S-Series 5-channel Power Amplifier - RMS Power Ratings 4 x 60W + 1 x 300W @ 2 Ohms S2-A55V 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. The New 2023 S-Series Amplifiers Entry-level sound just got elevated with the S2-A55V 5-Channel Amplifier. Its sleek redesign houses an Alpine Class-D amplifier circuit and is now certified for Hi-Res Audio. Hi-Res Audio Certified The Next-Gen Alpine S-Series S2-A55V 5-Channel Amplifier is Hi-Res Audio certified and able to reproduce up to 40kHz frequency response. This ultra-wide bandwidth coupled with the elevated S-Series design brings out a new benchmark for entry-level performance and price. Flexible Application The Next-Gen S-Series amplifiers now feature a new selectable remote turn-on circuit, a three-position switch that ensures the amplifier turns on and off at the proper times. This design is crucial with newer, in-vehicle technology and allows for proper integration with any factory or aftermarket system. Easy Control Access 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. Power a Full System With its versatile 5-channel design, the S2-A55V Amplifier is the perfect solution to power your sound system all in a single chassis. This amplifier delivers crisp and clear audio to up to four speakers plus an additional subwoofer to give your system a complete audio upgrade.
