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 next generation S-Series S2-A120M mono subwoofer amplifier makes it a lot easier to get great bass in your vehicle, delivering up to 1200 Watts RMS power @ 2 Ohms. This massive power output allows to even run multiple subs from a single amplifier. A variable bass boost allows you to dial in some extra punch 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.
A built-in low-pass filter puts you in command of the frequency spectrum that reaches your sub. The amp includes pre-amp- 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.
