About the Alpine S2-A36F S-Series 4-Channel Amplifier

The Alpine S2-A36F is a Class D 4-channel amplifier rated at 180 watts RMS total (45W per channel) and certified for Hi-Res Audio up to 40kHz. It stands out with a two-sided terminal layout for easier wiring, built-in selectable crossovers, and a variable mid-bass EQ. It suits budget-minded listeners who want clean, flexible power for a full system without breaking the bank. Compared to rivals, it offers Hi-Res certification and Alpine's S-Series build quality at an entry-level level, though its power output is modest for driving high-end components.

Questions and answers

Is the Alpine S2-A36F powerful enough to drive component speakers?
With 45 watts RMS per channel, it can drive most factory and entry-level aftermarket speakers well. For high-power components, you may want a more powerful amplifier.
What is the difference between the S2-A36F and the previous S-A36F?
The S2-A36F adds Hi-Res Audio certification (up to 40kHz), a redesigned chassis, and a two-sided terminal layout for easier installation. Power output remains similar.
Does the S2-A36F come with a remote bass knob?
No, the remote bass knob is sold separately. The amplifier is compatible with Alpine's optional RUX-KNOB.2 remote bass knob.
Can I bridge the S2-A36F to power a subwoofer?
Yes, the amplifier is bridgeable. Bridging two channels combines their power to drive a subwoofer or a single speaker with more output.
What is included in the box with the S2-A36F?
The box includes the amplifier, mounting hardware, a fuse, and an owner's manual. Speaker-level and power cables are not included.
