## Description

Alpine Electronics S-A32F 4 Channel Amplifier : desertcart.co.uk: Electronics & Photo

Review: At 4x55W (RMS) this Amp provides just a little more umph than the very common 50W competition in this price range. Construction is solid. No distortion at a volume that is too loud for the average listener. The manual states that this Amp is rated for 80W per channel at 2 ohms (RMS). I was quite impressed that the manual included the factory technician's hand written value of the actual performance for my specific unit. (92W) Paired with my new 12" powered subwoofer I find myself looking for excuses to run a few errands. Only criticism is that it did not have any pre-outs.

## 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.

*by S***P on 12 December 2025*

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!!
