AudioControl AC-LGD
Today's factory systems use more Class D amplifier technology, which can mute, distort or send damaging frequencies to aftermarket equipment when the factory speakers are removed. Using carefully selected resistors and a Zobel network, the AC-LGD generates load and stabilises the signal from the factory system to ensure the best possible audio quality.
The AC-LGD is designed to work alongside AudioControl factory system upgrade products such as the AudioControl LC2i 2 Channel Line Out Converter or the AudioControl LC6i 6 Channel Line Out Converter.
Installation
The LGDs install between the factory speaker outputs and your line output converter or speaker-level inputs on your amp or processor. Pre-wired connectors with standard wire colours for front and rear make connection straightforward. Supplied as a pair.

About the AudioControl AC-LGD
From our tech experts at CEN
A dummy load and signal generating device, presenting the factory amplifier with the load it expects so it does not fault when the original speakers come out.
Who it suits
Anyone replacing a factory amplified system where removing the original speakers would otherwise throw an error and stop the install dead.
Our tech experts advise
Whether you need one depends on the vehicle and its factory audio specification, which we check before the job rather than on the day. get in touch. See car audio installation.

Frequently Asked Questions
Q: When do I need the AudioControl AC-LGD?
A: When you remove factory speakers and take the signal from a factory amplifier, many modern Class D factory amps can mute, distort or send damaging frequencies without a speaker load. The AC-LGD provides that load so the factory system keeps working cleanly.
Q: Is the AC-LGD sold as a pair?
A: Yes. One pair of load generating devices is supplied, with standard wire colours for front and rear connections.
Q: Where does the AC-LGD fit in the system?
A: It is installed between the factory speaker outputs and your line output converter, or the speaker-level inputs on your amplifier or processor, using the pre-wired connectors.
