Alpine KTA-30FW: 4-Channel Weather-Resistant Tough Power Pack Amplifier

The KTA-30FW 4-Channel Power Pack Amplifier produces 400 W of Alpine's exclusive dynamic peak Power for big subwoofer Power in a small space.

Through 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 W KTA-30FW delivers bursts of Power to meet the peak demands of music, effectively rising to 600 W and then rolling back to maintain efficiency.

Through 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.
