KX400.4 Amplifier

The KX 400.4 Four-Channel Amplifier is built to power all your door speakers in a small, powerful package.


Using powerful Class D technology, this amp features FIT™ (Fail-Safe Integration Technology) – giving you superior power, clarity and dependability. A powerful 24dB DSP (digital signal processor) controlled crossover and 24dB subsonic filter is included, letting you quickly tune your system to perfection. Use the full range RCA outputs to run another KX amplifier off of the same signal.


This KX amplifier delivers as much as 100 watts per channel (4 channels driven), or 200 watts into two sets of bridged channels. See below for more details.
