The DX4 Full Range Digital Amplifier was designed to supply massive amounts of power in small areas.

Compact enough to be placed almost anywhere, this amplifier is perfect for fittings to motorcycle fairings and other spots most amplifiers would be unable to fit into. What this amplifier doesn’t have in size, it makes up for in the production and maintenance of it’s power; this amplifier’s components are attached to a printed circuit board (PCB) that allows it to maintain high efficiency even at low voltages and utilize surge protection features (such as speaker overload, short circuit, and low input voltage protection) which helps it provide unyielding power that maximizes your speakers to their production peak.

With high pass and low pass filter options, this amp is flexible enough to play mids, highs, and lows with unmatched accuracy for an ear opening audio experience.


  • Great power per size ratio packing in 3000w in a very small package
  • Power Rating of 150W x 4 at 4 ohms: 250W x 4 at 2 ohms: 480W x 2 at 4 ohms bridged
  • Can be used in 2, 3, and 4 channel configurations with the channel switch
  • Can be powered up by a signal from the RCA, Offset Voltage from Speaker Inputs, or a 12v remote
  • Small and powerful design so you can power your new equipment with great efficiency and power without taking up much space
  • Integrated low pass and high pass filter to help you get the perfect response you are looking for.
