Tweeter not working correctly

[CarstenG]

I installed an amp and tweeters in my bronco and everything was working totally fine but now all of a sudden the tweeters on my driver side aren’t playing any sound. If I unplug and re-plug the speaker wires and RCA cables back into the amp it all of a sudden works with no issues but only until I turn the car off. Once I leave the car off for 15 or so minutes when I refire it on they don’t work again.

Any ideas what this might be and how to fix it?

You have access to a scan tool or Forscan??

I wonder if the ACM is cutting off power to your aftermarket amp for some reason.

I do have access to it but not much experience. What should I do to check that?

Check the DTC codes (Diagnostic Trouble Codes) and see if the ACM is reporting anything. If you are using Forscan there is a yellow triangle "DTC" button on the left hand side of the UI specifically made to check them.

I can say my ACM throws “missing speaker” DTCs for my speaker level inputs but continues to play.

There may be a “short circuit speaker” code that does cut them out though, but I don’t know that for certain.

how do you correct DTC codes that say open circuit for speakers #1-4 after kicker amp/speaker install?

A few days of rest and care will work wonders:

What amp?

What amp?

kicker key and 500 for sub. maybe faulty harness?

Either that or the Kicker Keys don't generate the load the ACM is expecting, and you'll need to add either a load generator or a line-output converter.

Is music actually playing or no?

yes

 

[RagnarKon]

yes

Ah okay. If music is playing, then it's not the harness. You just need to add a load generator.

AudioControl AC-LGD 20 would be my choice.

Or obviously you can just ignore the DTCs.

you’re the man thank you now if you could just write a “for dummies book” about Bronco audio!

Would I also need these load generators?
Had the speaker delete on my Bronco. We installed a Fusion amp and Skar sub. Also, replaced front and pod speakers with Skar Audio (upgraded rear to 6.5"). Since then I have been experiencing intermittent issues with front and pods speakers not working. Sometimes when I start up vehicle there is no sound from any of the speakers. (rear sub works all the time). They will continue to not work for the duration of that drive. I can sometimes shut off vehicle and restart to get them working. Sometimes it works sometimes it doesn't. I just learned of the Power and arrow button to reboot. Tried that with no luck.
Also, on some other thread someone mentioned an electronic whirring/clicking that sounds through the speakers when they open doors to get in. I also hear this occasionally. I believe that i can hear it when the speakers are going to work and DO NOT hear it when the speakers are not going to work.
