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 wired remote lets you control bass level from the driver's seat.
