The KTA-30FW 4-Channel Power Pack Amplifier produces 400-watts of Alpine’s Exclusive Dynamic Peak Power for big subwoofer power in a small space. With the highest performance value on the market, this 4-channel-power amplifier provides an easy update path to add more bass to a sound system in vehicles that don't normally have the room for a traditional amplifier. Utilizing Alpine's exclusive Dynamic Peak Power (DPP) technology, the 300-watt KTA-30FW delivers bursts of power to meet the peak demands of music, effectively rising to 600-watts and then rolling back to maintain efficiency. With the compact, Power Pack design, the amplifier can fit in hidden areas, like a glove box, under a seat, or mounted behind a receiver to optimize power and space in the vehicle. The KTA-30FW is weather-resistant and rated IP66, so it’s protected from limited dust ingress and low-pressure water spray from any direction. The rugged chassis and high-quality waterproof so it can be used in installations where it will be exposed to the elements, like side-by-sides, boats, open-top vehicles, and motorcycles.
