Soundstream ST4.1000D Stealth Series 1000W Max Power 4-Channel Full Range Class-D Car Amplifier

Soundstream ST4.1000D

The ST4.1000D uses the latest in Class D amplifier technology, once considered “dirty power” due to its high-efficiency nature. However, modern Class D amplifiers have evolved, offering stable performance while maintaining maximum efficiency and low power tolerance. The ST4.1000D is designed to provide clean power that rivals traditional full-range amplifiers, while requiring minimal power consumption. This makes it perfect for car audio systems, motorcycles, boats, and off-road vehicles where space and efficiency are crucial.

Despite its small size, the ST4.1000D delivers a substantial 1000W peak power output and stable RMS power for your audio setup. Whether you’re powering multiple speakers or a subwoofer, this amplifier has you covered. Its ultra-micro footprint allows for easy installation even in tight spaces without compromising on sound quality.

The Class D design ensures high power efficiency and prevents excessive heat build-up, allowing you to run the amplifier continuously without worrying about overheating. Even after hours of high-volume playback, the ST4.1000D remains cool and efficient, making it the ideal choice for long road trips or extended listening sessions.
