Tweeter Whine

So I got in my truck this afternoon, and turned on my stereo. My tweeters were producing a whine/ buzz that has never been there before. I had some work done on my truck this morning, but it was suspension stuff, so I can't think why they would have touched any of my stereo wires. Any one have this issue. BTW, the truck was not cranked up, and i've had this stereo set up for about 5 months. The whine is only in the tweeters, not the 5 and 1/4, 6x9's or the subs. Any one had this before???Greed is for amateurs.

Disorder,chaos,anarchy now THAT is fun!!

The only thing I can think of is your truck has ABS or something, so the mechanic disconnected the battery or a ground cable.  You might want to check your ground connections, and just make sure something isn't loose.My ex once told me I have a perfect face for radio.

ABS? like Anti Lock Brakes, yeah i've got those, what does that have to do with it (not tryin to be a smart @$$, i'm just curious)Greed is for amateurs.

If they had to remove any brake components to get to the suspension components, sometimes they'll pull the ABS fuse or disconnect the battery.My ex once told me I have a perfect face for radio.
