About this product
Built for clean, reliable bass amplification, the JAOne brings efficient Class-D performance in a compact mono-block layout. Whether you’re pushing a single subwoofer or looking for tight, distortion-free low end, this amp delivers. It supports both high-level (speaker wire) and low-level (RCA) inputs for easy integration with a variety of systems. With a selectable low-pass filter, variable bass boost, and bridgeable power, the JAOne gives you the flexibility to dial in serious low-frequency impact without taking up unnecessary space. Why it’s robust Real power you can use: 300W RMS @ 4Ω, 500W RMS @ 2Ω, or 1000W RMS @ 1Ω (1% THD+N). Strong dynamic headroom: Up to 1300W max dynamic power (10% THD+N). Precision tuning: Selectable low-pass filter (50–150 Hz), plus variable bass boost @ 45 Hz (0–6 dB). Clean signal path: 90 dBA S/N (1 W ref) and <0.12% THD+N at 1 W for clean, efficient output. Flexible integration: Works with high-level and RCA inputs; 1Ω stable for subwoofer applications. Installer friendly: Variable gain (200 mV–6 V), 8 AWG power/ground and 12 AWG speaker wire recommendations, 30A x 3 fuses, and a compact 2.01” x 5.67” x 8.25” (H x D x W) footprint. Peak Power This amp can reach a max dynamic power of 1525 Watts for a powerful listening experience! Compact Design This amp’s compact design makes for easy, non-intrusive, and convenient installation! Efficient Power Output The JAOne Amp has a class D design for improved longevity and high efficiency power output.
