Upgrade your entire vehicle audio system with the Alpine S2-A55V S Series 5-channel Class D amplifier. Designed to power four speakers plus a subwoofer from a single amplifier, the S2-A55V delivers a clean, efficient solution for building a complete aftermarket sound system.

The S2-A55V combines Alpine's Class D amplifier technology with Hi-Res Audio certification and a frequency response extending up to 40kHz. It delivers 40 watts RMS x 4 plus 200 watts RMS x 1 at 4 ohms, or 60 watts RMS x 4 plus 300 watts RMS x 1 at 2 ohms, giving you the flexibility to match a wide range of speakers and subwoofers.

For systems requiring additional power to the main speakers, the four full-range channels can also be bridged to produce 120 watts RMS x 2 at 4 ohms. Built-in adjustable crossovers allow you to properly divide frequencies between your speakers and subwoofer, while the bass EQ provides up to 12dB of boost at 50Hz.

The S2-A55V also features high-level speaker inputs with automatic turn-on, making it suitable for integration with many factory audio systems. Three selectable turn-on modes provide additional flexibility when connecting to modern factory or aftermarket head units.

With controls and connections positioned on the side panels, the amplifier is designed for easier access when installed under a seat or in another tight location. Removable terminal covers provide a clean, finished appearance after installation.
