Alpine S-Series: Affordable Hi-Fi Performance

The S2-A36F is part of Alpine's next-generation S-Series amplifier range, offering a sleek redesign and upgraded features over its predecessors at an accessible price point.

Each channel delivers 60W RMS at 4 ohms or 90W RMS at 2 ohms, driving your front and rear speakers with clean, detailed sound. In a 3-channel setup, the bridged rear channels output 180W RMS to a subwoofer while the front channels independently drive a pair of speakers at 60W RMS each. A variable mid-bass EQ on the rear channels lets you dial in extra low-frequency impact. You can also add the optional Alpine RUX-KNOB2 remote control to adjust rear channel levels from your front seat.

High- and low-pass filters give you control over the frequencies reaching your speakers and subwoofer. Both RCA preamp and speaker-level inputs are included, making the S2-A36F compatible with factory and aftermarket head units alike. With speaker-level inputs, the amp detects the incoming signal and powers on automatically — no separate turn-on wire needed.

Hi-Res Audio Certified

The S2-A36F is Hi-Res Audio certified, reproducing frequencies up to 40kHz for precise, detailed playback that goes well beyond the standard 20kHz ceiling.

Flexible Application

A three-position selectable remote turn-on circuit ensures the amplifier powers on and off at the correct times. This makes it straightforward to integrate with modern factory or aftermarket systems, including those with complex vehicle electronics.

Easy Control Access

Gain and crossover controls are positioned on the side panels rather than the top, making them accessible when the amp is fitted under a seat or in a shallow-depth location. Removable end-caps cover the controls and connections when not in use, keeping the finish clean.

Mid-Bass EQ

The variable mid-bass EQ circuit lets you increase low-frequency impact on the rear channels as needed, making the S2-A36F a strong choice for systems where bass punch and dynamics are a priority.
