Recently on occasions my stereo will produce no sound. Regardless
Of being on fm/am/cd etc even in reverse the sensors produce
0 sound.
Whilst moving though I get a slight crackle through on the
Rear speakers. And the sound may even come on if I hit a good
Enough bump in the road.
The leads me to believe a loose wire could be the issue
The stereo come back on with soft startup volume.
So it appears to know that audio has been lost
I disconnected my sub aftermarket which ran through hi/lo
Converter on sub wires. Still no luck.
iPod kit appears to not affect it either.
Sometimes after I start my car it won't work even if
It worked when I last parked my car.
A nice bump may also stop audio when it's playing aswell

Has any had this issue or heard of even suggestions?

I had a similar thing happening.
Try cleaning the earth on your battery, worked for me.
