1995 Sc400 Radio Making A Loud Clicking Sound

[SC400lover]

Hi folks, just joined this fantastic club and bought my first Lexus being a 1995 SC400 with 177,000 miles on her and only paid $3000. I think is a great deal but the only problem that I have with her is that when I turn on the radio it goes on for only a few seconds and then starts to make a loud clicking sound. Does anyone else have this problem and does anyone know what is causing it. And how can it be fixed. Thanks for your help.

Hi everyone. thanks again for all ur help on this but everything has been tested and it all works fine so what do u think it might be? Some one thought that it might be the telephone hookup. I have no idea. Any one have any other ideas. thanks, Marvin very happy SC400 owner

It could be blown speakers? I check/test the rear speakers before the front, the rear deteriorate due to the sun/heat exposure of the window.
