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-A32F measures just 204mm in width x 204mm in length for easy installation in virtually any vehicle.

Thermal Protection
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.

Low/High-Power Speaker Signal Inputs
The 4-Channel RCA speaker signal inputs accept low and high-power signals. This makes it easy to connect the S-A32F directly to your original car stereo, regardless of your head unit’s power output (RCA connectors with open cable leads are available separatly).

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.

Control Your Subwoofer
You can connect the RUX-KNOB2 remote bass knod (optional available) to the S-A32F to controll the subwoofer level straight from your dash (applicable for channel 3+4 in bridged mode for subwoofer usage).
