90W x 4 @ 2Ω

Alpine S2-Series 90-Watt x 4-Channel Power Amplifier @ 2-Ohm or 60-Watt x 4-Channel @ 4-Ohm 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. 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. The amplifier was intentionally designed with sound controls located onthe 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. 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.
