Question
I Just Got It As A Handmedown But After Listening To A Few CDs And FM Stations 1 Speaker Went Out, After Reconnecting It None Of The 2 Speakers Work And The System Grill On The Back Gets Hot Along With A Reving Noise When I Turn The Volume Up A Little. The Speakers Went To A Old 80 Watt Iawa Stereo And I Found A Hard Thin Wire That Was Made From Several Little Speaker Wire That I Used For The FM Antenna That Way I Could Flex The Wire As It Needed To Pick Up Signal. Did That Wire Maybe Melt And Fry The System? Just Need To Know How To Fix It If At All Possible.
Thank You And Have A Nice Day.

Answer
Don't think the antenna wire is causing any problem unless you have it touching or making connections somewhere in the set that shouldn't be.

Amp failure is most often shorts on the speaker line somewhere, shorted voice coils in the speakers (from overpowering them), dead electrolytic capacitors in the power supply and dried out heat grease on the output transistors that are causing poor heat conductivity and too high temperatures.

Maybe this will give you some ideas to follow up on.
