Premium Audio Custom Installation

Depending on the configuration of your AU Falcons current audio system, certain different parts may be required. As a result, a section has been made for a couple of common configurations:

No listed configuration allows for the use of the Premium Audio headunit or the premium audio body loom, due to a lack of resources and the unlikely scenario where a premium headunit was fitted to factory without the wiring provisioned to install an amplifier and subwoofer “plug-and-play”.

In addition, all configurations listed here are at least partially made from factory parts. There is sufficient information in this page to create a complete custom solution, but this was deemed out of scope.

Note on Diagrams

All diagrams in this page are indicative only, as they are not “true” electrical diagrams. Every effort has been made to make the diagrams comprehensible through the use of approximate imagery and colours, however nothing on the diagrams are to scale, only “to shape”, and only to a degree

Configuration 1 - “AU Purity”

This configuration contains all factory AU Falcon parts wherever viable and possible.

Factory amplifier boot loom not used as one connector is unidentified

Audio level of rear driver speaker may be diminished due to splitting the output to a Crossover. This may be partially fixed using Fade & Balance combinations but must be considered if this method is used

Common step - Connecting the Sumitomo Terminal to the Cabin Fuse Panel

All of the preceding configurations require that you remove the cabin fuse panel and install a Sumitomo terminal into the factory location for the amplifier circuit. Follow the instructions below to perform this step:

1. DISCONNECT THE BATTERY
2. Remove the 2 phillips head screws holding the panel into place, and gently pull the panel from the dash

3. Locate and disconnect the 2 position brown connector from the rear of the panel.

   This connector should only have one terminal pin populated. If this is not the case, your vehicle likely has the premium audio wiring loom, rendering this page useless to your specific vehicle.

   

   Picture of the front and rear of the connector to be unplugged from the fuse panel

4. push your terminated wire into the empty position in the plug housing, and reinstall into the cabin fuse panel

   Due to age, there may be dirt or other build-up in the plastic housing. For best results, clean this cavity before performing this step

5. Reinstall the cabin fuse panel into the vehicle, ensuring both screws are tight.

6. (Optional, if fuse previously removed) Install a 20A fuse into the AMP fuse location on the cabin fuse panel.

7. Reconnect the battery and test that the circuit receives power using a multimeter.
