Bypass your factory radio's shut down circuit Some factory radios and amplifiers will not work without sensing that speakers (low-impedance loads) are connected to their outputs, so successfully installing an aftermarket sound processor or amplifier becomes a challenge. AudioControl's AC-LGD Load Generating Devices solve this issue by generating an acceptable impedance load and stabilizing the signal for the factory system to handle. The AC-LGDs plug directly into any AudioControl line output converter (LOC), signal processor, or amplifier with speaker-level inputs. You can also use AC-LGDs with almost any non-AudioControl device by replacing the connectors.
