Installed new door speakers and 4ch amp now no line in or bluetooth audio!!!
 

well let me start by saying this was harded than i rember it being. well stsrted at 8am and just got finished at 8pm minus a lil screw off time. Any way i installed 4 polk db571's in doors, an old alpine 4ch amp in back with the pac-AOEM_FRD24, and stock head unit in my 2011 f150 screw. speakers work and i can use the phone but when i tell it blue tooth audio, usb, or line in the sync women repeats me the radio flashes but it goes back to f.m. radio or whatever it was on.do i need a different adapter? do i need a second adapter? please help cause this sucks!:help:

I just received a call from my installer that this would be an issue. Maybe I don't fully understand SYNC either.

Well update, got in truck this morning and everything worked fine. Go figure.

Very strange indeed. My installer told me that he called PAC morning and they said it wouldn't retain SYNC because I have a late build '11 with a '12 stereo. I was like, "Huh?"

Maybe I need to dig a little deeper and find out why PAC would tell him that. I'm happy you got yours going...gives me hope at least.

I installed the PAC unit and have no issues at all. No issues with Sync.

well, minus all the SYNC issues, how does she sound with the new door speakers? Looking to upgrade mine at some point cause I have the cheap stock system with no sub.

sounds awsome, way better than the stock speakers. but i am also powering them with an amp not the stock headunit.as soon as fox sends me my box i will be putting 2 10's under the seat in a ported box.
