Power for your whole system

Alpine’s S-Series S-A55V amplifier makes it easier than ever to get great sound in your vehicle. This 5-channel powerhouse can put out 40 watts RMS each to four full-range speakers and up to 300 watts RMS to a subwoofer, and still fit into the tight spaces you find in many cars and trucks these days. You can also use this versatile amp in 3-channel mode, driving a pair of high-performance speakers with 120 watts each, while still sending 300 watts to a sub.

Technology that keeps you on the air

Enhanced Shutdown Performance technology rolls back the output a bit when the amp threatens to overheat from playing at its limits too long. Instead of shutting down completely, it continues playing your music until it cools enough to return to full power.

Convenient features

High- and low-pass filters put you in command of the frequencies that reach your speakers and subs, while a bass boost lets you apply some extra low-end punch. The amp includes preamp- and speaker-level inputs, so you can install it in almost any vehicle, even one with a factory radio. If you’re using the speaker-level inputs, the amp senses an incoming signal and turns itself on, eliminating the need to run a turn-on wire back to your vehicle’s receiver or fuse box. An optional RUX-KNOB.2 wired remote lets you control bass level from the driver’s seat.

The Better Choice in Performance Value

Perfect for beginners and enthusiasts alike, the S-Series amplifiers have the technology to improve your music experience yet are still friendly on your wallet. Used in conjunction with our advanced S-Series speakers and subwoofers, they create a complete sound system that takes your in-vehicle music experience to the next level.

Small but Mighty

The S-Series amplifiers are designed to fit anywhere. The S-A55V 5-Channel model measures at 11.25” W x 8” H x 2.25” D and can be mounted under seats or behind panels. It proves to be the all-in-one solution for a multi-amp system, so you can enjoy big power output in a limited installation space.

Reliable Performance

The S-Series amplifiers contain technology that was previously only available in our premium line up of amplifiers, the R- and X-Series models. The S-Series models are based on Alpine’s intelligent amplifier platform that ensures superior sound reproduction and precision imaging. With an improved heat sink, and protection circuit design that eliminates thermal shut-down, your music will keep playing no matter where your drive takes you.
