KENWOOD Kenwood X502-1 500W X-Series Class-D Mono-Channel Power Amplifier, 4Ω Stable

X Series Amplifiers provide a powerful solution in a compact design ideal for upgrading your car audio system. The reliability of the thermal management system instantaneously controls amplitude and ensures uninterrupted sound reproduction when high output drives up temperatures. Experience the luxury of choice afforded by Kenwood's compact engineering.This advanced negative feed back 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.The X302-4 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.
