Alpine S2-A55V 5-Channel Class D Amplifier

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 S-Series S2-A55V 5-channel amplifier delivers 60 Watts RMS @ 2 Ohms of pristine high-fidelity signal to each of your car's front and rear speakers while powering a subwoofer with up to 300 Watts RMS at the same time. The amp's combination of Hi-Res Audio capabilities in its 4-channel section and extra bass power from the sub channel brings your music to life, with all the precise details, pounding beats, and emotional power clearly revealed. For a 3-channel 2-way system, you could also use the amp to drive a pair of front high-performance speakers with 120 Watts RMS each, while powering a subwoofer with 300 Watts. A variable bass boost on the sub channel allows you to dial in some extra kick and impact to your system's low-frequency sound. You can even add an optional wired remote to control the level of bass from your front seat.

High- and low-pass filters put you in command of the frequency spectrum that reaches your speakers and subs. 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.

Alpine S-Series amplifiers are available in two mono, a 4-channel and a 5-channel configuration.
