Soundmax SX-LX5125.5D – 5-channel Class D amplifier with power for the entire system

Soundmax SX-LX5125.5D is a compact and powerful Class D 5-channel amplifier developed for those who want to run both speakers and a subwoofer from a single amplifier. With four channels for front speakers and a dedicated bass channel, you get a complete solution with high efficiency and easy installation.

The amplifier delivers 4x100W RMS + 350W RMS at 4 Ohm, providing plenty of power to drive midranges, coaxial speakers, and a subwoofer at the same time. At 2 Ohm, the output increases to an impressive 4x160W + 650W, making the SX-LX5125.5D capable of handling far more demanding systems than many traditional 5-channel amplifiers.

The efficient Class D design provides high output with low heat generation and excellent efficiency, making the amplifier stable even during extended listening sessions. The wide frequency range of 10–45,000 Hz contributes to clear reproduction across the entire range, from deep bass to detailed highs.

With low distortion of only 0.15% and a signal-to-noise ratio of 90 dB, the SX-LX5125.5D delivers clean and controlled sound even under heavier load. The wide input sensitivity range of 250mV–8V also makes it easy to pair the amplifier with both factory head units and aftermarket systems.

Despite its high output, the amplifier features a compact size of only 280 × 120 × 52 mm, making it easy to install even in smaller spaces.

Soundmax SX-LX5125.5D is a perfect choice for those looking for a compact all-in-one solution with enough power to run an entire audio system from a single amplifier.
