Alpine - 300W Class D Multichannel Amplifier - Black

The “Tough Power Pack†series includes two new amps with small foot prints and an IP66 rating against water and dust. Both the 4-channel KTA-30FW and the mono KTA-30MW use a “high-quality†waterproof connector †making them ideal for use in exposed areas such as side-by-sides boats open-top vehicles and motorcycles †said Alpine. They use Alpine’s proprietary Dynamic Pulse Power (DPP) technology which “delivers bursts of power during rigorous musical passages. When the amplifier senses that more power is required the power supply quickly increases the internal gain level effectively doubling the power for a significant increase in music volume †Alpine said.

Key Features and Benefits: A sound system boost The KTA-F30W is perfect for when you want to boost your sound system but don't have the space for a large amplifier. It is compatible with an aftermarket or factory head unit and adds up to 4 times the power over the head unit's original built-in power. Dynamic peak power The KTA-30FW features Alpine exclusive technology which uses a dynamic power supply design that delivers bursts of power during rigorous musical passages. When the amplifier senses that more power is required, the power supply quickly increases the internal gain level, effectively doubling the power for a significant increase in dynamic range at high music volumes. Weather-resistant format The KTA-30FW is ready for your adventures. It is weather resistant for protection again dust ingress and high-pressure water spray. The KTA-30FW features a rugged chassis and high-quality waterproof connector so it can be used in installations where it will be exposed to the elements, like boats, open-top vehicles, and motorcycles.
