The Rugged Radios 3.5mm mono Y-splitter is a compact cable accessory that splits a single 3.5mm mono external speaker output so two devices can be fed from one jack. It provides a simple, plug-and-play way to duplicate a mono audio line for intercom or speaker setups, enabling neat routing in helmets or dash mounts without changing your radio or speaker wiring.
