and a lot of output. doesnt play the lowest frequency notes with authority still a really good value just depends on what you'r looking for

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!

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.

These really pound!!!

I have 2 12" inch wired to 1 ohm and taking 500 RMS to each, they definitely pound in my sealed enclosure.

Great Sub

A great sub, I had one running on only 350W for a while and it gave great bass. I just added a second and got a secong amp to run them at 600RMS each and they sound AMAZING. Even in sealed boxes these things are super loud. If your concerned about the 24hz basement dont be. Just be sure you can run 8 gauge wire to them if you intend on running them at full power.
