Hissing soud is from the altenator ( not a big deal ) have a noise reducer installed or have the stereo rewired for it's power wire from a different location. Very common thing that happens by do it your selfers.

As for oil temp I'm not sure what it should be on thatcar but is it oil tem or oil pressure?

Why is there no sound through the speakers when I turn on cd/radio on 2005 corvette?


I would suspect the multi pin connector that plugs into the stereo that serves to connect to the speakers.

78 corvette, radio works but no sound, is this a antenna problem?


it could be antennae, you should hear a hiss in the speakers when you turn it up to halfway. if there is no hiss it is possible a broken connection to speakers or a blown fuse for the speakers in the car.

My 92 vette sat all last winter and I needed to replace my battery. After I replaced the battery I started the car, the stereo had a high screach sound thru the speakers, you could not hear anything...


its interference from the alternator ,for whatever reason which i think is your problem but i could be wrong it could just be the radio has damp inside it and may dry out with use like have the heater on ,without hearing the noise its difficult to pinpoint exactly what the noise is ,yes their is a difference in the type of noise as to a clue as to what is causing the noise .
