Alpine S2-A120M S-Series 1200W Mono Amplifier
If you’re hunting for hard-hitting bass and clean, consistent power, the Alpine S2-A120M is your golden ticket. This mono subwoofer amplifier isn’t just about being loud—it’s about delivering deep, distortion-free bass that feels like a punch to the chest (in the best way). From clean design to raw output, this amp brings everything your subwoofers have been begging for.
Built to Bring the Boom
At the heart of the Alpine S2-A120M is Alpine’s next-gen Class D amplifier circuit. Think of it like the brain and muscle behind the madness—built to push serious wattage while keeping things cool and efficient. This beast pumps out 1200 watts at 1 ohm and 2 ohm, and 600 watts at 4 ohm, making it perfect for slamming a pair of subs or powering a single one to full capacity.
No fluff, no gimmicks—just power where it matters most.
Ready for Real Bass? This Amp Can Handle It
Powering dual 10" or 12" Alpine S-Series subwoofers? No problem. The S2-A120M was practically made for it. It’s like handing your subs a megaphone—they suddenly become louder, stronger, and clearer. That deep bassline you used to barely hear? Now it rumbles through your seats and stays crisp all the way through.
Side-Panel Controls = Zero Hassle
Ever tried adjusting amp settings buried in the back of your trunk? It’s a pain. That’s why Alpine put the controls on the side. Gain, crossovers, and everything else you need are easy to reach—even in tight installs like under seats or in compact trunk spaces. And with included removable end caps, the setup stays looking sleek and finished, no wires hanging out like spaghetti.
Selectable Crossovers for Tailored Tuning
Let’s talk sound control. Built-in selectable and adjustable crossovers give you the power to fine-tune your low-end response. Want tighter, punchier bass? No problem. Prefer a warmer rumble? You’ve got options. It’s like being handed the remote to your own personal subwoofer show—you’re the one calling the shots.
Tough Tech, Sleek Looks
The Alpine S2-A120M doesn’t just perform—it looks the part too. Its compact build (just over 13” wide and under 9 lbs) makes it ideal for space-conscious setups, but don’t let the size fool you. With a rugged, modern design and sturdy build, this amp is made to ride along for the long haul. It even includes a birth certificate (aka "birth sheet") that verifies the actual power output right from the factory—so no guesswork on what it’s truly pushing.
Quiet When It Should Be, Loud When You Want It
This amp doesn’t just deliver volume—it delivers clarity. With a signal-to-noise ratio over 85dB, it stays whisper-quiet when your tracks do. No hiss, no hum, just smooth transitions and clean sound reproduction. And with a frequency response range from 20Hz to 400Hz, it digs deep into the low-end spectrum and brings out the richness in every note.
Smarter Integration for Modern Systems
Got a factory stereo or a newer head unit? Alpine’s got you covered. The S2-A120M includes a selectable remote turn-on circuit with a three-position switch—meaning it turns on and off exactly when it should, even with the latest vehicle electronics. No guesswork, no annoying pops or delays—just seamless operation every time.
Why Settle for Less Bass Than You Deserve?
The Alpine S2-A120M isn’t just another amp. It’s a performance-driven, sound-sculpting, bass-loving machine that gives your subwoofers the power they need to shine. Whether you're upgrading your factory system or building something from scratch, this amp is the key to unlocking real power and true low-end precision. If your music matters, this is the amp to make it hit harder, cleaner, and deeper.
