Radio pops and hisses when going over bumps - bad connection ?
A new one for you.
When I go over bumps and potholes on our wonderful roads, my stereo pops and hisses.
It does this no matter if it is turned off or on.
In fact sometimes, I can hear a faint hiss coming from the speakers constantly, until I turn the engine off.
Even more, I think I have heard the hiss change pitch to match the revs of the engine.
What is up with that ?
I have taken the radio out, reseated all the plugs, done the same for the subwoofer, but no effect. I cannot find any further connections behind the dash to mess about with.
Could I have a loose ground somewhere ?
