Knocks your socks off
This amp has plenty of power. I don't know how much headroom I have to spare because I am not going any louder - no way!
I listen to classic rock (Rush, etc.), and it is nice and clean... and this is with keeping my factory el cheapo head unit in my Hyundai.
I have some hiss when sound is off, and it could be I have the gains set too high. I will be checking that later (because it got too late tonight, and we needed to finish for the day), but I feel quite sure there is no fault with the amp. I am giving this great rating based on having listened for 1 hour so far. As long as the amp holds up for the long haul, it is a great amp for a great price.
John Islas with SonicElectronix was my sales rep, and he was good to work with.

NVX 5 channels amplifier
This is my first car amplifier. It been a great suggestion from a representative seller from Sonic electr. Today I can listeng to my music from a great amplifier that can keep a lot power. I been using it since 3 moths and now I'm more familiar with the ampli and also with my new radio (also get it at Sonic). I have the best of 2 worlds. Finally, I great thanks to Michael, a seller that answer to all my question and gave the best advises to a bigginner as me. I got from Sonic my Pioneer DEH-X9500BHS, my Polk MM speakers and my NVX Amplifier. All that toghter makes a great combination. I went with Sonic because of a such great service. For sure I'll come back in the futur. Carlos from Montreal

I purchased this amp in March '14, but waited a few months before reviewing. This is an excellent amp without question. I have had zero issues with it since day 1. It does not heat up the way my old Alpine amp did, and will only get warm to the touch after hours of use. Highly recommended.

This amp is pretty awesome so far. I wanted to have a so gel amp that I could tuck under my passenger seat on my 2011 Mazdaspeed 3. It fits perfectly, teamed up with the nvx 4 gauge amp kit and the the nvx 1 farad cap. I get minimal power drop at idle and nothing when driving. No lights dimming, nothing. But my sub is numbing and speakers are loud and clear. Love it so far. Highly reccomended.

Small foot print, lots of output , runs cool !
I purchased this amp cause of the great reviews it has. It has a really small foot print. the power ratings where in the range I was after. I play my music pretty loud and have never had any concerns of over heating. The amp runs warm at times The output is very clean and smooth sounding. The only thing I wished it had was maybe a bass boost around45Hz for the front and rear channels. The subwoofer does have bass boost option. I have not tried to use it. I am using the Rockford fasgate 360.3 so I run the the amp with all eq's and boost off. But overall this is a great amp. I have been very impressed by NVX so far.

Best Bang For your Buck!
I was a bit reluctant at first since I never heard of NVX but the Rep at Sonic highly recommended it stating that it was a great product with awesome Sound Quality.
He was right!
To take it further I decided to contact NVX in California and spoke to Richard. I picked his brain regarding the JAD900.5 and he went into all of the details and completely addressed all of my questions and concerns.
He also took the time to advise on the proper setting up and matching the unit to other equipment.
I received it and installed it immediately, tweaked the tuning to it's best and all I can say is WOW!!!!! 279? This amp is "EXTEMELY" well worth every penny and then some!!!!
I have had top brand products before and to be honest they are just extremely Over Rated and way over Priced!
Specs Match top line.
It hits very hard and I don't have the Gain Levels turned all the way up.
It doesn't heat up after being driven for hours straight non stop .
Not a fancy setup Kenwood KDC-X895 Head Unit, Infinity Kappa 692.9i using 6x9 Speaker Baffles filled with sound insulation on Rear Deck Infinity Kappa 6x8 in Doors, MTX Thunder 12" 8000 in 1.7 Non Ported Box. 4 Gauge Power and Ground wires + Monster Speaker wire.
Pro's: Small Size, Doesn't heat up, Clean Looking Unit. Clean Sound Quality I would highly recommend this to anyone!
Thanks Richard and Thank you Sonic Electronix!!!

I was skeptical at first but very glad I bought this amp.
I was looking for a smaller amp to replace my two larger amps that I had from a previous install.
I had use the Massive NX5 last year and had the over heating issue every time I was in my car.
The NVX has yet to have any problems. It gets warm to the touch after a 45 min drive but not flaming hot like some other amps.
I like to play my music loud so I was worried that the 70 watts RMS its rated for would disappoint. I had the exact opposite experience! This amp pushes my CDT speakers with ease.
Also note that you can run your system active just by using the built in crossovers.

Nice amplifier, you should have one
Very nice amplifier, crystal clear sound transformation and small size which could fit in your car anywhere, and light weight to save some gas.
Installation pretty easy, but need to buy other accessories to install, all the lines are pretty, but shipment takes some time. If they are in a whole package will be easy and save customer some time. Thanks.

I purchased this amp to replace a dead channel FLI amp that was DOA and no longer available from sonic. Kinda got pushed into a more expensive amp but they were right. I am pushing 2 pairs of polk db components and a 8" JBL gto sub. WOW!!! Great mid sonic lows and very clean. I have pushed this amp for an hour at moderate to high levels and not even warm to the touch. Not a hint of clip at near unlistenable levels. Best 5 channel amp out there that i have ever heard. I am now a loyal NVX Customer! Thanks Sonic.

WOW ! AWESOME VALUE AWESOME POWER!
My experience with Sonic Electronix has been excellent ! The NVX product line is a fantastic value and the performance rivals products 3 times the cost. The JAD900.5 is the amp you need if you are looking to run your whole car audio system with 1 amplifier. I have been so VERY impressed with the power and performance from an amp with such a small footprint. I have 8 speaker running off the 4 stereo channels and one 12in 4ohm sub from the sub output. This amp has more than enough power and is capable of putting out 1000watts RMS of clean, clear power if you want to max it out. For $299 this amp is a steal of a deal and I could not be happier with my purchase. It has all the features you need in a car audio amp except High level inputs which I did not need. I give this amp 5 stars across the board and you will to. I did my research first and it paid off in spades. JUST BUY IT !
