Alpine S2-A36F S-Series Class-D 4-Channel Amplifier, Hi-Res Certified, 60W x 4 @ 4 Ω, 90W x 4 @ 2 Ω

This Alpin powers 2 (soon to be 4), 30+ year old realistic (Radio shack) minimus 7s midway back in my old T1N Sprinter based camper van. The head unit is a big 10 inch display cheap ($300) BOSS Audio Systems BCPA10RC that has a lot of feature sounds OK powers a couple of kenwood 3/12 two way in the front dash and preamps out to the Alpine and a Kenwood KSC-SW11 Compact Powered Enclosed Subwoofer. So basically a mid grade 4.1 speaker car stereo system for about a grand. I did my first shakedown trip from NY to Florida and I primarily used Pandora thru Apple Car Play and it sounds great... and I have a 15k home theater system... . Overall, the Alpine Poweramp has great stereo seperation and the clarity and power were very good and I was basically only using half of it.

I think the sound quality is excellent for the money that I spent. It’s always fun to find something that’s reasonably priced that gives great value.

Solid Amp, in the short time I've had it never had an issue. The soundstage is fantastic for the price point.

I built a system for my 2021 Ram and started with this amp, paired it with dash, front doors, rear doors speakers. Integrated it with the factory touch screen and this amp is loud! It pushes the infinity reference speakers to almost perfect performance, I have a 18 speaker set up including two 10” subs on a 2000 watt amp and had to turn the Alpine amp gain down to half way to balance the subs and surrounds! The truck rocks 1000 times more than with the factory setup now!

Sonido excelente pero se protege con mucha facilidad , no estoy muy conforme , desmonté una Soundstream Picasso que la superaba en potencia y estabilidad aunque no con el sonido de Alpine , muy decepcionado
