V-Power is back and stronger than ever! V-Power amps feature speaker level inputs that connect directly to almost any factory radio, without the need for external converters, so you can keep your factory system and upgrade to Alpine sound.

With a non shut-down design, even if you pound your music for a long time, these amps won’t shut down. They use a heat thermal management processor to make sure the heat level never gets too high – which means no distortion and no interruptions.
