System Integration Examples

System Example 1 (Toyota Tacoma)

This example illustrates the integration for a 2005-2019 Toyota Tacoma with a non-amplified stock system featuring 6 speakers and no subwoofer. It shows a PAC T-harness (LPHTY01) connecting to the factory radio. An AudioControl amplifier (e.g., ACM-4.300) is depicted receiving signal from the harness and powering the speakers. Two green AudioControl AC-LGD modules are shown, facilitating the connection between the harness and the amplifier, ensuring proper signal integrity.

[Diagram Description: A simplified diagram showing a Toyota Tacoma vehicle. Arrows indicate signal flow from the factory radio, through a PAC T-harness (LPHTY01), to two AC-LGD modules, then to an AudioControl amplifier (ACM-4.300), and finally to the vehicle's speakers.]

System Example 2 (OEM Amplified System)

This example demonstrates integration for a 2005-2019 OEM amplified system. It features a PAC T-harness (APH-TY02) connecting to the factory radio and amplifier. An AudioControl amplifier (e.g., ACM-4.1200) is shown receiving signal from the harness and powering the speakers. Four green AudioControl AC-LGD modules are depicted, connecting the factory system, the harness, and the amplifier to manage signal load and prevent distortion.

[Diagram Description: A simplified diagram showing a vehicle with an OEM amplified system. Arrows indicate signal flow from the factory radio and amplifier, through a PAC T-harness (APH-TY02), to four AC-LGD modules, then to an AudioControl amplifier (ACM-4.1200), and finally to the vehicle's speakers.]

AudioControl LGD Modules: Essential for OE Integration

AudioControl LGD (Load Generating Device) modules are crucial components that install between the factory signal source and aftermarket equipment inputs. They simplify installation and provide an inexpensive way to ensure your OE integration performs optimally.

How LGDs work: Today's factory sound systems often utilize Class D amplifier technology. This technology can sometimes mute, distort, or emit damaging frequencies to new aftermarket audio equipment when the factory system no longer senses an impedance load on its outputs. The AC-LGD series, using carefully selected resistors and a Zobel Network, generates a proper load and stabilizes the signal from the factory system, ensuring the best possible audio output.

LGD Module Types:

• AC-LGD60: For 2018+ vehicles with amplified OEM systems.
• AC-LGD: For 2005-2015 vehicles (All Makes/Models).
• AC-LGD20: For 2018+ vehicles w/o amplified OEM systems.

Common Vehicles Benefiting from LGDs:

• Toyota
• Chrysler
• Dodge/Ram
• Alfa Romeo
• Jeep
• Subaru with STARLINK
• Honda
• Fiat
• GM
• Ford
• Harley-Davidson
• Maserati
