Audio upgrade help please
Just "finished" an audio upgrade 2016 F150 Lariat w/Nav no sony.
I installed all new morel speakers and an alpine pdr-75 amp
i used a parrot harness and used rca converters + rca cables to send signal to the amp then ran a speed cable up front to connect to the harness then out to speakers.
I now have a buzz as soon as i press the truck start button and it continues (you can hear it with the songs too) and even after i turn the truck off and open the door. The amp stays on for about a minute then turns off. No buzz once amp finally turns off.
Does it sounds like i need to run a separate remote wire? or whats the deal?
I used the factory ground in the back of the cab cable is about 1.5 ft

I believe the output signal even from non-Sony systems is "High Level" outputs. That's why you'd be getting the buzz/humming through the speakers since you used an RCA converter. FORSCAN has the ability to convert them to low level outputs, doing that should fix it all. Also, if you've got the 3.5 or 2.7 you can use that to turn off the fake engine noise that goes through the speakers.

Try the Forscan inputs. From reading this thread it seems like it would help. https://www.f150forum.com/f30/anyone...373202/index5/
