I purchased my car about 4 months ago when I bought it from buddy he said his radio died 6 months before I purchased it so i looked up about the radios going in these cars and decided to put in an aftermarket Kenwood deck. I got it Installed and professionally and all wires were okay but now I have the problem when I get up in the morning and take out my car the radio is dead it lites up but has no sound until the point that my car starts giving out warm air form the heaters.
Has any one else had radio problems similar to this? Is the problem major like to the mail computer or just a simple problem?
Thanks Guys Help me Out!!

 

This sounds like a problem with the radio, not the car. Electronic circuit boards can develop cracks in the solder joints that open up when the thing is cold and close when it heats up. They can work the opposite way too. Check your radio warranty. Since you had it professionally installed, you might have a proper claim.
