The Alpine S-Series Digital Amplifier Digital design for low space consumption Compact and powerful: The new digital amplifier circuit allows high output power in a small footprint. The S-A32F has a width of only 204 mm and a length of 204 mm, so it can be installed in virtually any vehicle. Protection against overheating In addition to Alpine's intelligent amplifier technology, the new S Series amplifiers feature improved heat dissipation and an active protection circuit. This ensures reliable music playback All connection terminals on one side The speaker and power cable connections are all located on the left side of the amplifier. This allows for a clean and easier installation. The power connections have been designed so that even large cable cross-sections can be properly and firmly accommodated. Useful features Low and high-power inputs The 4 RCA signal inputs accept low and high power signals from the ECU. This allows you to connect the S-A32F directly to your original car stereo (RCA connection cables with open ends are sold separately). High pass / low-pass filter With this filter, you can adjust the cut-off frequencies, e.g. for the door speakers or a subwoofer. Subwoofer control For direct control of the subwoofer from the dashboard, you can connect the Alpine RUX-KNOB remote control button (optional available) to the S-A32F (only channel 3+4 bridged when using a subwoofer).

You could also run both pairs on 2 channels and bridge the other 2 to run a sub. **Q: Will this run my r series r-s65.2 and r-s69c.2 speakers or should i have bought the r-series amp (r-a60f)?** A: I don't know the specs of your speakers, but this amp puts out 55watts @ 4ohms and 80watts @ 2ohms. BTW, that's per channel. I have the S-Series speakers which match this amp. They sound great paired together. But, I know the R-Series can handle more wattage. **Q: Will this amp push 4 pioneer 6x9’s** A: 4 Pioneer 6x9s is very vague. You need to, at minimum, know the specs of your speakers. This amp is rated as 55watts/channel @ 4ohms and 80watts/channel @ 2ohms. **Q: Is this class A/B or class D?** A: Alpine has all the specs listed on their website. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exactly what you need *by C***N on 25 June 2026* Best amp in its class, at a reasonable price this amp makes no noise when cranked up, its compact.
