"Audio off" after installing aftermarket amplifiers

[l3assl3oy]

Hi everyone! I have been following this page for awhile and I have learned a lot from you guys. I am in the process of installing aftermarket amplifiers and speakers in a 2024 F150 XLT non b&o using a Y harness from provo beast. I haven't put it all back together yet because I like to test my equipment before I bolt it all up. However, I am now getting no sound at all and I cannot change sources. I unplugged the Y harness and plugged the factory harness directly into the stereo module and still have the "no audio" message and lack of source controls. What am I missing? Did I fry something? Is the stereo control module grounded to chassis with the bolts and need to be bolted down in order for me to test it? Any guidance from yall would be very much appreciated.

Equipment I'm installing:
Provo beast y harness
Audiocontrol LC5 pro
Alpine R-A150m
Alpine R-A60f
Morel components front and rear

Did you run the amp wire through the firewall grommet above the wire harness? Seems the wire like to rip apart if placement isn't perfect. Also never hook up power without knowing everything is grounded. Constant power feeding the equipment with no ground hooked up could fry something.

That's exactly where I ran the amp wire. I used a snake camera to look up in there, but i dont see any broken wires. Doesnt mean that there aren't any, but I definitely don't see any.

Everything was grounded before I hooked the battery back up. I was asking if the silver stereo control box is grounded using the bolts. I dont think it is, but I was just brainstorming. Im thinking I must have ripped a wire runming the power cable. I need to figure out how to get in there without removing the whole dash.

Ok, I have taken most of the dash apart and there are no broken wires or loose connectors. So I dont believe it is from me running power wire through the grommet behind the fuse box. I have run forscan amd gotten a a few dtcs pertaining to abs, acm, apim, tcu and bcm. Any ideas guys? Maybe a bad acm just tripping up everything else?

Where is your ground located? Is it at the battery Neg terminal or somewhere on the chassis? If not at the battery I would try to run separate ground wire to the battery and see if your system powers up. Chassis grounds are notorious on aluminum trucks for causing power issues due in part to all the bonding used on these things.
Also make sure when you were pulling power wires around that fuse box nothing got pulled and no connectors have unseated. Passenger footwell also has a secondary fuse box. Just a stab

Its possible the harness isnt built correctly. Ive had crap harnesses before. Did reset the codes?

I have bypassed the aftermarket stuff and tried getting the factory to work and that's what im having issues with. The screen says audio off and I cant select any sources. Volume also no longer displays. Im thinking I either unseated a harness where I pulled the 4 gauge through, or broke a wire. As for the aftermarket amps, they powered on fine when it was all hooked up, but I got the audio off message and to troubleshoot, I reversed it back to the stock set up. I used a snake camera to see if I can see broken wires and indidnt see any, I guess I need to start pulling the dash off to see if I unseated a harness because I cant reach up there at all.

I dont think it's the harness since I have the issue without the aftermarket stuff hooked up and the factory harness back into the stereo. I reset the codes and some did not come back, but tcu and apim not communicating came back right away.

Did you reboot them as well?

I stuck a camera in there and ripped it all apart as well the bundle of wires is very tight and the wires are fragile. I and another member broke our cruise control running through that location. Another member broke a wire that completely shut down his truck. My guess is you do have a broken wire in there you just gotta find it. Here's some pics I took from after the install and you can see theres nothing that looks broken, but my front radar harness has a short so ever since the install and I just havent gotten it apart yet to fix, theres no room to move. Do a search for broken wire during amp install and you'll see its a common problem. In that bundles there a bunch of like 30 gauge wires they rip out very easily.

The current best option ive seen is to remove the fuse box in the engine bay and pull back the rubber grommet to be able to access the full harness then just try to find whats broken. You can also try having a member run your vin and see what codes are coming back, that's how I found it was a short in the wire and not a faulty front radar. I just wish I did more research before running the wire, everything I saw online said to run it there or under the truck and I thought I was doing the right thing keeping it inside the cab. I was so very wrong.

Thank you for those links and your pictures. I'm contemplating attempting to fix it myself like in the first link since the dealership cant get me in for another 2 weeks.

Another thing you can try is the following, your head unit may just be locked up.

1. Press and hold the Seek up and the audio unit Power buttons simultaneously until the screen goes black. Wait for the system reset to complete.
2. Press the audio unit Power button to switch the system on.
