Technology

Every channel pair can be bridged. Bridging amplifier channels to more than double the power.

EPS technology which prevents when connected to an OEM factory radio that no functions are impaired or error messages are written into the vehicle memory.

The amplifier can handle frequent power cycling from vehicles’ automatic start-stop systems, ensuring consistent sound quality even when the engine turns on and off repeatedly.

This feature eliminates the need for a separate remote turn-on wire, simplifying the installation process. It ensures that the amplifier is ready to operate whenever the audio system is in use.
