High-fidelity Signal

Alpine's Next Generation S-Series S2-A36F 4-channel amplifier delivers 60 watts RMS of pristine high-fidelity signal to each of your car's front and rear speakers, adding sweet, clear sound to your ride. The amp's extended high-frequency response brings your music to life, with its precise details and emotional power clearly revealed.

RMS From the Bridged Rear Channels

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.

Optional Wired Remote

You can even add an optional wired remote 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 seperate turn-on wire to the receiver or fuse box.

  • Hooked up my rear and front door speakers running at 4 ohms into the amp. This tiny amp is pushing the speakers easily without any fuzzy sound. Much power from a Class D amplifier!
