The GZHA MINI ONE-K is a compact powerhouse from Ground Zero’s Hydrogen Series, engineered to deliver serious low-frequency performance in tight spaces. This Class D mono amplifier pumps out up to 1000W RMS @ 1 ohm, with a link mode option pushing up to 2000W RMS @ 2 ohms when paired with a second unit.
Equipped with variable subsonic and low-pass filters, adjustable bass boost, phase control, and a wired remote level controller, the MINI ONE-K offers flexible tuning for daily drivers and SPL builds alike. Its high-level input with auto turn-on makes it ideal for OEM integration, while short circuit, thermal, and overload protection ensure reliable performance at any volume.
With a footprint of just 135 x 52 x 322 mm, the MINI ONE-K is built for big bass in stealthy spaces—efficient, refined, and ready to deliver.
