Krypt Class G/H Mini KMA 125.4 is the most powerful amplifier of its size, and is feature rich to satisfy all audiophiles. The class G/H topography is much more efficient and produces less distortion than Class D amplifiers. We also marine graded the internal electronics by adding a conformal coating to protect your investment against water and corrosion. This amp is designed in a miniature form to reduce the overall footprint for installation in tight areas.

Simply put this amplifier packs a huge punch in a small package. The advantage of a Class G/H amplifier is significant over a traditional Class A/B or D amplifier: the most important being power efficiency. The difference between classes is the more efficient power supply: the higher the class; the more efficient the power supply typically is (Class A/B is the least efficient). Class G/H amplifiers are 30% - 50% more efficient than standard Class D amplifiers. What this means to you as a boat owner is 30% - 50% more battery time when your boat engine is off; which in return makes it less likely to add a costly 2nd battery, and more importantly gives you peace of mind that your boat will start after playing your stereo for long periods with the engine off. Because of this high efficiency design you get one more added benefit: Most amplifiers are installed in a location that gets very little air flow, and amplifiers need air to cool down or else they will go into an overheat protection mode which shuts down the amp until it is cool enough to play again. Class A/B and typical D amplifiers installed in a boat and operating at 75% or above can normally only play up to 45 minutes without overheating during summer time temperatures; Class G/H amplifiers in the same environment will not overheat.

This is the perfect amp to push Krypt HLCD Speakers, or internal boat speakers
