Sorry to cross post, but I'm trying to find other 2010 owners to test out an audio problem some of us have noticed.

There seems to be an issue with the non-Navigation Shaker 500 system in our 2010 Mustangs. The problem is that there's a hiss or drone at low volumes (0-2 bars) coming from the door subwoofers. It's easiest to hear the noise when the engine is off with the key in ACC mode. Simply turn your volume down to 0 bars and see if you can hear this mysterious noise coming from the subs. We currently have an active thread on this subject but I'm hoping some additional owners can quickly read through the posts and then add their findings. The more people we can get to verify this issue, the quicker Ford will release a TSB.

Please click here and post your results.

This seems to only be affecting Shaker 500 non-Navigation Mustangs. It may also be present in the Shaker 1000 systems but we haven't had any owners with this option chime in yet.

 

Those with this issue, please see the post here: https://mustangforums.com/forum/6370199-post18.html

 

I'll let you know as soon as mine comes in...ordered since April 26. I'm not sure if I'm Job 1 or Job 2 though.
