  • Rated Continuous (RMS) Power @ 14.4 V
  • @ 4 Ω 70 W RMS x 4
  • @ 2 Ω 100 W RMS x 4
  • Bridged @ 4Ω 200 W RMS x 2
  • Rated Continuous (RMS) Power @ 12.5 V
  • @ 4 Ω 50 W RMS x 4
  • @ 2 Ω 80 W RMS x 4
  • Bridged @ 4Ω 160 W RMS x 2
  • The JX400/4D employs a highly-efficient Class D design with a robust MOSFET power supply to deliver a strong 100 watts to each of its four channels into 2 ohms (14.4V, 1% THD).
    Use the JX400/4D in combination with our JX500/1D or JX1000/1D monoblocks to build an amazing amplification system at a very affordable price. Or, use the JX400/4D by itself to power two satellites, plus a subwoofer.
    The JX400/4D includes a defeatable 12 dB / octave filter for each channel bank, which can be configured as a low-pass or high-pass filter and offers continuously variable cutoff frequency selection from 50-200 Hz. Dedicated hi-level inputs are included, in addition to conventional low-level RCA inputs, making it easy to integrate with a variety of OEM and aftermarket head units.
