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.
