Aerial lead caught behind pedal mechanism and damaged coax maybe? Can't imagine how it could be caused by an electrical fault but not an expert, could be a supply problem to an amplifier relating to common supplies?. Maybe try a cheap mag mount aerial with its own coax.

Gone but not forgotten :-)

Cheers @flashp I'll check the pedal area out as it's doing my head in as I come.to a slow down or stop and it's hissing at me  :doh: people might think I'm mad listening to a hiss  :stupid: if I can't find a solution it'll be out the window and new set up in.

Do you have fancy brake lights (eg LEDs), it's possible that LEDs or associated electronics might generate radio frequency noise.

If you're stationary and you press the brake does it still make the noise?

Or is it only when you brake hard whilst driving?

Oh noooooooo  :scared: I think it started after I fitted the inner skyline lights but can't be 100% sure as I didn't really listen to the radio then.

Yes it's the same when I'm stationery or braking and slowing down not sure about when braking hard.

Sounds like RF noise from your fancy brake lights

Maybe try and fit a shielding around the lights.  That may help.

unplug  :thinking: that'll be quite difficult as all the wiring plugs are hidden away in the boot lid.
Will need to cut the wiring at the connections behind the rear panels  :sad1:

Thanks mate

You can unplug the main two rear lights in 5 seconds. Just move the felt lining and you'll see a plug going into each unit, push a flathead screwdriver towards the front of the car and boom.

He did the skyline mod so it's no longer that simple I think...

Fuses out!
