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.

good product

I have no complaints this product is great i would recommend This to anyone looking for easy Setup .

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!

Great seller

I advise!! Fast shipping!! I received my amp perfect!!

Simply Awesome

When I saw this amp and read up on it I had to have it. It's a lot of bang for the buck. Setup is scary simple. The digital circuitry and class D design is clean and second to none. I have this paired with a JBL P1224 in a ported box and it is much louder than I expected. Very nice.

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.

JBL MS A5001

This Amp is beautifully designed, easy to use and set up! I have it running one 10" JL W1 in a small sealed enclosure in my 2014 4runner. Power is clean and plenty of it. I highly recommend it for its design, flexibility, and clean power!

Serious power, I love the amp for the value

I paired this with two 10" GTO JBL 528 subs wired in parallel, 4 ohm, and it hits so freaking hard, my jeep bounces! Seriously, this is a great amp for the cost. I also own JL Audio and can't tell the difference.

Nice Amplifier!

I am using this for a pair of Pioneer TS-W260S4 subwoofers and a Kenwood Excelon 998 in a 2003 F-150.

This was a huge improvement over the OEM installation, and I am really enjoying the punch that these deliver!

The installation and setup of the amplifier went well enough without any major issues.

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

great little amp

The shipping was fast and packaged appropriately. The only minor inssue I ran into during installation was the remote input. The input had a 1.5 hex instead of 2.5, so the supplied Allen wrench wouldn't fit. I would suggest reading the book a couple of times b4 setup. I have it pushing a Fi Audio X10 in a 1.3 ported enclosure tuned at 33hz. It sounds better than when I had the kicker zx750.1 pushing it. I'll have to update this review once I have it for awhile to give opinion on durability.

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.

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.

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.

Awesome features

Purchased this amp for the features. Upon arrival, it did not work. I hooked up my Kicker and completely forgot about it. Sonic has a great warranty, so I sent it back- even after the warranty had expired. They gave me another even, so I hooked it up and mounted it on the box, as my box has an amp rack. I blew the screen. It still works great but I can't change anything on the amp as I cant see what I am doing without the digital display. Shame on me for that one!

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.

jbl ms-a5001

Awesome amp for the money. Pushing 2 rockford fosgate p1. Sounds amazing.

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

great amp

This amp is great easy to use and set up nothin bad to say about it

pundits in the back of a 2013 legacy

I've found this amp is very well put together. The digital face is a nice touch. But don't think you can get this and not know how to work it.. you still need to know how to tune an amp.. this one just makes it easy.

By devin on April 18, 2015 Verified purchase

Magnifique

I love this Amp. very simple to setup with the digital screen et great sound quality with its DSP treatment.
I love JBL for the sound quality.
I attached this amp; with a pair of JBL CS1214 and they are playing very clean.

I LOVE IT!!

I purchased this amplifier to power two RF P3 10inch, dual 2 ohm subs. It does an excellent job at this but I love it soooo much, I'm getting one more and upgrading to two 12inch T1 dual 4 ohm subs. This amp is extremely easy to set up considering the amount technology packed into it. There are almost all usable crossover frequencies available, lo pass and hi pass. Good job Harmon Kardon on an excellent product!!! I've used it for two weeks now so my 5 star durability is a bit subjective...

Versatile!

Separate input/ouput level adjustments, digital crossover (no guessing!), subsonic filter with variable frequency & slope, defeatable crossover (on hpf & lpf), variable slope on lpf (same as hpf), automatic turn-on, underrated power, wireless bass remote... What's not to like?? Perhaps the only things I could find is not being 1 ohm stable for those that need it & some had issues with the wireless bass remote staying connected, but other than that this is probably the most versatile mono amp on the market and especially at this discounted price level. These will be missed when they're completely gone from the market.

Bargain

this amp puts out over 700 rms @ 2 ohms...make sure your woofer can handle that much!!!

Great Easy Features!

Powerful Amp for its size. It is really simple to use and has great features! Where was this 10 years ago? The reproduction is great, sound quality and did I mention the features! You can't go wrong with this amp for its price, power and features. It's not a SPL monster but a middle of the road every day type amp. As with any JBL product...its loud and clear!

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.

Best value

I recommend this little amp because is so powerful and easy to install any were and the setup so fast and tucking about the sound is great but don't take it from me get one and then you can just for you self A1 little amp

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
My unboxing vid here https://youtu.be/DRb1p4pWm-4

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.

By Stu on October 21, 2020 Verified purchase

BUMPS!

All I have to say about these NVX subwoofers is GET THEM NOW! Seriously. They're so nicely designed and sounds so good with that nice tight bass! Highly recommended!

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.

great sub

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

truly amazing

I've owned many amps by orion hcca jl audio memphis audio kicker and even a JBL gt series back in the 90's. First I am impressed with how compact this amp is. The digital read out and being able to perfectly dial the hz in and signal is something I've never seen before and truly comes threw when dialing in your preferred sound. I have it hooked up at 4ohms to 2 12 gto single 4ohm subs in vented box. I can not believe the sound 250w per sub this amp produces. Just incredible. This is by far one of the amps I've ever owned. Top notch two thumbs up I can't imagine it getting any louder and only have it hooked up with a factory radio. But when I get a aftermarket head unit and run it at 2 ohm it will probably be the best overall system I ever owned JBl out did themselves here. For a amp this impressive under 200 you'll be a fool to even look at anything else. Hats off Harmon. Thanks sonic electronix for such a great deal.

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.

By rocky on April 7, 2018 Verified purchase

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.

Awesome product!!! Great price!!

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!!!

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.

Wow! These NVX Push hard in my Buick century

I am using a 1100watt Hilfonics Amp and it sounds amazingly clean and hits super hard! The best upgrade yet for A very good price! Heads are turning for sure! They match well with my Polk Audio Component set u

They are Worth every cent! I’ve recommended them to a friend Because He loves how my system sounds. Clear!

Works great with my two JBL 1214's

I put this amplifier in my Camaro Powering two twelve inch subs. It has more than enough power to fill the car, but don't expect to be able to hear your music two blocks away. It is easy to set up and has a very useful suite of features. Overall excellent quality and good price. It doesn't look flashy, but I don't need it to. Would definitely recommend for use with JBL's 1400 watt subs

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.

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.

By Arthur on October 11, 2016 Verified purchase

I wanted some decent bass...

I got some pretty awesome bass and a ton more power than I was expecting. Have had 0 issues, and have maxxed this thing out for 2-3 hour drives. It never stutters, it always hits hard, and remains clear. Definitely glad I went with this. If you're considering a 500 watt amp, this is it for the money.

What a deal!!

I was considering purchasing this amp for the full $399.99 retail price several months ago. I waited and SonicElectronix had it for (cheaper) so I jumped on it immediately and I'm glad I did. This is a compact amp that will fit just about anywhere you would want to install it. It features some great tuning features and a lot of power. If anything the power is underrated on this unit rather than overstated like so many amps on the market today. The high-level input adapters are appreciated since I installed it off the rear speakers. The remote turn-on feature is nice because I don't have a dedicated remote turn-on line from my factory radio.

I did have an issue with a loose connection internally in the amp. I sent it back to SonicElectronix and am awaiting the replacement.

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.

UNIQUE FLASHY AND NICE BUT..........

its nice to have endless options, real world power over manufacturer, nice looks, small, stays cold, but ive had a few and emailed harmon they are know for memory issues digital setting don't always stay. also the soft start on it doesn't work well. still has a pop other amps don't in my car. also in high level it takes an eternity to turn on after radios on. sound is decent thanks to options. basically i think there are better amps if you can deal without the nice flashy looks. my kicker cx600.1 sounds 1000 time better turns on instantly has no pops and put out same power.

Awesome amp, HUGE BANG for the buck !!

This was the first JBL amp I have ever bought. After a few months of "thinking" about it and reading several reviews, I decided to take the plunge. I am NOT in ANY way disappointed. Both the power of the amp, and sound quality (if you tune it the way they recommend) are both impressive. Installation was easy, tuning was easy to do, although I felt the step by step instructions were mildly vague in a couple of areas, taken a moment to look things over they were easy enough to figure out. I do intend to buy at least one more of these and a 5 channel JBL amp for my Suburban. (once I convince my wife that is...lol) I would ABSOLUTELY recommend this amp...no doubts at all. Also, Sonic, as always, shipped fast and free....Thanks guys!

A lot of power in a small package!!!

First off it should be noted that I am a HUGE car stereo fanatic and usually only deal with HIGH end and competition level equipment like JL Audio, Rockford Fosgate, Creacendo Audio, DC Audio, Sundown Audio etc. etc and so naturally I was skeptical about this amp at first but when I saw the price drop on Sonic and based on other reviews along with Sonics own dyno test of the amp Im glad I purchased it. Its very small but packs a huge punch. I currently have it installed in a 2014 Infiniti Q50 Hybrid with 2 12" JL Audio 12TW1 Subwoofers in a sealed JL enclosure @ 2ohms and this little amp really hits hard. I am really impressed with the features of the amp and being able to change the curves on the fly is a plus. The fact that the amp has both high and low level inputs means I dont need to put a high-to-low, just run the feed from the factory sub right into the JBL and its done. The calibration CD it comes with makes level matching a sinch. The only negative this product gets is the fact that it DOESNT come with the wireless bass knob... And you can forget about finding it online too.... I searched for 2 weeks and finally found it on Amazon UK but at a hefty price tag (80$). It was worth it though as this remote is wireless which means NO WIRES TO RUN. It paired easily with the amp and really makes a difference as it doesnt asjust the gain like alot of other remotes but actually changes the sub curve... Did I meantion its wireless?? I would definately recommend this amp to anyone looking for some big bass in a small package without the big price tag. JBL is a name you can trust. By the way the amo is rated at 500 watts but youre easily getting over 900 watts @ 2ohms. Im happy and i plan on getting the 4 channel when I get the chance.

JBL ms-a5001

I'm using this little amp in a Jeep Wrangler jk 4 door. It fits nicely under the passenger seat for a clean look. I'm using it to push a single 12w6v2 in a slot ported box. It matches well with the sub. It has just enough power to push it to its limit. I'm really happy with this purchase. Great price, and fast shipping.

Great Product

Easy to use and setup. Hi/Low Level converter wasn't needed for installation. Clean power and does a great job powering 12". The wireless bass knob is neat feature, but a bit quirky.

clean insane settings just awesome onf of the niceset easiet amps yuoull ever own!!!!!!!!!!!!!

Works but not for long

Bought this amp, I found it very difficult to set up, even following the instructions... it worked well and after about 8 months the screen stopped displaying. I didn’t pay attention to it as it still worked well. Traded in my car and I was unable to set it up without the screen working. Paperweight now.

Awesome severely under rated amp.

Small footprint, easy to setup, lots of settings, and capable of around 300RMS over rated pushing a 2 ohm load. The 4-channel version is notorious for issues, but this mono version seems solidly built.

Great amp..clean..stays cool 2 ohm..Harmon Kardon..design..WARNING..digital input level locks in after one try..so get it right..if you change head unit..it will have to have the same inpedense output..read the book..use the CD..

Quality Product

Wow! About all I can say about my recent experiences with Sonic Electronix and JBL. I am running 2 JBL GT5-15's 2 MS A5001 JBL monoblock amps, one on each sub. Signal coming off of the stock head unit in a 2000 Toy Camry. The amps are barely idling and the subs are still tight as the day I bought them. Taking it easy on them until they break in, but judging by the quality of the speaker and it taking some time to break in, I can tell this system is going to last. The bass response of the subs is tight and powerful the amps are clean and efficient. Once again Sonic and JBL exceed expected standards in quality product product cost and always great customer service. Thank you Sonic JBL

Great Product and Great Service

I searched for months for the perfect amp. I was looking for sound quality and value. This amp is a ridiculous value. Forget about alpine. They're great amps but they don't touch the value here. This thing is super sophisticated and it's rated at 500 watts but it puts out closer to 850 clean watts. I don't have a super duty charging system so I needed something efficient and this is definitely efficient. JBL far exceeded my expectations. Especially for the price. By the way it's CEA rated.

love it

this is not a amp that will blow out a window... but wow does this thing sound great... its very small and the sq is incredible for the price... it is not the loudest amp ive had but its the smallest and best sounding

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.

Just as good as my other Class D sub amps..

This amplifier is such a little gem. Its ultra compact and puts out just as much power as my JL Audio amps, and in my opinion.. sound better! Its stronger.. hits harder and you can dial in the frequencies very easily. Great buy!

WOW

THIS THING WAS AWESOME INSANE AMOUNT OF SETTINGS CLEAN EASY TO USE SO BEAUTIFUL TO LOOK AT WISH IT STILL WAS MADE

Great product

Great price little dated but still performs rather nicely🤔on a pair of dated 10 inch CVs!

Easy to Use Crossover Points but thats all.

I've owned this amp for two years, I recently upgraded to a hifonics brx 1600.1D.

Pros: Easy to set the Gain
Digital Crossover Points
Compact Size

Cons: hi-level inputs known to fail
Wireless bass knobs never paired correctly

Failed after two years, with an error code of 04! JBL and Sonic Support have no idea what this code means and with no resolve I moved to a Hifonics BRX 1600.1D -- Problem Solved

Twice as nice.

I recently purchased 2 of the JBL MS-A5001 digitally processed amps. I am running one each on JBL GR5-15" subs in two sealed single enclosures. The bass is so deep warm rich tight and clean from the processing in these amps. Still pushing everything with a stock head unit in a 2000 TOY Camry. Plenty of output room left on the Amps. Run them for hours and they are hardly warm let alone get hot. Sonic once again provides quality products with the best prices.

Great JBL MS-5001 Amp & Great Service from Sonic Electronix

first I want to point out that Sonic Electronic made unfortunate problem I had worth having because of there customer service! A few months back I bought a JBL MS-5001 amp and the very first time I turned it on after the install the amp made some RCA input noises? so I called Sonic for a RA (return authorization) number and boxed up the Amp and had it ready to ship, Well I went on a two week vacation and when I came home and seen the box still where i left it I realized that I forgot to take the Amp to UPS before I left, I was worried that it would now have to be repaired and not just replaced since now it is past the 30 day return policy, I felt that Sonic went out of there way to help me by going a head and sending me a brand new one anyway..... The JBL MS-5001 is even better than I had hoped it would be running a single 4 ohm DVC 12" Sub at 2 ohms and does not even get warm after pounding that 12 all day.... very happy ...
