Alpine S2-A55V S-Series Class-D 5-Channel Amplifier, Hi-Res Certified, 40W x 4 + 200W x 1 @ 4 Ω, 60W x 4 + 300W x 1 @ 2 Ω

I did a complete stereo change in my truck. I've used Alpine amps in the past and knew I could expect a clean amplified signal.This amp did not disappoint. Paired with a new deck, speakers and an under seat box this has given the sound quality I was looking for.It is not a base pounding, annoy everyone around you, amplifier. It provides a moderate boost for those of up that want a nice clean sound that lets you hear everything.~Cheers

I installed this under the driver seat of a 2023 Tacoma. Fits perfectly. It is powering Audio Control 6x9 components and a 10” JL sub. I thought the relatively modest 40 watts per speaker wouldn’t be enough but my speakers are 3ohm and this amp is stable into 2ohms so output is more like 50 watts per speaker. My sub is 2ohms and this amp puts out 300 watts into a 2 ohm load. So everything sounds pretty big and glorious. I had planned to move up the Alpine ladder to a higher end amp but this thing sounds really good.
