Front drover door speaker quit working
Thank you for the diagrams.
Correct with no speakers connected i have a 0 ohm resistance. With the woofer and tweeter connected it has 4 ohms. I've tested pin outputs with the acm hooked back up and get 0 volts. But on the pass i get around 4.5 or so.
I was convinced that it was going into protection mode for some reason but it just seems like that channel died on the acm......

Hey guys I just wanted to say thank you for all the help. I got the Forscan tool and software. Did some reading to understand what i was looking at. Well long story short the the issue has been resolved so far by clearing all ACM DTC's.
