ST-2500.2

High-Power Class AB Amplification Performance

The SoundXtreme ST-2500.2 is a powerful 2-channel Class AB MOSFET amplifier designed to deliver strong and stable audio output for demanding car audio systems. With a maximum output rating of 5000W, it provides substantial headroom for driving subwoofers or full-range speakers with authority and clarity.

Engineered for both 2-ohm and 4-ohm stability, this amplifier ensures flexible system integration while maintaining consistent performance across different speaker configurations.

Precision Sound Control & Crossover Tuning

Equipped with adjustable high-pass and low-pass filters, the ST-2500.2 allows users to fine-tune frequency distribution for optimized system performance. The HPF and LPF controls help eliminate unwanted frequencies, ensuring cleaner sound reproduction and better speaker protection.

Variable gain control and wide input sensitivity range enable precise matching with different head units, while maintaining low distortion and balanced output.

Durable Design & Clean Signal Transmission

Built with chrome-plated RCA inputs and integrated LED indicators, the amplifier provides both durability and clear operational feedback. The signal-to-noise ratio greater than 70dB ensures reduced background noise and improved audio clarity during playback.

Its compact yet heavy-duty chassis is designed to handle heat efficiently, making it suitable for long-duration high-output listening sessions in automotive environments.
