NEW MODEL

The next generation of Alpine S-Series amplifiers are designed to take your car audio experience to the next level without breaking the bank. With a sleek new redesign and upgraded features from their predecessors, these amplifiers offer exceptional performance and power on an affordable budget.

The S-Series S2-A36F 4-channel amplifier delivers 60 Watts RMS @4 Ohms or 90 Watts RMS @2 Ohms of pristine high-fidelity signal to each of your car's front and rear speakers, adding sweet, clear sound to your vehicle.

The amp brings your music to life being Hi-Res Audio certified, with its precise details and emotional power clearly revealed with a frequency response up to 40kHz. For a 3-channel 2-way system, you could also use the amp to drive a pair of front speakers with 60 Watts RMS each, while powering a subwoofer with 180 Watts RMS from the bridged rear channels. A variable mid-bass boost on those rear channels allows you to dial in some extra kick and impact to your system's low-frequency sound. You can even add the optional wired remote RUX-KNOB2 to control the level of the rear channels from your front seat.

High- and low-pass filters put you in command of the frequency spectrum that reaches your speakers and subs. The amp includes preamp- and speaker-level inputs, so you can install it in almost any vehicle, even one with a factory radio. When using the speaker-level inputs, the amp can sense the incoming signal and turn itself on, eliminating the need to run a separate turn-on wire to the receiver or fuse box.
