They cut out and make an unhappy crackling noise as the music gets through then cuts....gets through then cuts... If you turn the sound up it can push through it for a few moments... then it cuts out again. The right side is fine.
I am running the front components off a seperate Sony Amp. I know the phon cables are ok and have isolated the noise to be due to the head unit /wiring behind the dash/doors or my amp.
Any suggestions on an easy way top sort out an intermittent problem?
