Product Highlights:

Efficient and Versatile

The NVX NBA401 is categorized as a Class A/B amplifier. This class of amplifiers combine the high efficiency of a class A amplifier and lower distortion found in class B amplifiers. The class AB amplifier acts more similarly to a class A amplifier by biasing both transistors so they become active when the signal is close to zero. As the signal excursion increases into a larger waveform, only one transistor remains active, a primary function found in class B amplifiers. These features combined with the MOSFET transistor allow the NBA401 to be one of the most efficient amplifiers on the market. The NBA401 also features three-way protection circuitry which protects against thermal, overload, and speaker shortages. This configuration increases the longevity of both the amplifier and entire speaker system.

Assured Quality

The NVX NBA401 is constructed to meet the highest quality standards. While other amplifiers on the market often inflate their specifications, the NBA401 is tested using the Consumer Electronics Association’s ratings test. This means that all specifications listed for the NBA401 are accurate for peace-of-mind. The NBA401 also uses threeway protection circuitry, protecting not only the amplifier, but the entire sound system from thermal, overload, and speaker shortages. This helps increase the longevity of the sound system as a whole.

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.

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.
