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
