Alpine S-A55V, S Series Class D 5 Channel Amplifier

Works perfect and sounds great. Easy install and adjustment.

Very impressed with this amp. I’m powering 4 type-s 6 1/4” door speakers and one dual voice coil type-S 12” subwoofer and it is so loud and clear. Recommend to anyone.

Just what you would expect from a brand like Alpine. This beautiful little but powerful amp gave life to my car audio system. Matched with some JBLs GTOs component speakers, u can't go wrong with this amp, installation is pretty straight forward, just connect all cables required and you're done. let the music blast!

Recently was looking around for a good mid-range 5 channel amplifier to put in a 2017 TOYOTA Corolla and found this APLINE S-A55V, once all the wires were ran and paired with only a subwoofer and stock speakers. THIS AMP PULLED THROUGH. The amp upgrade alone made the sound quality in the car feel premium. The adjustments are easy to tweak, no hissing, whirling or buzzing of any kind. As well as having a small foot print. Highly encourage and recommend to anyone looking to upgrade from stock audio.

I wish I would have hooked this thing up sooner, because my return date expired. I hooked everything up. Found out channel 1 and 2 turn the amp off, if it's up too loud. No clipping signal or anything just straight shuts off. very disappointed in Alpine. Left it hooked up cause I can't return it. But the other channels seem fine. Idk if there's any warranty, but I don't think I'll be buying any Alpine brands off Amazon anymore! Real let down! I bought this for a small easy and clean system. But now probably just gonna run a two amp setup. One 4 channel one mono, instead of the 5 channel

The sound quality is great, especially given the relatively small overall size of the amplifier. Paired with an Alpine iLX-W650 head unit in my Yukon, this amplifier powers two 6.5" speakers in the front doors, two more 6.5" speakers in the rear doors, and an 8" sub-woofer in the rear cargo area. The amplifier is mounted beneath the center console, just in front of the cup holders. Removing the cup holders (with just a tug, no tools required) provides access to the adjustments on the amplifier.

Installed on a boat 22 ft open bow jet boat, pushing 4, 6 1/2 pioneers and one 10-in Alpine type-S in a custom fiberglass vented box. Can't say enough good things. The pioneers really came to life, and the sub pulls harder on the lower... Pretty sure I haven't broken it in yet. 20 hours of runtime so far, no problems no heat!

Amazing product
