JAFive 5-Channel Class-D Amplifier

All-in-One Powerhouse for Full-System Control

The JAFive is a full-range 5-channel Class-D amplifier built for clean, efficient system-wide control in a single chassis.
With four full-range outputs and a dedicated subwoofer channel, it’s ideal for powering an entire system — front, rear, and sub.
High-level (speaker wire) and low-level (RCA) inputs ensure easy integration with factory or aftermarket head units.
Adjustable crossovers, variable bass boost, and wide-range gain control give installers and enthusiasts flexible tuning
without sacrificing clarity, control, or power.

Why it’s robust

  • System-wide performance: 85W x4 + 310W x1 @ 4Ω, or 135W x4 + 495W x1 @ 2Ω (1% THD+N).
  • Dynamic headroom: Up to 1175W max dynamic power (10% THD+N).
  • Precision tuning: Selectable high-pass/low-pass filters (50–250 Hz), subsonic filter (30 Hz/24 dB), and variable bass boost @ 45 Hz (0–6 dB).
  • Clean signal path: 86 dBA S/N (CH1–4) / 88 dBA (Sub) and <0.12% / <0.20% THD+N at 1W for low-noise, high-impact output.
  • Ready for any system: Works with RCA and speaker-level inputs; 2/4-ohm stereo stable for flexible installations.
  • Installer focused: Variable gain (300 mV–6 V), 4 AWG power/ground and 12 AWG speaker wire recommendations,
    dual 40A fuses, and a compact chassis: 1.99” x 6.53” x 13.07” (H x D x W).
