Soundstream PSA4.2500D

Built to perform wherever the road, trail, or water takes you, the Soundstream PSA4.2500D is a rugged, high-powered amplifier engineered for the toughest environments. Designed specifically for powersport, marine, and motorcycle applications, this compact powerhouse delivers clean, reliable performance with up to 2,500 watts of peak output. Featuring an IP66 waterproof rating and military-grade PCB construction, the PSA4.2500D is ready for harsh conditions — from high-humidity boat decks to dusty backtrails.

It supports full-range operation at 2-ohm stereo or 4-ohm bridged, giving you flexible power for multiple speaker configurations. 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.
