The New 2023 S-Series Amplifiers
Entry-level sound just got elevated with the S2-A36F 4-Channel Amplifier. Its sleek redesign houses an Alpine Class-D Amplifier circuit and is now certified for Hi-Res Audio.


Hi-Res Audio Certified
The Next-Gen Alpine S-Series S2-A36F 4-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 vehicle seats or in shallow-depth locations. Removable end-caps were added to cover the side controls and connections, providing a clean, sleek finish to the amplifier.
Mid-Bass EQ
With its new and unique variable Mid-Bass EQ Circuit, the S2-A36F allows you to dial in the mid-bass impact as desired, making it an ideal choice for those seeking a more dynamic and powerful audio experience.

Made for S-Series Speakers & Subs
The S-Series amplifiers are designed to perfectly match the Alpine S-Series speaker and subwoofer line for perfect system building. S-Series components are designed to for customers that want to build a great sounding system without breaking the bank, for a fun and great sounding experience including Hi-Res Audio capabilities.
