4-Channel Class D Amplifier

The Alpine S2-A36F is a next-generation 4-channel Class D amplifier from the S-Series, engineered to deliver a significant upgrade to your vehicle's audio system without breaking the bank. It is Hi-Res Audio Certified, with a frequency response extending up to 40kHz, allowing for reproduction of precise audio details and emotional depth. This amplifier offers flexible application, providing 60W RMS per channel into 4 ohms or 90W RMS per channel into 2 ohms for your front and rear speakers. It can also be bridged to deliver 180W RMS into 4 ohms for a subwoofer. Features include integrated high-pass and low-pass filters (50-400 Hz), a variable Mid-Bass EQ for enhancing low frequencies, and pre-amp and speaker-level inputs for compatibility with most factory or aftermarket systems. The auto turn-on function activates the amplifier when it detects an incoming signal, eliminating the need for a separate turn-on wire. Installation is made easier with all connections located on one side and a compact design for simple mounting. Sound controls are conveniently placed on the side panels, accessible even when installed in tight spaces, with removable end caps for a clean finish. The amplifier also includes a selectable remote turn-on circuit with a three-position switch for proper integration with modern vehicle electronics.
