I have stock speakers and stock head unit.. 90 gxl.. When I turn on my radio, all speakers work. Then after a short while, the left side kicks out.. I am wonder why this is? Can it be the head unit or the wiring? Also When driving agressively sometime all the sound turns off.. but the radio is still on and antenna will go up and down when you turn the radio on and off.. some time later the sound will come back.. Has this happened to anyone and what you guys do?

 

Loose connection/ bad wiring??
It sounds like after a bit something comes loose and then when sitting reseats.

 

blown speaker, or dieing head unit

 

no no no icemark, u forgot to carry your "1" , and the results on the equation = speaker ghosts

 

speaker/head unit connection are fine.. took them out and reconnected them. speakers are fine.. tested them with different system.. Looks like wiring, or head unit.. or it could be those ghosts.. aite.. thanks guys.. can you refer a good head unit?
