RF-HLC4

The RF-HLC4 is a 4-channel high-level to low-level signal converter designed for factory or aftermarket radios that do not have dedicated low-level RCA outputs.  The adapter converts high-level signal from the radio's speaker line and transforms it into a safer low-level audio signal.  This allows you to add a 4-channel amplifier to your system for higher power output and better sound quality.
