When I started the car this morning, an awful whine started coming from the speakers. It changes pitch with engine speed, so I'm assuming it's "alternator whine." I've had no other problems since I replaced the factory head unit about 7 months ago, so should I assume something just came loose? What's the first thing I should check?
I've got a 2005 Mustang with Shaker 500 stereo.
