5.0K-A3 5000W Competition Series Class D Monoblock Amplifier

Product Description

The 5.0K-A3 Competition Series Class D Monoblock Amplifier delivers extreme power for serious audio enthusiasts. Built to handle high-output systems, this amplifier is 1-ohm stable per channel and can be bridged to 2 ohms for even greater performance. It features a variable low-pass filter, subsonic filter, and adjustable boost for precise tuning, along with a wired remote knob and clip indicator for easy monitoring and control.

This amplifier accepts dual 0 AWG power and ground inputs, providing the necessary current for high-power setups. Its linkable design allows you to expand your system with multiple amps for large-scale competition or custom audio builds. Designed for flexibility, the 5.0K-A3 can run efficiently at voltages from 14.4V up to 18V, producing massive power output across different impedance configurations.
