I tried searching about the issue but didn’t find anything.

For some reason, when I power on the radio the acoustic system in the back starts to make a loud sound which sounds like the speakers are reverberating but no actual sounds is coming out from the back speakers. When the radio is powered off, the sound stops.

Any thoughts or help? Thanks.

Here is a video of the noise:

That is very interesting, and I have never heard that. Because of the age of the system, I mean it could be anything. When you look at the wiring diagram, you will notice the Wave gets input directly from the head unit. I would start with the simplest thing like making sure all connector are clean. Spray a little electrical contact cleaner in every connector. If still nothing, then you may have to start testing at the outputs of the head unit, the Bose snake amp, and the drivers themselves.

How many miles does your FD have? I'm impressed you still have the stock headunits and stock shifter. Even your center console looks extremely clean.

Awesome! I will get that a shot. Any advice on how I would go about testing the outputs?

The FD has 28k on it so everything is stock inside.

Thank you.
