The Alpine Amplifier 5 Channel S2-A55V is part of Alpine’s next-generation S-Series, designed to deliver Hi-Res Audio certified performance across your entire vehicle audio system. This compact 5-channel amplifier combines high-fidelity sound with robust power and advanced tuning features, making it ideal for drivers who want a plug-and-play solution that upgrades every drive with clarity, detail, and impactful bass.

With Hi-Res Audio certification, the Alpine S2-A55V amplifier reproduces music with studio-quality accuracy. It delivers 60W RMS at 2 Ohms to each front and rear speaker while powering a subwoofer with up to 300W RMS. For a 3-channel 2-way system, it can drive a pair of high-performance front speakers with 120W RMS each alongside a 300W RMS subwoofer, creating a balanced soundstage with deep bass, detailed mids, and crisp highs. A variable bass boost on the subwoofer channel lets you fine-tune low frequencies for extra impact.

Advanced features give you precise control over your audio setup. High and low pass filters ensure each speaker and subwoofer receives the optimal frequency range, while the bridgeable subwoofer channel allows flexible system configurations. Optional wired remote control (sold separately) makes it easy to adjust bass levels from the driver’s seat. Supporting both preamp and speaker-level inputs, the Alpine S2-A55V amplifier is compatible with most factory and aftermarket audio systems.

The compact, durable design of this 5 channel amplifier allows installation even in tight spaces. Automatic turn-on detection simplifies setup by eliminating the need for a separate turn-on wire with speaker-level inputs, making it a true plug-and-play solution. This amplifier’s sleek, robust construction ensures long-lasting performance while integrating seamlessly into factory or custom systems.

The Alpine Amplifier 5 Channel S2-A55V is best for drivers who want a high-performance amplifier capable of powering an entire audio setup with clarity and control. Perfect for casual listeners and audio enthusiasts, it delivers deep bass, crisp highs, and a balanced, immersive sound experience.
