Could this be a dodgy earth wire??
I posted this in the fiat forum a while back but I thought the
specialists on here might be able to help. Car:Fiat coupe 20VT "I have the standard clarion unit in the car with the CD changer, but if I turn round corners or accelerate quickly, the sound goes off on all speakers for a couple of seconds with a crackling sound thats on radio to, so it's a dodgy connection somewhere, if the problem is with the loom in the stereo, that's not too bad because I want to change it for an MP3 head unit anyway, but if the problem is further back past the iso connector, how much of a pain in the arse is it to re-wire through to all the speakers?" *Update* I have changed my head unit for an Mp3 head unit, and the fault still occurs I know now that the fault does not switch the power of the head unit off, just the sound coming from all four speakers, and it is worse when the weather is hot. For all 4 speakers to stop, leads me to think it could be something else indirectly affecting it , maybe a dodgy earth, it could be a five minute fix, but it might not be . Does the stereo wire share power with anything else with the same wire? I'm wondering if the electric windows have any relation to it, as I sometimes get the odd 'pop' through the speakers when I raise or lower either of them. Cheers Austin |

Cheers Austin It sounds like one of your speakers are shorting to ground (earth). the most common is the speaker terminals on the speaker touching the metal where they are mounted |

If it's a bad ground, it's easy to fix: attach a piece of wire to the body of the deck (if there's not already a screw for it, use the backstrap mount, or loosen one of the case screws), then connect it to a solid body ground. Don't trust that the antenna lead provides a solid ground. |

A bad ground won't just shut off the speakers but the whole radio and your
preset stations. Did you also replace the speakers in the process? I would check and make sure that there aren't any speaker terminals or even one of the speaker leads is not shorting to ground when you round a corner. How are the rear speakers mounted? Are they under a rear deck and possibly one of the terminals got ripped off the speaker and that is bouncing around and touching chassis ground. Something else to check is by taking the radio out and jiggling wires to see if something is shorting behind the radio itself. -- Pat M "Matt Ion" wrote in message news:ScZsg.155283$iF6.107163@pd7tw2no...
