- Maximum Watts x Channel @ Ohms: 150 x 4 x 2; 150 x 4 x 4 (This is the maximum load the speaker, subwoofer or amp can drive.)
- Amplifier Class: D (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
- Number Of Channels: 4

- Audio
- Number Of Channels: 4
- Minimum Frequency Response: 15 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Maximum Frequency Response: 36 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)

Bring your music outdoors with this Alpine four-channel amplifier. With a weather-resistant power pack and waterproof connectors, it's ideal for use in open vehicles, and its compact size makes it easy to store in motorcycle saddlebags. This Alpine four-channel amplifier senses when it needs to increase the internal gain level for louder volume.
- 300W total power: Features RMS rating of 75W x 4 at 4 ohms/2 ohms, and is four channels driven for robust audio.
- High- and low-pass crossovers: Ensure flexible operation.
- 4-ohm impedance: Conducts power evenly to keep the speaker at an appropriate level.
- Dynamic Peak Power (DPP) technology: Delivers bursts of power during rigorous musical passages.
- Class-D circuitry: Ensures reliable power handling.
- Weather-resistant design: Rated at IP66 for protection against dust ingress and high-pressure water spray. Good choice for use in exposed installations, such as side-by-sides, boats, open-top vehicles, and motorcycles saddlebags.

Hear the Difference with this Simple Power Upgrade!Add higher output and a more dynamic response with this easy-to-install Alpine head unit Power Pack upgrade. The KTP-445A Power Pack amplifies power output on select 2005 and newer Alpine head units, resulting in up to a 150 percent power increase over the original power from the head unit's built-in amplifier.Overview45 Watts x 4 @ 4Ω/2ΩFor select 2005 and newer Alpine head unitsCompact sizeEasy Installation and FlexibilityCompactCompact size lets the KTP-445A fit where most amplifiers won’t. The KTP-445A comes equipped with direct plug-in connectors for select 2005 and newer Alpine head units and it fits behind the dash of most vehicles. It's small and compact at only 7-7/16” x 1-1/2” x 2-1/2”. Its size and flexible wires make the Power Pack an easy choice to save space.Best Signal-to-Noise Contender In Its ClassIn order to ensure that Alpine sound quality is heard, we’ve created a platform that offers an unbelievably low noise floor, taking extra care to ensure a clean signal path, with no extraneous interference. The end result: The Power Pack boasts 1 Watt Signal-to-Noise Ratio of 82dB or better.Total Harmonic Distortion (THD+N) vs. FrequencyUniquely, the Power Pack distortion actually decreases at higher frequencies, resulting in a clean and clear signal where your ear is most sensitive to distortion. - <0.03% THD+N @ 1W, 1% THD+N @ rated power.
Listen to your favorite Hi-Res music and podcasts with this Alpine four-channel amplifier. The Next-Generation R-Series Amplifiers are Hi-Res Audio Certified and able to reproduce up to 45kHz frequency response. This ultra-wide bandwidth brings music even closer to the original source while the classic R-Series design maintains the “loud and fun” performance quality that long-time fans have come to enjoy. The R2-A60F features a reduced footprint that’s 15% smaller than the previous model (R-A60F), making it easier than ever to install in most vehicle applications while still getting the same powerhouse performance.
