## Description

Get a huge increase in sound performance over your factory system. With Alpine’s exclusive technology, Dynamic Peak Power (D.P.P.), the KTA-30FW Weather Resistant Tough Power Pack is sure to add higher output and increased dynamic range for those open cab vehicles and toys. Specifications: Alpine's Class D amplifier circuit with Dynamic Peak Power (D.P.P.) Weather resistant (IP66 rating) 150W x 4 D.P.P. (2Ω/4Ω, 14.4V, ≤ 1% THD+N) CTA-2006-B Specifications: 75W RMS x 4 (2Ω/4Ω, 14.4V, ≤ 1% THD+N) 82dB S/N (ref. 1W into 4Ω) >0.05% THD OEM-grade Tyco 26-pin connector with pigtail wire harness Speaker/RCA inputs (Selectable, High range=0.5-10V, Low range=0.2-4V) Sound control: Crossovers: Off/HP/LP, Fc=50-400Hz @ -12dB/Oct. (variable) Input gain settings (variable) 2ch/4ch input (selectable) 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.

Review: For 3 years I’ve ran the Alpine KTP-445A which is an outstanding amp but I was looking for a little more power to keep up with my subs. This one is a little bigger but it still fit behind the Alpine iLX-w650 in my 2005 Silverado. Clean and crispy with great punch with the added 25 watts per channel. Really made a big difference.
Review: I bought this amp to replace a larger Kicker amp of the same power. While this amp does a great job with a small package, it picks up ignition noise in a big way. I was able to get rid of nearly all of it by installing a noise filter in the system, but I shouldn’t have to do that. I had zero noise on the previous amp and am using the exact same connections. Power and ground are straight from the battery and record no resistance when checked. It does sound good, but I expected better from Alpine.

## Features

- 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.
- Weather resistant: IP66 Rated Amplifier

Alpine amp brought my speakers alive. Easy to install, just takes some time and a lot of splicing. Use RCA cables in between your head unit and amp. Need an amp wiring kit. Creative Audio Seller has amazing customer support and is the go to seller. Going to buy all my audio equipment from them.
