Mono Power Pack Amplifier with PowerStack Capability - Dynamic Peak Power Ratings 1 x 400W @ 4 Ohms


The KTA-200M is a very compact mono amplifier, that is mainly designed to be power-stacked with the iLX-W650BT, but can also be used stand-alone in any universal configuration.

Featuring Alpine’s Dynamic Peak Power (DPP) technology, the KTA-200M can produce 400 Watts of Alpine’s Exclusive Dynamic Peak Power for big subwoofer power in a small space.

Product information

PowerStack Capable

The KTA-200M utilizes Alpine’s compact Power Pack design to fit in hidden areas like a glove box or behind a radio to optimize power and space in your vehicle. Mounted behind the iLX-W650BT 7-inch Digital Media Receiver, the KTA-200M becomes (next to the KTA-450 4-channel amp) the newest PowerStack product, for an easy, hideaway bass solution that adds more power to the sound system while occupying the same depth as a traditional 2DIN radio.
