Alpine S2-A55V 5-Channel Digital Amplifier New Series-S

The 5-channel S2-A55V amplifier of the S Series is ideal for those who desire a complete solution for their car audio system. This amplifier delivers 60 Watts RMS at 2 Ohm for each of the front and rear speakers, offering high-fidelity, uncontaminated and powerful sound. At the same time, it can power a subwoofer up to 300 Watts RMS, combining the Hi-Res Audio quality of the 4 channels with the extra power of the channel dedicated to the bass. This configuration allows you to enjoy every musical detail, from powerful beats to emotional nuances, with surprising clarity.

For those who desire a 3-channel and 2-way configuration, the S2-A55V offers the possibility to drive a pair of high-performance front speakers with 120 Watts RMS each, as well as power a 300 Watt subwoofer. The variable bass boost on the subwoofer channel allows you to add greater impact to the low frequencies, while an optional wired remote control allows you to conveniently control the bass level from the front seat.

The amplifier is equipped with high-pass and low-pass filters, which allow you to manage the frequency spectrum directed to the speakers and subwoofers, thus optimizing sound quality based on personal preferences. The high-level inputs facilitate the installation of the amplifier in almost all vehicles, including those with factory radios. Furthermore, the amplifier automatically detects the input signal and turns on by itself, eliminating the need for a separate power cable.
