First question: are the RCA input jacks and output binding posts insulated from the metal chassis?

[jonastus]

yes a little ring of plastic on each side

Can you check the resistance between each terminal with a multimeter? They may look fine but you never know. Since it works outside your case it's obviously a problem with the way you're wiring it inside the case.

I fix the problem It seems that the curent input was the problem now it play very well
