Our take on 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.
