ASSEMBLED Car Interference Suppressor Module

The sound quality from even the most expensive, high-tech car sound system can be spoilt by radio frequency interference (RFI). Cars are notorious for producing high levels of RFI signals, originating from the ignition system, alternator, wipers, indicators, air conditioning, etc.

This pre-assembled RFI filter module is specifically designed to block this unwanted interference from entering your car sound system. It is very simple to install and small enough to fit almost anywhere inside the vehicle.
