The Ground Zero GZRA 1.2500D Radioactive series monoblock car amplifier operates in Class D and delivers 750 W RMS at 4 Ω, 1,400 W RMS at 2 Ω and 2,200 W RMS at 1 Ω. Link Mode allows two amplifiers to be digitally connected, delivering 6,000 W at 2 Ω. The MOSFET power supply is paired with adjustable Lowpass and Subsonic filters, bass boost and phase shift.
The input sensitivity is adjustable, while the indicator light shows operating and protection status. Protection features cover thermal overload and short circuits. RMS power is based on the CEA-2006-A standard (14.4 V, 1% THD).
