E-6004D Class-D 4-Channel Amplifier

Built upon on our tried and true technologies platform, the E-Series amplifiers are an Evolution of grace, power and performance.
At its core the E Series amplifiers are built with our signature CRD footprint utilizing every aspect of the SMT-PCB’s creating a significantly smaller amplifier that produces amazing sound and superior performance compared to amplifiers twice their size.
Our Full Range Class D architecture gets a performance boost with our New Suspended Air-Core Heat sink. This new heat sink offers 360 degrees of constant cooling directivity. A radical new approach of advanced cooling compared to conventional formats.
The E-Series amplifiers incorporate future proof technologies like Stop/Start ready, that allow the amplifier to remain powered during the Stop/Start cycle at low voltages without damaging the amplifier.
Loaded with a fully backlit XFIRE logo and a complement of crossover and channel configurations coupled with exceptional signal to noise ratios the E-Series amplifiers stand head and shoulders above the crowd.


  • Ultra efficient 4-channel fullrange Class-D topology design with 5 volt inputs and 2 ohm stability
  • Extensive customization controls like HP/LP/BP crossovers make it easy to design the perfect soundstage
