Use cases: - Upgrade a factory head unit without RCA outputs by adding an external amplifier for improved front-stage performance. - Integrate a standard stereo with an external amp in a custom installation requiring RCA inputs. - Quick, reliable turn-on signal to synchronize an amplifier in a multi-amp setup using the amp’s power supply.
