NVX JAD Amplifiers

The NVX commitment to quality, performance, and usability is perhaps best exemplified in the JAD series amplifiers. The faithful audio reproduction is complemented by the striking minimalist design of the ultra-compact chassis. With a footprint roughly the size of a sheet of printer paper and well under 2” thick, the JAD amplifiers are an installer’s dream. They easily stash under the seat of a sedan, behind the seat of a truck, in the small trunk of a roadster, or an infinite number of other mounting possibilities. The amps are remarkably tough inside and out, from the strong aluminum housing to the 3-way protection circuit with LED indicators.

To reduce the size of the chassis, the NVX engineering team employed advanced Class D circuitry. In addition to its compact size, this circuit provides the benefit of incredible efficiency, making the most out of the limited power available from your car’s electrical system. Since more of the battery power is turned into real amp power, this design generates minimal heat. A revolutionary chip designed by International Rectifier (affectionately known as the IR Chip) eliminates high-frequency interference sometimes associated with older Class D circuits. The result of this design is a pristine audio signal with the requisite power to breathe new life into your sound system.

JAD amplifiers are currently available in 3 models, each of which can be used independently or complementary to each other, depending on your system layout and goals. The JAD1200.1 is the only monoblock in the series, but with an RMS power output ranging from 500 to 1200 watts it is incredibly flexible, and can be used to achieve nearly any level of bass desired. The amp is 1 ohm stable for maximum compatibility and power output, and features both low-pass and subsonic high-pass filters to finely tune your subwoofer. For convenience and quick adjustability, the JAD1200.1 comes complete with a remote bass level control knob.

CEA-2006 Compliant: The CEA-2006 Standard is an official testing and measurement method for amplifiers established by the Consumer Electronics Association. In order to standardize the power ratings of mobile amplifiers, the CEA-2006 compliancy ratings where established to inform the customer that they are getting the wattage that they paid for. In defining this standard, CEA tests and rates the ”performance of amplifiers designed for use in mobile (vehicle) applications”. This statement found on the CEA website continues to define the types of amplifiers that they will test. It is applicable for single channel and multi channel amplifiers that rely on the vehicle’s primary electrical system and have a power output of greater than 5 watts. When an amplifier is tested, CEA uses the following method to ensure that the ratings are consistent.

For RMS Power Output of Amplifiers:

  • Tested at 14.4 Volts
  • 4-ohm Impedance load
  • <1% THD (Total Harmonic Distortion)

When looking for an amplifier, it is important to see if the manufacturer has received a CEA-2006 compliancy for the amplifier. If so, then the ratings can be trusted at the advertised wattage. If they are not CEA certified, it could mean one of two things. First, the manufacturer has not submitted the amp for testing and it may or may not perform as advertised. Second, the specifications of the amp are not considered to be CEA-2006 compliant.

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

  1. Very Impressed!  star rating

    Posted by Kendal Harker on 25th Apr 2016

    This is the best sounding amp I have ever used. It was easy to self install, the connections are common standard and straight forward. It started right up out of the box and the default setting were all ready done assuming 6 channel input and standard 5 channel HPF/LFP setup.

    Now I need to get another one of these for my car.

  2. Excellent!  star rating

    After much shopping around for a 5Ch amp, I located this one. I do not regret this purchase at all. The amp is small and compact which TONS of punch. It is pushing my four interior speakers and one 10" sub perfectly, very well balanced and extremely loud. Also used NVX power wire to run and the wire is great too. I will continue to purchase NVX products.
