The Next-Generation Alpine S-Series S2-A36F 4-Channel Amplifier sets a new standard for affordable, high-fidelity sound. Hi-Res Audio Certified and capable of reproducing frequencies up to 40kHz, it delivers incredible detail, clarity, and precision for true studio-quality playback. Combined with Alpine’s refined S-Series design, this amplifier redefines what entry-level performance can achieve—powerful, clean, and perfectly balanced audio at an unbeatable value.
The Next-Gen S-Series Amplifiers introduce a new selectable remote turn-on circuit with a three-position switch, ensuring the amplifier powers on and off precisely when it should. This intelligent design is essential for today’s advanced vehicle electronics, allowing seamless integration with both factory and aftermarket systems for a hassle-free, reliable setup.


The amplifier’s side-mounted sound controls offer convenient access to gain and crossover adjustments, especially when installed in tight or under-seat spaces. To maintain a refined look, removable end caps conceal the side controls and connections, giving the amplifier a clean, sleek, and professional finish that complements any vehicle interior.
