The Alpine S-Series Sound Components
Three new S-Series amplifiers join the S-Series family, known for reliable performance and value-oriented products. All three S-Series amps (mono, 4-channel and 5-channel) contain technology currently implemented in R and X-Series models. The S-Series amps feature attractive prices and are designed to perform perfectly with the existing S-Series speakers.
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.
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).
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).
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.
