PRODUCT OVERVIEW
Entry-level sound just got elevated with the S2-A120M Mono Amplifier. Its sleek design houses an Alpine Class D Amplifier Circuit with 1200W of powerful bass performance.
PRODUCT FEATURES
Unparalled Power - Alpine’s S-Series S2-A120M 1200W Mono Amplifier is the perfect solution for unparalleled power and performance on a budget. With a power output of 1200W at a 1ohm or 2ohm drive, this mono amp is capable of driving even the most demanding subwoofers, delivering clean and distortion-free bass for a wide range of applications.
Simplified Installation – The amplifier was intentionally designed with sound controls located on the side panels, instead of the top panel, making it easier to access gain and crossover controls when installed under vehicle seats or in shallow-depth locations. Removable end caps were added to cover the side controls and connections, providing a clean, sleek finish to the amplifier.

PRODUCT OVERVIEW
The next generation of sound performance is here with the new R-Series subwoofers featuring a larger motor structure for more accurate and authoritative bass.
New Motor Structure – The new R-Series subwoofers now feature larger, double-stacked magnets that contribute more motor force for deeper bass and tighter bass control compared to the previous generation.
Oversized Dust Cap – The new hybrid poly ceramic composite dust cap ensures rigidity while also providing incredible internal damping (vibration absorption) to smooth out the bass response and reproduce tight bass.
Increased Accuracy – Alpine’s High Amplitude Multi-Roll (HAMR) Surround Technology allows the cone to efficiently move air while staying cool resulting in incredible accuracy from the subwoofer.
