PC9-440 interface is design for systems that have an OEM amplifier fitted with an ISO connection. Some amplifiers require a data-signal to switch the amplifier on.

This interface converts a standard 12v ignition feed to a data signal to remotely activate the OEM amplifier. You will need to find out if your vehicle requires this from your vehicle manufacturer.

We try to provide upto date information. If you are unsure about the model number please feel free to contact our customer service
