PAC SNI-15 Line Output Converter

The PAC SNI-15 Line Output Converter is a professional-grade, 2-channel device designed to seamlessly integrate an aftermarket amplifier or powered subwoofer with a factory car stereo system that lacks dedicated RCA preamp outputs. It converts high-level speaker signals from your factory radio into clean, low-level RCA signals, making it suitable for external amplifiers, processors, or DSP systems.

This passive line output converter handles up to 45 watts maximum input per channel, ensuring compatibility with most factory-installed radios. It features transformer isolation between inputs and outputs to maintain correct signal phasing and prevent ground loop noise, delivering optimal sound and performance. Additionally, a built-in subsonic filter helps eliminate speaker-damaging frequencies below 20 Hz.

The SNI-15 provides a linear frequency response from 20 to 20,000 Hz, ensuring accurate audio reproduction. It's an ideal solution for upgrading your car's audio system by adding an amplifier when only speaker-level audio outputs are available from the factory head unit.
