The KS amplifiers are a totally "out of the box" rethink of what an amplifier can be. By taking a proven but underutilized Pro Audio amplifier class and bringing it up to date with modern components we can achieve uncompromising sound quality in a compact chassis that makes installation in even the most challenging cars and trucks a breeze. 
 
Switching to a higher class. Class G and Class G/H amplifiers offer the best of all possible characteristics. Power output, distortion, efficiency, heat, noise, size are all class leading specs with this design. 
 
Why does this class or amplifier perform so well? It's built for music, not test tones or noise. Class G/H works with the dynamics of music not against them. When an amplifier is playing music even at full volume, due to its dynamic nature, it is really only working above 1/2 power about 100% of the time. You only need full power during the very loud passages like the impact of a drum or the pluck of a bass string. The rest of the time your 2500 watt amp is making less than 1200 watts. That's where the KS amp's Class G/H comes in. It's like having 2 amps in one. A 400-watt amp that can be a lot smaller and makes a lot less heat that in a fraction of a second becomes an 800-watt monster. The trick of making this work is striking a balance between switching this high power section on and off. It takes the years of experience Nikola Engineering has to achieve this delicate balance.
