Hi got a new aftermarket stereo and whilst trying to wire in the rear speakers something went bang causing the stereo to cut out and now Ive got no headlights, no radio and no ignition lights and car wont start.
I have checked all fuses even the big ones under the centre column and can't think what else could have gone bang!?!
Has anyone got any ideas please !

I'd re-check the fuses, You really have to pull each one out and look closely at them!

Long time ago i was wiring one stereo. One positive wire was badly insulated and it touched car body and it melted whole bunch of wires in couple of sec.
Could anything like this happend to You?
