Massive bass power

Alpine's Next Generation S-Series S2-A120M mono subwoofer amplifier makes it a lot easier to get great bass in your ride, delivering up to 1200 watts RMS power to your sub. A variable bass boost allows you to dial in some extra kick and impact for more low-frequency enjoyment. You can even add an optional wired remote to control the level of bass from your front seat.

More convenient features

A low-pass filter puts you in command of the frequency spectrum that reaches your sub. 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.
