The Alpine S-Series Digital Amplifier Digital design for low space consumption. Compact and powerful: The new digital amplifier circuit allows high output power with small footprint. The S-A32F has a width of only 204mm and a length of 204mm, so it can be installed in virtually any vehicle. Protection against overheating. In addition to Alpine intelligent amplifier technology, the new S series amplifiers feature improved heat dissipation and active protection circuit. This ensures reliable music playback. All connection terminals on one side. The speaker and power cable connections are all on the left side of the amplifier. This allows for a clean and easier installation. The power connections have been designed in such a way that even large cable cross-sections can be properly and securely. Useful Features Low and high-power inputs. The 4 RCA signal inputs accept low and high power signals from the control unit. This allows you to connect the S-A32F directly to your original car stereo (RCA open end connection cables sold separately). High-pass / low-pass filter. With this filter you can adjust the separation 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 (available separately) to the S-A32F (only channel 3+4 bridged when using a subwoofer).

Review: Just such a nice and clean sound... perfect for a long road trip... mine is in 3 weeks from now - This amp sounds amazing. Absolutely amazing. Crutchfield told people that you couldn't have a 40A amplifier as that was too much draw on the battery. Their limit was 30A, but others who install radios say this is fine... just don't go over 100A... that's too much draw. So I haven't experienced any issues with the car since installing it but I have this turned up now to 18 out of 40 and it sounds amazing in the car and loud enough to pack a punch. Size is nice and compact and it was easy for me to install with secure connections using a hex wrench. So I'm very happy with this and will finish the mount this week. This one replaced a Sony 15A amplifier which worked fine, but this one is clearly just night and day between the two.

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 ### ⭐⭐⭐⭐⭐ Just such a nice and clean sound... perfect for a long road trip... mine is in 3 weeks from now *by L***N on 7 February 2026* This amp sounds amazing.
