Did my head unit burn out?

[BoFadeez]

I was listening to the radio in my mustang, which is a sony head unit with 3 amps, 1 4 channel that is running my rear speakers and the other 2 for the 3 subs in the rear, and I noticed that I was having to turn up the radio louder then normal to hear the music. After about 3 days of this happening I have the volume up and I hear a pop almost like gun shot and my speakers just completly stop playing music. I went and checked the fuses in all the amps they were fine, I checked the rca cables, power cords, grounds, all fine. All amps are have power, and when I turn the radio on it shows that it is working perfect I can change the station play cds use my disc changer but no music comes out the subs work cause I can hear them power on. Do any of you audio guru's have an idea of what could be the problem? or just any ideas of things to try?

Thanks

i doubt it was the hu .. check all the speakers.. i have a ahrd time believing they would all blow at once, but i guess its possible.. i dont know crap about audio but check everything that could blow and youll be good..

sounds liek something in the signal processing of the head unit is dead... i'd get that checked out by a professional
