Hi guys. 2004 53 mondeo tdci head unit 6000. This is my first post so please be patient lol. My friend was trying to jump start my car the other day and put the red + wire on a bit of the engine above the alternator. (Not on the alternator directly above it at very top of the engine) Then there was smoke coming off the lead so he disconnected it. When I tried my stereo it was turned to max volume and I could only hear it if I put my head to the speakers. Would be great if some one can shed some light on it. Thanks kindly Andy :)

Sounds like you've blown the amp inside the radio.

If you could get hold of a spare to try you would know for sure.

Thanks for the reply Stoney I'll try another today if I can get hold of a one and I'll let you no.

Please do Mate.

It's the only thing I can think of which will kill the sound to all the speakers at once.

It would be highly unlikely that you would blow all speakers at once, maybe one or two possibly.

Starting with the source is always a good place to look.

keep us in the loop.
