Soundstream Digital Pre-Amp amplifiers offer-up an innovative approach to traditional sound processing. DPA amps include a digital signal processing integrated circuit module that opens the door for precise tuning of crossovers & gain settings. Keeping the user in mind, all functions are controlled by top surface mounted keys, needing only a finger press & knob turn. Selected crossover frequencies and gain levels are displayed on top-mounted LCD, showing operating voltage & temperature while at idle. Full-featured pre-amp options, including band-pass & subsonic crossovers, and bass boost make DPA amps a go-to for any enthusiast.

Using an Original or Factory Radio? No Problem, this amplifier is equipped with an Automatic Hi-Level Signal Sensing Turn-On. No need to run a remote wire turn on, this amplifier will detect the signal and turn on and off automatically. (Hi-Level Input only)
