Entry-level sound just got elevated with the S2-A55V 5-Channel Amplifier. Its sleek redesign houses an Alpine Class D Amplifier Circuit and is now certified for Hi-Res Audio.

Hi-res Audio: The Next-Gen Alpine S-Series S2-A55V 5-Channel Amplifier is Hi-Res Audio Certified and able to reproduce up to 40kHz frequency response. This ultra-wide bandwidth coupled with the elevated S-Series design brings out a new benchmark for entry-level performance and price.

Flexible Application: The Next-Gen S-Series Amplifiers now feature a new selectable remote turn-on circuit, a three-position switch that ensures the amplifier turns on and off at the proper times. This design is crucial with newer, in-vehicle technology and allows for proper integration with any factory or aftermarket system.

Easy Control Access: The amplifier was intentionally designed with sound controls located on the side panels, instead of the top panel, making it easier to access gain and crossover controls when installed under the Jeep seat or in a shallow-depth locations.  Removable end caps were added to cover the side controls and connections, providing a clean, sleek finish to the amplifier.
