Product Description

Features & Specifications



Alpine KTA-30FW Tough Power Pack Compact 4-Channel Amplifier

Alpine KTA-30FW Tough Power Pack Compact 4-Channel Amplifier is a super-compact, weather-resistant power pack to give you higher power output and better dynamic range for open-air vehicles, such as ATVs, side-by-sides, motorcycles, and boats. This Class D amplifier can be used with factory head units or aftermarket sound systems. The KTA-30FW comes with a single harness with all of the power, input, and output connections, terminated with a water-resistant 26-pin connector.

A Sound System Boost Without the Big Space Commitment

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’s exclusive Dynamic Peak Power (DPP) technology which uses a new 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, rated at IP66 for protection against 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 side-by sides, boats, open-top vehicles and motorcycles.

Half the Size of Our Smallest Traditional Amplifiers

The KTA-30FW measures just 9 3/16″ (W) x 1 5/8″ (H) x 3 3/4″ (D), so its small footprint lets it fit where most amplifiers won’t. The KTA-30FW can be tucked away under the dash or in the glove compartment, installed under the dash of a side-by-side, placed in the saddlebag of a motorcycle, or used in other places where space is an issue

Single brick size, hits you like a ton

Need more power for your speakers but don’t have space for a big amp? Alpine’s KTA-30FW Tough Power Pack amplifier can put out 75 watts RMS to each of your vehicle’s four speakers. The amp’s compact, weather-resistant chassis and waterproof connector make it a great solution when you need 4-channel amplification in your side-by-side, UTV, boat, motorcycle, Jeep, or convertible where contact with water and dirt become issues. And I’m not kidding when I say this amp is small — with about a 9″x4″ footprint, it’ll fit just about anywhere.

Special sauce

The KTA-30FW uses Alpine’s Dynamic Peak Power (DPP) technology to deliver a quick energy boost when needed, virtually doubling the amplifier’s output power on musical peaks. The gain and crossover controls sit protected behind a water-tight panel, so even a sudden downpour won’t spoil the fun.
