Load Generation for Factory Audio

The AudioControl AC-LGD is a load generating device and signal stabilizer designed for car audio upgrades. It addresses issues in modern factory Class D amplifier systems that can mute, distort, or emit damaging frequencies when original speakers are removed. The device uses carefully selected resistors and a Zobel Network to generate load and stabilize the signal. It ensures the best possible audio quality for aftermarket equipment.

Stable Signal Under Continuous Operation

The LGD maintains consistent load generation and signal stabilization during sustained audio playback. Its passive resistor and Zobel Network design operates without active components that could overheat or degrade over time. The unit handles continuous factory amplifier output without muting or distortion artifacts. Performance remains steady regardless of volume level or duration of use.

Simple Integration With Pre-Wired Connectors

Each pair includes pre-wired connectors with standard wire colours for front and rear channels, allowing direct connection to AudioControl factory upgrade products. The compact dimensions of 2.3L x 1.0W x .06H without wires fit easily behind panels or in tight spaces. Installation places the LGD between factory speaker outputs and line output converters or speaker-level inputs. The lightweight 1.4oz units add minimal mass to the wiring harness.

Questions about this item

Does the AC-LGD generate heat or draw power when installed in a system running all day?

The AC-LGD uses resistors and a Zobel network to generate load and stabilize signal; it has no active circuitry, so it produces no measurable heat and draws no power of its own.

What factory wiring must already be present for the AC-LGD to function?

You need factory speaker outputs available; the LGDs connect between those outputs and your line output converter or amplifier speaker-level inputs using the pre-wired connectors included.

Will the AC-LGD work with an older amplifier that only accepts speaker-level signals?

Yes, the LGDs are installed between the factory speaker outputs and the speaker-level inputs on any amplifier or processor, making them compatible with older gear that lacks line-level inputs.
