Customer Ratings & Reviews

BAK 82

Nice package, quality wire but could more end connectors for the larger wire.

Good product

It's exactly what you need for your car amp installation. I bought this kit with Kenwood KAC-1502S amp for 75 bucks. Good deal from Sonic Electronix.

Great kit for the cost

Very nice kit for $18.
Wire seems adequately thick. Good quality fuse (not AGU) and fuse holder. RCA's feel durable. Decent assortment of accessories. All together a solid budget kit IMO.

Don't know what the other guy is talking about.

This kit was awesome and included with my package that I bought. In comparison to others for the same price, there is simply not a comparison and the other review is just wrong on so many levels I felt compelled to write this.

The reality is there are a lot of real shoddy amp kits and wire as a whole being used in car audio in terms of cheap amp kits that have over-insulating wires and fake gauge ratings, huge amounts of aluminum, lousy RCA cables, fuse holders and other accessories. BUT and a BIG BUT, this kit excels in those areas where others fall flat on their face. I have bought a few inexpensive 8 gauge kits in my day and XScorpion, Raptor, Install Bay and others haven't even given me the 8 gauge of wire that I paid for, and in some cases gave me wire that heated up to a dangerous level due to the actual make up of the wire.

I also literally laughed when I see that the other reviewer was intending to use spade terminals to connect his amp power and ground wire... It is for the SPEAKER wire knucklehead :-). I am an installer and the smaller accessories work just fine when you use them correctly. Most amps will still work with them when used with the speaker wire. Of course one can be used for the remote wire connection to the amp and the other end with the butt connector being used to connect to the stereo. The funny thing is, if you do not need them, who cares? It is like ordering this kit for a compact car or single cab pickup. You will not use all of the power wire for these applications, so do you complain that the manufacturer gave you extra wire? That just made me laugh.

Now, onto the other accessories. The AFS fuse and holder that are included are so far superior to others in this price range and the amount of copper (albeit CCA) is much better than others in the price range. Lastly, the RCAs included are awesome for the price. I cannot find ANYTHING to complain about here for $21.99.

All in all, you will not get a better value for the money.

Good product for the price

Good wiring package, good quality fuse holder and wires, I would like more connectors on it and maybe some tube for the power wire, but overall is a good kit.

Good Purchase

I used this kit to install a 2 channel Boss amp. The quality of the pieces in this kit is five stars, but I'm giving it 4 because it is my belief that to do a clean install you need (4) 8 gauge terminals (one at the batt, one at the amp, one at ground, one at the amp), not just two. I had to spend an extra six bucks at Orchard for the extra terminals, but since the cost of the kit here at Sonic was only $20 at the time, it was still a good deal.

Good kit

Good kit for basic setups. Using it right now in my mothers system powering a simple 12. Could handle more if needed.

Pros: Handles power, Wires are HQ, More copper than rubber, Wires are good length, Fuse is HQ, Comes with lots of ties and rubbers.

Cons: None

I would recommend this kit to anyone who has a simple system. All around good kit.

Great wiring kit

works great on my MB Quart 2x100 watt amp.

Good Kit

Great kit for the price. the price is good. Long wires.

Belva BAK82

Worked very well for the money, great value for my system! Only thing that kept me from giving this 5 stars across the board is the design of the fuse holder and how you have to change/connect the fuse, minimal complaint.

great wiring package

Great wiring package for the price, everything you need is included. Sonic has the best prices that I could find anywhere.

Worth it

This one is good try the four gauge amp kit

Price is right

This wiring kit is very good quality. Although this was my first subwoofer install, I consider myself an expert when it come any kind of stereo hookup. This kit comes with everything you will need for a professional install. I installed a MTX self contained in the rear of my 1999 Explorer Sport. This kit made eazy.

Exactly what you need

Comes with everything you need, literally. Ring terminals are good quality, insulation is very good quality on the wires, fuse is good quality, currently connected 2x 600 watt Pioneer 6x9 speakers to a 450 watt amp (250RMS) with this wiring kit. Plenty of length to get from the battery to the back of my car. For 21$ this is a steal! Does its job, does it well. Highly recommend this, you won't beat this price for everything you get.

get's the job done

This amp wiring kit did the job. Fortunately there was just enough wire to make it from the trunk to the battery in our honda civic sedan. A larger vehicle may have been a problem. The kit came with almost everything I need to install a self powered subwoofer/ amp.

Belva BAK82

The quality is good and everything I needed was there. All of the fittings were good. More than I needed. I would recommend this product because it delivers as claimed.

Cheap - And it is

The wire is fine, the RCA cables are fine, but the terminals they give you are worthless, not enough of the 8GA size for both ends of the wire, and there are a bunch of small ones that werent even needed.

Excellent product for the price

I'm not running a sub or crazy rms wattage. This kit is more than adequate for my set up. 60 watt rms fronts and 80 watt rms rear speakers. The amp is 75watt rms X4. I would definitely buy this kit again for any similar set up. Plenty of length for all wires except the ground. If you are mounting the amp to the back of your rear seat and it folds down, make sure the ground is connected as close as possible the seat. Other wise the wire will prevent the seat from going all the way down. Wasn't paying attention to this. Bent the ground terminal on the amp when I folded the seat down and it hung up on the ground wire.

Cheap and does the trick.

I bought this for my gf trying to save money, it handles power fine and doesn't distort. Very happy.

good quality

Used it in my truck for a small amp came quick and easy to use would recommend it for anything from daily to comp use

easy as

Bought this kit with the Pioneer TS-SWX251 sub/enclosure and the Kenwood KAC-1502S amp it includes more than enough cabling to run the length of the car and looks to be good quality cables.

Good deal for the price

this wiring kit comes with all of the nessary components to put in a small amplifier. great value.

Belva install kit 900 Watts

look like quality wires nice and heavy!! more rubber coted than plastic may last longer??

amp kit

Nice amp kit for the money. I have used this kit on about 4 installs and will keep using it.

Came free with Kenwood amp, works fine.

This wiring kit was included for free with my Kenwood KAC-1502S amp that I use bridged to drive my Pioneer TS-SWX251 sub. It is a decent kit. The speaker/power wires are copper-coated aluminum which is just so-so. But it does include everything I needed to wire up my amp (fuse kit, zip ties, wire terminals, etc) and it works totally fine and I doubt I'll ever have a problem with it. So while theorhetically the wires could be higher quality, practically speaking I doubt I could ever tell.

did the job

Had all the wiring needed and a little more. wiring feels flimsy but it works !!

Great wires a pain to cut

The length of all the wires was perfect for my VW gti to set up an amp. However they are a pain to cute and strip. The rubber coating is very stretchy. But they work great. I do recommend these for the price. The connectors for the ground and power wire are crap. They do not like to stay though. Once you get it then they are good.

Good enough

Overall, this is a decent enough kit for an amp install. Fairly run-of-the-mill kit - my main gripe is that some of the prong connectors are incorrectly sized (amp connection for ground and power wire), but all other connectors are good. Zip-ties are garbage, but that's pretty much expected as well.

Wiring 101

Pretty basic kit, I would recommend it but based on my application I needed some larger capacity connectors than what were provided.

Boa qualidade

Muito boa qualidade, e muito barato vale a pena, a qualidade é incrível

It Works!

Everything worked as it should and this kit had lots of wire to get the job done!

Install Kit

Very impressed with this kit, had everything I needed for a clean install. Glad I purchased it.

Good Product

This kit seemed to me to be a good value kit. I felt that the connectors and one of the cables was of a cheaper grade than what I would prefer. But I feel that it was priced accordingly. The product met my needs, except for me using a better quality crimp-on connectors.

Great Value!

I ordered these items for my grandson, to go along with other items. He loves the system.

good deal

everything you need is in this kit and for me there was more then what i needed.

perfect kit

Made the install happen much faster. Everything was easy to work with . Very good quality. Real happy

Great box

I love this sub box. It looks & sounds amazing I am so happy I got it . If you want a box that looks and sounds really good you should get this box . U will love it as much as I love mine !!!!

Good box!

It handles my sub woofers pretty well! I'm surprised it is holding up so greatly! Highly recommend it to anyone!

NVX for the win..

NVX Tweeters, Midbass and now the Subs, I believe NVX is firmly committed to SQ and offers a great product for a tremendous value. This subwoofer is their 2nd Generation and has the non-pressed paper cone, i spoke with NVX why they switched from Polypropylene to Paper and he told me lot's of reasons but mainly SQ and after listening to the subs for an extended session i have to agree that they sound fantastic in a 3.2 cu ft vented enclosure with 50 oz of polyfill, i can't imagine the SQ getting much better than it is right now and close to 130 db's is plenty loud for me, my ears are still ringing..
Each sub is wired in series for a 4 ohms then both subs are paralleled for a 2 ohm final load impedance on a 500 Wrms channel, they pound the ground and shake my entire full size van, much louder than the MTX Terminators that were replaced and i had to cut the bass knob back..
I highly recommend these subwoofers, the 1st Gen subs got lots of 5 star reviews and once people catch on to the 2nd Gen they will too, am extremely happy with my purchase and have nothing but good things to say for the NVX Brand speakers and subwoofers..
NVX for the win, the VSW122V2 is probably one of the best under $70 subwoofers on the market and i wouldn't hesitate to use any of their products..

Decent kit

This is a decent kit for a budget stereo system. Only one issue though, I was hooking this up in a Ford expedition and wires were too short to put the amp were I wanted it. Will pay more attention to wire length next time.

Nice and inexpensive

Good little amp kit for the money. Wires are flexible and it comes with everything you need to get an amp going.

By Kenneth on August 13, 2015 Verified purchase

Great box but it's to big

I would recommend this product, I like it alit except it's to big to fit in my trunk and had to put it in my back seat, so make sure you measure before you buy a box

By Nick on April 12, 2015 Verified purchase

Good starter kit.

This wiring kit is good enough for the basics if you don't want to spend more money or chase around assembling the wires you need for a basic system hookup.

Well Built, As Advertised

This kit was included with a MTX package that I ordered. It was as described and is a well made wiring kit. Installation was quite easy and delivers adequate power to my system with proper grounding.

My only complain, I drive a 1997 Buick Park Avenue, and the 17' of cable for the power line wasn't nearly long enough for my installation. As my amplifier is currently mounted in my trunk due to limited options for locating it elsewhere, I had to go to a local electronics store and purchase another length of 8ga wire, an in line fuse block to splice the connection, as well as an additional fuse to ensure the line is properly protected.

For those of you will small cars, or who chose to mount the amplifier somewhere in the cab of the vehicle, this will be more than adequate. For those with larger cars, or luxury vehicles who are mounting their amplifier on the box or in their trunk, be advised you will need more power cable.

By Jeromy on July 23, 2016 Verified purchase

Good Product

Good Product it could be better if it included ground , power , and turn on connectors for better connection to amp.

By Jency on January 17, 2016 Verified purchase

Great sound

The bass from this sub is deep and clean. The mounting depth is efficient for almost any 12 sub box. I'll recommend to anyone that want clean sounding bass.

Pros - Well built, sounds good.
Cons - None so far.

Nice subs!

Hooked up 2 of these to my 1000 W RMS amp with the gain turned down while I break them in. Sonic got them to me right on schedule, and they sound great so far. Dual voice coils are a great feature and I can see the quality built into these subs. Using a sealed box with recommended volume of 1.25 cu.ft. per chamber during break in, so far I don't think I will need to move them to a ported box after they loosen up. Great SQ at this power level, nice subs at this price point.

By kjbad on July 27, 2016 Verified purchase

Solid choice

I put one of these in a 1.25cuft box in my accord on an mrv-m500 wired to 4ohms and tune the amp to put out 300tms with my multimeter. Gotta say; at only 300 watts this is pretty impressive. Still fairly tight for a 12" but plenty of bottom end for what I usually listen to. I'm planning another build but two of these next.

Good entry level subs

Easy on pocket and they hit the lows with deep rumbling bass

By kenneth on December 31, 2017 Verified purchase

Great place to buy

Awesome system easy to set up and ridiculously cheap! I love it

Solid gear

This sub met my needs perfectly. I needed a low cost high quality driver with reasonable efficiency. I also needed to be under 5 inches top Mount depth. It fit my truck box for the tundra crewmax behind the rear seat perfectly and gave me plenty of clean bass. Only time will tell if it can handle the abuse to come. I'm using a rockville rxa t1 to power it. It's a great match. Cea compliant to match the sub and pushes it to the limit as well.

Great entry-level subs for the price!

I purchased these last November as a black friday special after a fitment issue with the pioneer champion series that came with the bundle( I know right?). The customer service rep spoke highly of her brand and I went with his recommendation for these NVX'23r hrs. I installed them into a nice 2 sub ported Belva box with 1.75 cubic ft per sub tuned at 40hz. Wired them in parallel 380 watts @ 2 ohms to my NVX JAD900.5. I broke them in out of the box with a single tone generator because I wanted to bang asap. They sounded great in the trunk of my Monte Carlo for months. I then put them into my Mazda 3 hatchback faced upward using the same amp.* I thought one of the subs blew because of it making a terrible rattle and only ran one sub 210 watts @ 4 ohms. After 3 months of only one sub, I found out that the dust cap came unglued. The cone was still nice and glued, so I bought some clear speaker adhesive and fixed my issue. Got both of them hooked back up and forgot how loud both of them were together. I really enjoyed my time with just one sub because it didn't bang as hard and fell in love with the sound quality. I play all sorts of genres from rap, EDM, dubstep, house, metal,to alternative. They can play anything I throw at them and do it accurately. A bunch of expensive name brand subs aren't even capable of going below 28hz and these go all the way to 20hz. While it may not produce those low notes loudly, their presence is there and can be heard clearly. One day I'm considering putting more power to them or a higher end NVX sub one day, but these will definitely put a smile on your face, even with only 200 watts each. Go ahead and get at least 2 of them. You know you want to!

I'm removing one star for the dust cap coming unglued. Everything is working great since I glued it back.

Awesome Value

I bought this to hook up amp, everything I needed came with this kit
Worked great!!!

Came with bundle rated too high for these cables

I bought a bundle that included these cables (1kw) along with an amp (1.5kw) and 2 subs (1.3kw). Didn't make sense to include these cables, since their recommended throughput is much lower than the other components, so I never used them. They look nice, though.

By Ken on April 19, 2018 Verified purchase

Good deal for the price!

Kit has what it says. Most of the wires are of good quality, but the remote wire could have been a tad thicker. It broke every time I tried to attach it to anything. I ended up using some leftover speaker wire to complete the job. Overall though, you can't beat the value.

By stormyknight on September 8, 2016 Verified purchase

Great Price

This amp kit works as needed, it has everything needed for a basic amp install, I would recommend it for anyone needing a lower priced kit. Just make sure you get the correct gauge wire kit for your install.

By Chad on February 17, 2020 Verified purchase

Entry level... my foot!!

These babies Boom! Amazed by this entry level sub from NVX! Great SQ and loud! I have been through a lot of subs. These rate in the top 10 with me! Thanks Sonic!!!

Box killer

Ok fair warning these subs will kill your box if it is weak. Tuned my amp at 800w rms 400/woofer at Max volume. At 60% volume about 300w each. Very clear sound very nice low resonance. In my Sierra box choices are limited so I went with the generic box with about 2 ft cubed total. After about 3 weeks or so I started to hear a rattle and thought I burnt a coil or messed up a spider. Nope....I split my box at the seams. If you get these subs, take some of the money you save and invest in a strong box. They slam hard. Not loud but very clear and very hard. Definitely looking at putting a set in my wife's car.

2nd Kit I have Purchased, Still Can't Find a Better Deal

I had a 500 Watt amp and sub installed in my old car, and sold it with most of the wiring in it for the new owner.
I installed a new 500 watt amp in my new car with a new sub, and bought this same wiring kit as I still could not find a better deal anywhere else.
It's a simple kit, has everything you need, and makes installation of an amp/sub a breeze. Tonnes of wire length, I still have lots leftover thanks to a trunk-mounted battery. My previous car had a battery in the hood, and this kit still have plenty of length.
The RCA's are very nice, and all insulation is great quality especially for the power/ground. Ring terminals are easy to crimp, and were the perfect size for my battery terminals/main grounding junction.

By Vincent on March 6, 2016 Verified purchase

Everything you need

This is a basic kit that has everything you need and is pretty straight forward. No issues so far for the price who can complain

Outstanding kit

Loved it. Nice flexible kit. Good clean power! I would buy again soon.

Very Nice Kit

Sonic recommended this kit online to use when I bought a Kenwood Amp. At the time this kit was on sale at 50% off. Glad they did. It would have cost me much more to buy the wire and connectors and fuse separately. It came with plenty of everything to hook up my Amp.
Thanks Sonic!

Amp kit

I have bought different amp kits from other brands and wasn't satisfied with there products because of certain things.1 was price and 2 was the power amp wire where the fuse goes. The plastic part where the amp goes was crap and fell apart over time. I like the sonics amp kit because of both awesome quality wire amp the red power amp wire was awesome quality as well. I would recommend this product to anyone who buys this!

By Gary on March 12, 2020 Verified purchase

Great subs for the price

I bought 2 of these, put them in a 1 cubic foot per chamber sealed box with a pound of fill per chamber, wired at 2 ohms to a kicker cx600.1 and they sound great. Extremely clean and tight bass. They replaced 2 of the older alpine type s's that blew. They're not quite as loud but they sound cleaner and punchier. Also the alpine's were in a ported box, I think if I had these in a ported box they would be about the same. As for durability I've had them for about 3 weeks now I think, running just below clipping from the amp, for atleast an hour drive everyday and seem to be good and getting a little louder as they break in. I think the look and design are great. They look awesome in the box in the trunk, not too flashy but look like solid quality. Overall for the price these are a great buy. Would definitely recommend these for anyone on a budget like me looking to add some bass. And as always sonic delivered fast and packaged well with great prices, love the company, will be buying all my audio equipment from here.

This kit is much nicer than most in its price range. Even though the wire is CCA, it looks to be full 8 gauge. The fuse holder and RCAs look to be of decent quality, and the separate remote wire and extra speaker wire are nice.

But didn’t need it in the bundle. Good price for both though!!

NVX NSW122v2

I have been out of car audio for 20 years. All the basic principles still apply. These subs sound pretty good for the money they are a steal. I have them in a tight box poly filled with 325 rms. They hit as tight as 10s and still hit the lows fairly well. I’m guessing that the 1.25 or a little bigger would really bring them alive. I think with them in a little tighter box they could use 500 rms. No complaints the more they break in the better they sound.

Really good subs for 59.99 ea

I have 2 of these in a dual ported box running off the bda7501 amp and it is the perfect combo for what I am running. I was very impressed with sound when first installed each time I listen to them I have to dial back the bass remote because the bass hits so hard I think I'm going to blow a sub. I recommend these subs and the nvx bda7501 amp to power them.

By larry on March 12, 2017 Verified purchase

Bit of a disapointment

Dont get me wrong if your lookin for a clear sounding sub, then this sub is perfect. However i was expecting more of a boom, most music i play i can not tell i even have a sub.! Of course though if the song has low end bass it sounds ok.

By Robert on September 28, 2015 Verified purchase

Good starter.

For an entry sub, and for the price, it's pretty good. I put 2 in a custom box, tuned to the recommended he and air space for 1 sub, but the ft^3 multiplied by 2. It hits the lows good and can handle a a lot. I only have 400 watts rms to both right now but it can handle up to 700 watts rms safely! The wiring is a bit confusing, being that a dual voice coil subwpofer isn't exactly "entry level", but it's easy to learn and a guide is offered here on sonic. I'm satisfied with them so far and I would definitely recommend them to a friend and anyone looking for first time subs.

NVX NSW122v2 (NSW122 v2)

MVX NSW 12

I ordered 4 12" NVX MSW and the West Coast Customs edition of the MB Quart 1500 both from sonic. All super quick deliverys and no issues...
Clear crisp bass that gets pretty loud... I'm still breaking them in a little bit. I have them in a custom box tuned low (27 hertz) it's 10 cubes... (HUGE) way larger then recommended and tuned lower then recommended.
It still sounds good... Gets pretty loud and pretty low in the back of my mustang lol
I'm upgrading big 3 and going for a bigger set up...
All through sonic because prices are amazing and shipping is always on point

Very nice subs!

Ordered 2 of the NSW 122 v2 and very happy with these subs. Installed in a prefab box for my 99 Silverado ext cab and these things sound awesome! Still breaking them in, but even at lower volume they are shaking my mirrors and producing very impressive bass. For the price, you won't get a better quality subwoofer. They sound great with 1 cu ft per speaker in sealed box, and these are the "entry level" line of subwoofers from NVX. VERY IMPRESSED!

Showed up within 48 hours from ordering along with the downfiring box I ordered from Sonic, packaged well and for 13 bucks I have a 3 year warranty!!! You can't beat it.

Highly recommended

Pretty good

Installed these in a 2015 Challenger in a 1.25 CF box. They hit pretty good at the recommended power. Nothing insane but they aren't priced insane. If you want a budget sub these are pretty good.

By Derek on March 31, 2017 Verified purchase

Not so good

Had this sub in a sealed box to spec's on roughly 300 w RMS and it burnt/coils died. Yeah, don't say I did something wrong, I know better, been in this for over 35 years. It sounded ok, not very low bass but decent. Lasted about two weeks then it was off to the trash can. Once removed I installed a different 12" sub with a similar rating and it's been great. Not sure what the issues were, possible a defective sub, it can happen. I may try another NVX sub later, but as far, I'm not impressed.

Great budget sub.

I was looking for an inexpensive subwoofer to test out in a truck wedge ported box. I came across this sub and decided to give it a try. I've heard of NVX, but never used or seen one in a system. I must say, this sub is WOW! completely surprised how well it's performing. Its not made for shallow boxes, but it fit good in the box I had and it is getting down. I would highly recommend this for anyone looking to bass on a budget.

Budget bass

It’s a budget woofer not for competition it’s entry-level spend more on the next level nvx they’re great products love their lines of amplifiers.

By JORGE on April 24, 2020 Verified purchase

For the price, can not be beat

I have two of these wired to 4ohm in individual ported boxes and wired down to 2 ohms powered by Kicker CX600.1, the amp is certified at 668watts rms @ 2 ohms, i have my gain about 3/4 of the way, so I guesstimate they are getting 250 watts each. These subs sound great, The bass is deep and loud. I listen to rap and rock mostly. I have ordered another one for my wife's Nissan Rogue in a sealed box though. I recommend these if you are on a budget, or if you want to save some money. For this price, these subs cannot be beat.

Pros: price, value and great output
Cons: none at this time.
Cons: None so far.

By Dennis on December 25, 2023 Verified purchase

great entry levels

Have tried these in both sealed and ported after good break in period in a 2012 civic and 94 suburban both vehicles sounded good. Recommend boxes sealed or ported to be on the high side of air space. These speakers are pretty musical with good boom for what they are. l wired series parallel on a jad1200.1. After break in, tuning, clean power, and correct box, they sound great for the price. If you go sealed do 1.25 net with 1.25lbs poly fill. I would even go to 2 cubes ported at around 37hz. The other reviews just sound like they didn't know what they were doing. Especially the one that said didn't last a week. He probably clipped the crap out of them (could be wrong) but sounds like a kid that had all his bass boosts and gain all the way up. I say this because usually if you knew a little bit of what you were doing I feel these subs will definitely last longer than a week. My cousin bought 1 off me put it in a 1.8 cu box at 38hz with a punch 400.1 prolly getn 275 watts sounds good great combo. going hard for about 8 months now and still bumpin. So if your hesitant on buying these just do everything correct and you will be happy or have a professional do it for you.

Wow!

I've slowly been finding out about NVX products and have been nothing but impressed with them. Perfect for a sound system on a budget!

best box ive owned

I would recommend this box I have two dual voice coil 12" subs in it and it sounds great,

Cheap

The title says it all. Ordered a pair, fed them 700w @ 2ohm, they didn't even last a full week. I didn't expect a 'game changer' when purchasing these but I did expect some form of quality. The money spent was a complete waste and to be honest I took my business elsewhere for my 'less than a week later' sub purchase. I've been a loyal sonic customer for over 5years but this one transaction may have put an end to that. These are NOT worth trying. You're just as well off, if not better, throwing in a pair of low end 2-for-1 kickers

Wow!!! Excellent box

I am now on box number 3 for my subs. This box has brought my love back to my system. Insane how much a box can change it and it looks amazing.

Look/Sound Good

Sturdy construction and is even insulated on the inside. It has good looks and connectors for the speaker wires also. I would purchase this brand again.

Great box with room for small improvements

I put a pair of Alpine Type R's in here and they sounds great! The box came in perfect condition, and on time. One of the first things I noticed was the wire terminal seemed to be pretty low quality, but are mounted very well. The pictures don't show this, but mine came with a logo screwed in on the corner of the blue/front part of the box. The only BIG con is that the port is very rough and sharp. Overall this is a good box and I do not regret putting this hefty chunk of goodness in my trunk.

Great vox

The box is made perfect and go's with my speakers. I would definitely recommend 100%

Awesome sound!

Went well beyond my expectations, great sound and very well built.

Sub hits hard and well made

NVX is impressive when it comes to value and performance! Very happy with this sub and running a 250watt RMS / 500watt max amp this sub preforms!!

Belva BBX212BL (BLUE)

This box is amazing. Pros: It is a very nice box, has very nice terminals on the side of the box, and is very well built and very strong. Cons: It is pretty heavy but that is because it is so strong and well built, and because it has the white stuff lining the inside makes it hard to get the terminals out to wire them.

Great price great product

Nice big box looks nice and great price.Would definantly buy again

Very Unsatisfied

My 12” Memphis subs wouldn’t fit without taking the rubber from around it to sit in the box properly.
Very Ugly looking without the rubber around my speakers. Highly unsatisfied.

This a good box for the price

I love my box it go good with my blue car

NVX NSW122 v2

I really like the value of these subwoofers they sound really good durability wise very well built . They have a really good response plenty of base for what I'm looking for very happy with the product thank you.

It's a cable. It works.

Cables all work and ties keep everything tidy. Plenty of extra length in a Mazda 3. My 5ch amp RMS power draw with volume all the way up should be under 360w (realistically under 250 when not trying to go deaf) so this should be more than sufficient.

Pros:
Cables all sufficiently long for my installation.
Everything included made the install quick and easy.
Only 8ga so the wires aren't super stiff allowing for easy routing.

Cons:
None so far.

Other:
Hopefully never need to test the fuse 60A rating.

great quality and works as designed

Quality kit

Wiring is nice, not too much or too little insulation and the kit contained basically everything needed for the job aside from the hex key tool which would've been a nice little bonus tool to include in there. Would overall recommend

Finally installed it all!

Well I am an old man so I don't crawl under dash boards or climb in trunks like I used to. Months after getting the last of what I needed I finally got some installed myself and paid the guys at work to do the rest (I did the speakers and they did the amps and wiring.)

NVX 6X8s in the doors, NVX 5 1/4s on the deck, 12" N series (dual 2 ohm I set at 4) powered by an NVX mono amp that is 450 watts at 4 ohms. Head unit is a Cerwin Vega with a Cerwin Vega 60X4 @ 4ohms amp.

All I can say is DAMN! you guys hit it out of the park with NVX! I have put complete systems in the wife's car, the kids etc., but never my own. I finally broke down and did it and I am impressed! So if you're rolling down the street and you come on a senior citizen in a Grand Marquis jamming out, give me a wave cause I can't hear ya!

Great value

Did what it was supposed to do.

A great bargain

I was going to get a different amp install kit but this one was 50% off with my purchase so I decided to try it out. The kit comes supplied with everything needed to install most amplifiers. The lengths were sufficient for my install and everything looks to be of great quality. Shipping was extremely quick and well packaged.

It makes installation a breeze. It leaves a clean install.
