I have a 2013 f150 xlt with 4.3 stock head unit with sync, i just got a alpine 445u and new door speakers and was wondering what harness to use so i dont have to cut factory one to install. I talked to crutchfield the tech never heard of using the BT-5520! any help would be great i was going to let bestbuy install it and they wont to cut wires and solder P.S iam Audiotarted

 

Take a look at PAC AOEM-FRD24

I used this to wire mine up and it was simple and works great. (2010 Non Sony)
From comments (various sites) I've seen it stated that it works on 2013 (but not 2014)...

Hopefully someone here chimes up with something to back the claims. May be worth asking crutchfield bubbas if the PAC fits. They are usually pretty good at answering.

 

I did the same thing on my 2012 FX4, Alpine 445U driving POLK audio speakers in all 4 doors. I used the "OEM-FRD24" harness from PAC Audio, I was able to use the line level output for my subwoofer and I tapped into the speaker wires to feed the Alpine 445U without touching the factory wiring harness.
Hope the helps.

Hi all -

I know this thread is regarding amp replacement but I’m in a similar situation after installing a new KENWOOD receiver (replacing Sync 2) in my 2015 F150 with a factory Sony amp.

after install, all of my chimes play through the cluster and not speakers. It sounds like a Tetris gone bad game.

supposedly no codes are popping up and all speakers are fine. Amp gives sound as expected. Maestro is not being helpful to my installer.

anyone out there know a solution???
