Alpine_R-A90S
Compact Power and Maximum Impact

The KTA-30MW Weather-Resistant Tough Power Pack delivers big amp performance in a small, rugged package. Featuring Alpine’s exclusive Dynamic Peak Power (D.P.P.) technology, it pumps up to 600 watts of punchy bass for subwoofers in open-cab vehicles and powers your system effortlessly with either aftermarket or factory head units. Built to brave the elements, this weather-resistant amp thrives in side-by-sides, boats, open-top vehicles, and motorcycle saddlebags.

Dynamic Peak Power for Explosive Sound

Exclusive Dynamic Peak Power (D.P.P.) technology intelligently adapts to your music, delivering up to twice the power during rhythmic peaks like snare drums, trumpets, or high-hat cymbals. D.P.P. prevents clipping by instantly supplying bursts of power when needed and quickly rolling back to maintain efficiency—ensuring your music stays punchy, precise, and distortion-free.

  • Love how Alpine was able to craft an amp this size and still be able to deliver a good amount of power for a sub amplifier. Its said to be all weather, so I think it can be used not just for cars, but I don’t have a boat or an ATV so I’m gonna use this amp for my vehicle hopefully for many years.

  • Small and compact, yet packs plenty of power for my Alpine sub. Excellent quality all around.

  • I have some issues with its on light since it doesnt have one. It's hard to know if it's on or not and is draining my battery as I don't have any thing to look at whether it's working or not. Nice that it's sealed and feels like a durable amp. Good power output for my Kicker sub to bring out some more volume from it.
