PAC SNI-15 Speaker Level to Preamp Adapter/Output Converter

The PAC SNI-15 is a professional-grade 2-channel line output converter (LOC) designed to safely add an aftermarket amplifier or powered subwoofer to a factory radio that does not have RCA pre-outs. It converts high-level speaker wire outputs (up to 15 watts per channel) from the factory head unit or factory amplifier into clean, low-level RCA signals that your new amp can use — all while maintaining proper signal grounding and eliminating noise.
