Question
I need to find information on how to repair my Alpine car stereo.  Circuitry diagrams and testing tips and procedures would be useful.  

Answer
Gabriel,
If you search around on the WWW, you may get lucky and find service info for NO charge. You also can order a service manual from Alpine, they usually cost about $15-$20. Please give me the model number of your Alpine stereo, I may have a service manual.
