All the NVX products I've bought seem to be top quality so that's why I bought 4 NVX amps.

Does the job with a small footprint but big clean power. Still new but no issues.
Suggestions for improvements... With all these "clone" amps such as PPI, Hertz, Arc in this price-point it'd be difficult to improve the performance. That said, I can see the value in a few items especially for small-footprint amps. Values I like include 1. all wiring on one side with easier access from overhead while installed. 2. easier access to mounting holes without a shroud around it. 3. differential-balanced inputs. 4. Go to sleeves in a 1/0 hole for big wire connections instead of a butt out plug going into a 4ga hole for 12v/ground terminals. Truly just nitpicky stuff, which makes you see what separates a $250 amp from a $500 amp. Awesome amps as is and good looking clean appearance.
Now I know these things would be a completely different design given these are sourced boards similar in layout to many seen. So they're just improvement suggestions should the design of the board allow.
But as is, with both NVX JAD amps I have, I say overall BRAVO! They sound great, appear to be very well engineered and constructed, and if they hold up well, it was a good purchase and I'm an NVX fan. They're as big a hit as their X-Series speakers which I hope NVX continues for a long time.

I have this amp paired up with DLS U6i speakers and a set of Pioneer tweeters taken from a Pioneer component TS C1720C. The Pioneer mid bass driver was replaced with a pair of Kicker Comp VT6s- 61/2. I have always been a fan of JL amps and with this set up I have 2 - the other is the JL XD 600 for bass. Originally, the amp powering mids with this set up was an old JL 300/4 amp. The old amp after 15 yrs went in to protection mode and influenced by Sonic consumer reviewers I decided to save money and make a change. The goal was that if the experiment did not work out I would get the old JL amp fixed. As it turned out, there was no need to go back to the JL amp. The NVX had a very compatible sound in terms of clarity but was much louder. To compensate for the higher and brighter mids the gain from the little JL XD amp (powering a 15 inch RE sub) had to be raised. The end result was that the imaging in the car was broadened. Indeed, a fuller spectrum of frequencies was achieved -as well a broader stage. Also noteworthy, is that the NVX is smaller than the JL. Thus, everything said about this amp is true and I also strongly recommend this product. It is definitely a high end amp at a very good price.

Ordered the NVX JAD 800.4 due to the reviews I read. I was hoping for something powerful and compact. As soon as I got the 800.4 I was surprised how small it actually is, and the RMS rating is 125W but actual RMS output per channel is 140W!!! Tones of power for any speakers you want!!
Only downfall, no pass-thru to hook up the JAD 1200.1 Im going to be getting soon.
NVX JAD800.4 is HIGHLY recommended for any needs: great price, small size, and super powerful!

found this helpful.Very Happy so Far
I purchased the JAD800.4 along with a JAD1200.1 to power my Infinity Kappa speakers and MB Quart subs. My first choice was the Infinity Kappa Five amp, but I had problems with two of them and was given a store credit. Second time around I decided to go with two amps (4/1channel) hoping for better performance / reliability.
I read a lot of mixed reviews on Class D amplifiers. Many people think that A/B has better sound quality, while others prefer the small footprint, high power / low heat output of Class D. Being an engineer I reviewed the specs and was very impressed with the signal to noise as well as the THD compared to Class A/B.
NVX is a relatively new brand so I turned to Google and found several good reviews. I was looking at the Polk amps and NVX seems to be very similar, with the controls panels and specs being almost identical (and NVX was in stock).
Out of the box the amps had a solid feel and clean look. They have a soft-start feature that powers them up a few seconds after they get power. This gives you time to start your engine without drawing any current. Very nice.
The sound quality is excellent - better than other A/B amps I had in the past. More than enough power - I haven't even cranked them all the way up yet and don't think I'll ever have to.
I have a second MB Quart 10 RLP on back order because with one sub I was getting distortion before I could feel the bass. It turns out that the Infinity Kappa Five amp was the weak link. The JAD 1200.1 pushes one sub very well.
The only negative I have to say about these amps is that the adjustment dials take a philips screwdriver, and they do not have an arrow or line showing you what it is set to. This made it a little inconvenient to tweak the crossover points.

found this helpful.Really Impressed
I was looking for an amp to power my hertz hsk165 components and my hertz ecx690 6x9s. I had the JL Audio 400/4 powering them but i wanted them alittle louder but didnt wanna lose sound quality. I was gonna get the Polk PA 4000.4 but Sonic was outta stock so this NVX amp was the next best option. I was worried because I've never heard of NVX but man im impressed. The Quality is just as good if not better than my JL amp. So far I love this amp. Im gonna make a youtube vid in bought a month with my whole system... its gonna be the Chamelleon Impala

found this helpful.NVX D Class Four Channel
This amp is insanely small but really puts out the power. It doesn't have a big draw on it and is lightweight and have a white led on it which is pretty cool. Wish it had a copy/mirror switch that would allow to copy two of the channels. Love that it comes with a wire reducer block, really came in handy. It was kind of cool that the set screws were Phillips instead of Allen wrench, they are convenient but easier to strip. The gains have clicks instead of just being smooth so it is a bit easier to match gains. Overall a very good amp.
