Looking to purchase one and it was the first time seeing a mono input/output for the rcas. This video is phenomenal information wise and I absolutely love turning to him for information when I need. New follow
Ty for this review. Exactly what I need. I basically got suckered into buying a JL 10w3 from a local shop. This does decent power into a 4 ohm load, so I should get acceptable performance out of the sub. For the price I wish I would have gotten a different sub, but I think in the end I will be satisfied.
Glad I could help.
Great video Justin! I like your style of amp dyno’s and I appreciate the shout out.
Always glad to shout out the O.G.
Gonna get one for 2 skar ix 10 d2s perfect pair for them was looking for a small amp with a clip light thanks for the video
Great video Justin
Thanks Bobby!
Great video!!
I've been waiting for one of these amps to hit the dyno.
Preformed amazing and the circuit board is so small🤣
I was impressed!
Do me a solid and use the code DIYAUDIO10 at NVX.com
You can get you a dac that can output 2v without much money. A desktop dac can do this easily and there are PLENTY of options out there.
👍
Loving the NVX stuff. Waiting for them to restock the VCW 12".
I'm eager to get my hands on some of their subwoofers.
@@DIYAudioGuy Call me crazy but the VCW sounds %90%95 as good as a Rockford T1. At a fraction of the cost.
Just discovered your channel. Good stuff. Thx. Maybe we can see an install some day?

Awesome video Justin 👊🏼 It’s so cool seeing little amps like that putting out big power but I’m still not sold on the Brazilian style full bridge amplifiers. They’re inexpensive watts per dollar wise but what good is it if it’s blown? They need to start making them reliable. Too many problems wit those amps in my opinion.
That's fair.
Full bridge has been around forever, and is very reliable. The problem with "Brazilian" style full bridge, was that they were using boards that were to thin, and it could not stay stable under loads and carry the voltage. JL Audio, Rockford, Alpine and many other companies have utilized full bridge over the years. Taramps used thinner boards in the HD lines, and it was absolutely a problem. We have about 30 full bridge samples in hand, and have been fully tested over the past year, from the same build house used by CT, Sundown and a few others. We made changes to the amplifiers, with faster switching fets, changed up the low pass filters to 40hz and some other small changes. We had one amp fail, out of the 30 or so we have tested. It failed, running at. 7 ohm in a daily build,, after 4 months. This amp he tested here in this video, is an 800.1 board. The build house, has updated the boards a bit since the SFB models, they built. Keep them at 1 ohm, keep the voltage at 11-15 volts, and there isn't much problems to have. Just from our experience. Great video btw. I am now a subscriber!!
Love these little NVX amps I've had one mounted under my seat for years you might be able to get more bump for the $ elsewhere but for the form factor and build quality NVX there is no match.
This was my first experience with the X series. I have used on of their four channel amps in the past.
@@DIYAudioGuy I guess technically I have a NVX VAD10001 a different series but either way I have been very impressed with all of nvx's products.
For a cheap clean source it may be a good idea to use a dac/headphone amp combo. The fiio E10k and the schiit audio fulla 4 would both be great options.
My plan is to upgrade to a touch-screen head unit in my truck and then use my old reliable alpine on the test bench.
@@DIYAudioGuy that'll definitely work too
I have a fiio too. I forget which model, but mine with samsung droid will output ldac. I think it costs about $80? I cant remember
Love NVX products
I ran one of their four channel lamps for a while. I was very happy with it.
I’d love to see their pre made fibreglass boxes (vehicle specific) for build quality and actual box volume as I’m sure many will swap out the subwoofer for a more powerful sub.
👍
Having two SIA3500's running the subs in my car I can tell you the only difference is the bass knobs. The sundowns have these nice metal knobs that look like little amps themselves. The only issue I have with them is they go into protect pretty easy. If input voltage is too high... protect. If you turn the gain up a bit... protect. I like to think these amps are built for more efficient bass builds. Putting them on big inefficient subs takes a little too much out of them.
Hey dude! I was so excited to see the video on your channel of that Buick rolling under its own power.
@@DIYAudioGuy It surprised me too!
I have the NVX VAD1000.1 and I love it. But I wish someone would do a dyno run on it. I can’t help but feel that it maybe lacking when wide open. But to be fair that could be many other factors.
I will need to upgrade my test bench before I can do that. This is about as big as I can go before I run out of juice.
70 amp fuses are pretty common if you look for them...mini ANL can be found in increments of 5 amps...so 75 amps are also around..
Cool, thanks
@@DIYAudioGuy Yeah would be a bummer if 80 ampere would be too big of a fuse...But i was impressed with the power that little amp produced and really like your content..
Did you do a video on your resistor load bank? I thought you did.
I have not, I've definitely thought about doing that.
Since it just has a input/output do I need to use a male to female y connector?
That looks like a mirror image of the soundstream TXP1.3500 which puts out quite a bit more power.
Yep, Brazilian style full bridge.
@@DIYAudioGuy I have the soundstream in my Jeep build because of extremely limited space for components. I was just able to put the txp under the rear seat to drive a pair of Skar 12” shallow mounts in a 2cu/ft box. I will say the amp is powerful but dumps noise in the system. It doesn’t have anywhere near enough caps in the supply side so it causes a high-pitched feedback into the system. I’ve tried different power wires, different ground points, different signal wires run different ways. The decider was I dropped the Skar 1200 amp in and it had zero noise, which narrowed the problem down to the specific soundstream amp. Unfortunately the Skar amp doesn’t fit so the same amp is back in and I have a bunch of ground loop isolators installed that mostly get rid of the noise.
If you're interested, since I have the skar as a spare (albeit it'd be laying on the rear floor) I'd be happy to send the soundstream your way so you can test and compare it to the NVX. Be interesting to see whether or not it actually puts out anywhere near what it says it does compared to the visually identical NVX.
@@whodat90 I appreciate the generous offer, but I am good.
Try an NVX line output with bass restoration on ur setup. Ull get 9.5 volt output
I have one, it is cool technology. But, because it adds in extra frequencies it would not be a good choice for the amp dyno. ua-cam.com/video/Fa1sQOu0erQ/v-deo.html
Can you recommend some shallow mount subs for underseat boxes? I want 2 subs around 300-400rms

Did the clip light on the amp work too? Clip light should be automatic, just like a car’s “check engine light.”👍🏼👍🏼
It was perfect, just did not get it on camera.
They put a boat on the board and take it off. Then put it back on and say “no bass boost” then take it off and say “bass boost” all for boat!!??? Yay!!!!
Make sure you use the code diyaudio10 for a discount at nvx.com.
The code isn’t working right now, just a heads up.
@@zackmattox9792 did you try it on the NVX website or did you try it on Sonic electronics?
@@zackmattox9792 did I spell it right? Sometimes I have a tendency to get letters swapped?
I’m on NVX and it’s spelled right I believe, diyaudio15. I’ve also tried it in caps.
@@zackmattox9792 They recently updated the website. That might be the issue. Sorry that it is not working.
I might be showing my age (46) but I remember when $1/Watt was a deal then the standard... our pay was less, power costed more... with no sacrifice comes n reward ;)
I remember those days.
Nvx has best deal on 1/0 gauge ofc wire right now too 10ft $39.99 before the discount code
I will have to check that out!
I have this amp. I fused it at 60a. Is that too small? I thought the formula was (700/.8)/14.4
That will probably work just fine for music in a daily driver.
KnuKonceptz Kolossus Fleks Kable 8 Gauge can handle 60 amps up to max 20 feet. At 3 feet, from distribution block to amp, it can handle up to 100 amps.
That is good wire.
What about 6"?
@@theejoeylee Their chart doesn't go that low so I have no idea. The real question should be "Why not use 4ga after 100". For a 6" run especially, you're talking barely anything. If already running 4ga from the battery back to dist., I can't imagine not having 6" left over.
@@marcuslinton310 My amp won't fit 4awg ( razor 2500D)
@@theejoeylee It only has 50amps worth of fusing, 8ga is more then enough.
How can I get help from you to design a box for my car?
diysubwoofer.blogspot.com/2021/05/custom-subwoofer-enclosure-designs.html
The reason it is called impedance rise is because that is what it is. The reason you can't call it box rise is because it happens when the driver isn't in a box.
You can tell that it is impedance rise because of the way it is.
I'd pay the extra $35 and get the Skar 1200.1. The internals of this amp just seems really sketch, almost like that less is less type of feeling. Great SMALLamp but there are better options IMO. Cheers!
If I were you, I would check out the NVX website, after you throw on that discount code a bigger amp will start to look real cost effective.
I would not buy a skar RP amp for anything terribly in efficient at 1 ohm and will not make near this kind of power on a active load . Plus for $35 more you could get a 3k Brazilian clone or a recoil 1200.1 that's a better sounding amp with a clip light.
Yes and No it looks like lees because of the Brazilian style full range compare to the Skar Chinese Corean clone design
@@DIYAudioGuy I attempted the discount code and it didn't seem to work. I copy and pasted the info. Either way great video!!
@@MOBAudioUSA Hope I can get that fixed today or tomorrow.
This or Skar RP-1200.1D ?
bit.ly/3QH7MfO The discount code is only giving 10% at the moment.
but the test never showed 1ohm with music would have been over 700w i would assume
Absolutely.
@@DIYAudioGuy could this amp really be putting out 700w if it never draws 70 amps i notice with a 60 amp fuse it never blows alil weird
@@jaygee6983 Yes
I only ask because I was told that you want to take the total wattage and divide it by 10 which would be 70. Seems like it's working great with a 60 amp fuse
@@jaygee6983 your calculations are correct. But fuses are rated for current draw in a given amount of time. So if you're not popping the 60 amp fuse when playing full tilt then everything should be just fine.
same full range amp that so many companies use including sundown audio
Also the 15% code didn't work for me
Thanks for letting me know. NVX updated their website recently, I have reached out to them and hope to get it fixed today.
I just heard back from NVX, it should be working now!
How does this amp sound?
It sounded just fine to me, I didn't hear any noise or interference. In the video when I'm doing the live music test you can hear it play. I ran it full range into the subwoofer.
@@DIYAudioGuy ok yeah seems like a nice one. Nvx is one of thsoe sleeper brands i feel like
@@almetej29 most house brands are.
All these amps are pretty much the same coming out of the same buildhouse out if China. They just put different badges on them.
Yes, they might use different components, but the board layout is the same. After you use the discount code (diyaudio10) I don't think you will find a better price on this one.
Those amp internals look a little low on the quality. I know it's a cheap amp, just sayin'.
It looks like every other full bridge amp on the market.
Another full bridge clone..
