Great sounding amp! True power output.

This amp is great! It is affordable and performs very well. It sounds great through the JBL 960C component speakers and NVX 6x9s in the back. The only complaint I have is the size. This amp is long. It barely fit mounted on the rear of my 60/40 split rear seat but that's not the fault of the amp. Class A/B amps just run bigger and with this much power delivered, it has to be that big to dissipate the heat. It has an internal fan on the bottom. Make sure to mount it in a way that it has clearance for good air flow/intake to keep it cool.

Sweet

This amp is pretty big so make sure you do your measurements. It fits under my backseat of a 95 Jeep Grand Cherokee and the Amp is killer. It
has a fan on the bottom that I didn’t see anywhere In the description. What a huge difference because there is no air under that backseat and this thing hasn’t overheated. I recommend this amp my stereo has never sounded so good.

Solid product!

I like that NVX has good quality amps and also very pocket friendly. I don't have to spend a ton of money to have a great sounding system and if I accidentally blow anything again I didn't spend that much on it so no biggie. I will buy more NVX products.

Great AB Power

They do rated and have a good sound. I was between this or a deafbonce class AB but this had a bit more power and I love to have overhead. Can't go wrong at 130. Also they send 3 replacement screws, alan keys, and hardware WITH RUBBER STANDOFFS CAUSE THERE IS A FAN ON THE BOTTOM! Just amazing.

Now I'm thinking If I should get another one just cause there such a good deal

Great quality sound!

This is a very large amp, is does take about 100A to power this thing! I set it up the moment is was delivered, took very little time to set up the levels and off I went enjoying crystal clear audio from my infinity speakers! I’d highly recommend NVX amps for anyone that enjoys their music
