Good Day Everyone,

While driving home from work yesterday, my car's sound just died. Head unit and cd changer still powers on and works however there is no sound at all.

I have already checked the fuses in the engine bay, in the dash as well as in the boot.

I am dreading that it might be the Harman Kardon Amplifier in the boot the blew. Is there any way to diagnose the amplifier. As soon as I disconnect any radio components (breaking the fibre optic loop) the radio does power on. (Stack on Logo Screen).

Can anyone recommend any further troubleshooting options before I start replacing components? Or recommend a reliable car audio shop close to Randburg that could assist.

Thanks everyone :)
