I've done a search and have found a few posts about this, but no answers.

I recently purchased an 07 S with the standard Boost Stereo. A few days ago, I hit a bump and the stereo shut off... The lights and display would still work fine, and it doesn't matter if it is on AUX, Radio, or CD.

Then I would hit another bump and it would either come back on, or the speakers would start crackling. I have also noticed that if the passenger door is slammed sometimes it would effect the output of the speakers too.

I'm pretty handy with electronics, but thought I would ask if anyone else has had this issue. It sounds like a connector is loose on the output of the amplifier section. Since it is a standard Boost model, I don't think there is an amp stowed in the back of the car, so is it possibly on the back of the stereo unit?

Thanks in advance.
