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.

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.
