Alpine introduces the all-new S-Series amplifiers – a perfect match to the S-Series speakers. These amps have an excellent Watts-per-Euro ratio in the Class-D category, feature a very high heat resistance and won’t shut down due to overheating. They also feature excellent sound quality in their price range.
The S-Series amplifiers are available in mono, 4-channel and 5-channel configuration.
All Digital Design
Compact and Powerful: the new digital amplification circuit allows high power output while keeping a small footprint. The S-A55V measures just 286mm in width x 204mm in length for easy installation in virtually any vehicle.
Along with Alpine’s new intelligent amplifier platform, the new S-Series amplifiers feature an improved heat sink and protection circuit design that eliminates thermal shut-down, for dependable music playback.
One-sided Cable Terminals
The speaker and power cable terminals are conveniently located on the left side of the amplifier to allow a clean installation. The power cable terminals accept heavy gauge cables.
Low/High-Power Speaker Signal Inputs
The 5-Channel RCA speaker signal inputs accept low and high-power signals. This makes it easy to connect the S-A55V directly to your original car stereo, regardless of your head unit’s power output (RCA connectors with open cable leads are available separatly).
Control Your Subwoofer
You can connect the RUX-KNOB2 remote bass knod (optional available at extra cost) to the S-A55V to controll the subwoofer level straight from your dash (applicable only for channel 5 for subwoofer usage).
High-Pass / Low-Pass Filter
With this filter switch you can assign the amplification channel (pair) to be used for door speakers or a subwoofer. You can then adjust the cut-off frequency for more precise tuning.
