Review: Perfect for midrange smaller setups - Alpine has always been my all-time favorite audio equipment! I added this amp to my 10.1 inch android auto head unit in standard cab, 1st gen tacoma. Mounted 6.5 infinity reference separates with baffle, into stock door holes. I have custom sub box with a mid grade 10" rockford fosgate behind driver seat and console. ABSOLUTELY AMAZING !! The sound is crystal clear and bass hit nice and sharp at all volume levels. I never moved gain controls from the half way position was shipped with, and. I have awesome sound!! Alpine always underrated!!! Yes, buy it!! Atleast when speaker are matched closely. Head unit is 47x4 watts I believe and produces great power with this amp added!!
Review: Crystal-Clear Sound and Power You Can Feel! - I couldn’t be happier with the Alpine S-A32F S-Series Amplifier. I’ve been upgrading my car audio system piece by piece, and this amp was the perfect addition. The sound is incredibly clean, powerful, and well-balanced across all channels. It brought my speakers to life in a way I honestly didn’t expect—zero distortion, even at high volumes. Installation was straightforward, and the compact design made it easy to fit in a tight space. I also love that it's a Class D amp, so it runs cooler and more efficiently than my old setup. This amp is perfect if you want serious sound quality without breaking the bank. Alpine really nailed it with this one—it delivers professional-level audio performance at a great price. Highly recommend it for anyone looking to elevate their car audio game!

## Questions & Answers

**Q: how will this amp work with 2 jbl 6.5 and 2 jbl 6x9 speakers**
A: Perfectly. 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.

### ⭐⭐⭐⭐⭐ Alpine quality for a great price.
*by T***9 on May 22, 2025*

I needed to replace an amplifier that died and I didn't want to skimp on quality; so when I saw this amplifier at a great price I didn't hesitate. First I am really happy with the build quality and aesthetics, my only disappointment is the wire terminals are just small set screws without a wire clamping system. I recommend terminating your wires with pin connectors. For the power and ground wires(8 gauge), I had to improvise pin connectors from larger gauge ring terminals. This improves and makes connections secure. I have been impressed by the sound. Punchy, deep bass, smooth mids and highs. Some of the improvement may be because the old amplifier was mounted under the rear deck on metal, which probably created a ground loop, and heat dissapation issues. I mounted this amp to the trunk liner with some plastic spacers underneath for airflow and wood backing behind the liner for reinforcement. This amp was about $90 less than the newest Alpine model, so this was an easy decision and I am cruising with great tunes again.
