D Series Amplifiers provide a powerful solution in a compact design, ideal for upgrading your car audio system.

Expanded Frequency Response

Supporting Hi-Res Audio, KAC-D3104 is ideal for high resolution audio playback as it features a frequency response that extends to 50kHz.

Dual Sigma Drive

This advanced negative feedback circuit improves damping factor and increases accuracy and sound quality. When a signal is passed to a subwoofer, like a 50Hz note, the speaker will move and create the note. However, because the speaker has mass and a suspension, it won't stop moving once it's in motion. This extra movement (sound) creates a type of distortion that's not part of the original signal. The negative feedback circuit senses this unwanted movement and sends out an opposite pulse to stop the speaker like an electronic brake.

Small Size Big Power

The KAC-D3104 is small in size but with its tremendous sound output, it is extremely versatile. It can be installed in vehicles where space is limited and is perfect for vehicle owners who don't want to sacrifice cargo room or who prefer hidden installations.
