NVX MVP Micro V Amplifiers

The Micro-V MVP series amplifiers are our smallest amplifiers yet! If we're talking size that is! These amps are almost the size of a deck of cards, measuring in at just 4"W x 5-7/16"L x 1-9/16"H but still pumping out some serious juice! Our new MVP series amps use a cutting edge micro Class-D circuitry to keep the footprint small but the efficiency and output high. These amps are perfect for tight fit installations like in Smart Cars or motorcycles but are perfect for anyone who wants a bangin' system without taking up too much space.

RMS Power Rating:

  • 4 ohms: 50 watts x 4 chan.
  • 2 ohms: 100 watts x 4 chan.
  • Variable low-pass filter (40-400 Hz)
  • Variable high-pass filter (40-400 Hz)
  • Input Sensitivity: 200mV-5V
  • 8 gauge power and ground wiring is required for installation.

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.
