Radio off when I first start my truck?

[Shaun1162]

Sorry if this question has been asked, but I can't seem to find anything to answer it...

So when I first start my truck, my radio is completely dead. No matter what you do (turn on/off, play with the volume, etc.) it won't do anything. After probably 5 minutes, it starts to come in very quiet and fuzzy, and then after another 5 or 10 minutes the radio will come in fine.

Is it something inside of the radio going bad? Or maybe the speaker (Not stock.. Got it at a junkyard)?

Thanks in advance for the help.. It's driving me nuts!
