Soundstream RSM1-4000D – Reserve Series Micro Monoblock Amplifier

Built for Performance, Designed for Tight Spaces

The Soundstream RSM1-4000D is part of the Reserve Series—a dealer-exclusive line of high-performance amplifiers engineered for maximum efficiency in compact installations. Don’t be deceived by its size. This micro footprint Class-D monoblock amplifier is a powerhouse, pushing out 4000 watts of RMS performance that rivals much larger competitors in both sound quality and raw output.

Compact Class-D Power with Reserve Micro Technology

The Reserve Micro amp line represents the cutting edge in amplifier design, blending Class-D full-range amplification with Soundstream’s RSM power management system. These high-efficiency mono amps deliver potent output while drawing minimal current, making them ideal for modern vehicles with limited charging system capacity.

The RSM1-4000D was created to support everything from subwoofer-driven systems to setups with component speakers, thanks to its adaptable high-pass and low-pass crossover filters, bass boost (0–12 dB @ 45Hz), and subsonic filter (10–50Hz). The included wired bass knob gives on-the-fly control right from the driver’s seat.

Feature-Packed for Seamless Installations

For users retaining their OEM or factory stereo systems, this amplifier includes Automatic Hi-Level Signal Sensing Turn-On—no remote wire necessary. The low-level RCA and speaker-level input options ensure compatibility with nearly any setup.
