A robust PWM MOSFET power supply ensures stable output, while built-in circuit protections guard against shorts, overloads, and overheating. Tuning your system is a breeze with variable 12dB high-pass and low-pass crossovers, a wide input sensitivity range (200mV–8V), and low total harmonic distortion under 0.05%. Whether you're cruising the highway, riding off-road, or hitting the open water, the PSA4.2500D brings dependable, high-performance sound wherever you go.
