Alpine S-A32F S-Series Class D 4-Channel Amplifier

I needed to replace an old amp that developed a crackle to run Polk 6.5/tweeter separates and single 10 4ohm sub. This isn't as loud as my old amp but it sounds clean and the price was right. I'd buy it again.

Compact, runs cool, very clean output. Can't say there was any noticeable sound quality differences from the Kenwood Class D I replaced, but this amp runs much much cooler, which was my main reason for replacement, my old amp would run dangerously hot for the carpeted space that I had it installed.. HPF works great, easy setup, terminals and controls clearly marked.

This amplifier is small, but powerful love it would buy again

Installed in a ‘06 Toyota Corolla. Look no further if you enjoy quality, crisp sound. No shaky rattling bass. Paired this amp with 6 speakers from Infinity. 1 set of 3-way 6x9 Infinity Primus and 1 set of 6.5 Infinity components. 6 speakers total and it’s all the power I was looking for. The amp output tested a little higher than what was advertised. Exactly what you want. Can always dial the gain back a little if you have any clipping or distortion. This was my first amp install and paired it with the NVX 8gauge amp kit.

I’ve had kicker and Rockford fosgate but this little amp makes my car speakers scream . I think I better quality than the other brands that I had. For the size that it is it’s very powerful. Value for the money is perfect.

Honestly, it has more power than I expected. Great amp for the price. My ‘71 VW Bus rocks once again!

Great sounding amp. Highly recommend for this price point.

I ran this amp with some alpine dual coil door speakers(6x8s front,5x7s rear) in my 2003 f250 crew cab. Along with an alpine type s 10” woofer paired with a 200 watt arc audio amp. It might not sound like much but it slaps!! Volume all the way up with the amps tuned and equalizer tuned correctly there’s zero distortion, loud clean crisp sound and thundering bass. I’m very happy I decided to buy the better equipment.
