I blew an engine fuse on my Miata and my Kenwood KDC-X859 went into the theft security mode when I reconnected it to power. After a lot of research and trial-n-error I was able to reset the code. I put the entire process and all of the useful links on my blog:

Kenwood. Sony is garbage.
To reset a Kenwood stereo after replacing the car battery, first, turn on the ignition and power on the stereo. If it does not automatically reset, locate the reset button, usually found on the front panel or behind the faceplate, and press it with a small tool like a paperclip. This will restore the factory settings, allowing you to reconfigure your preferences, such as the time and radio presets. Finally, check the user manual for any model-specific reset instructions.

Press the reset button on your car CD player. For example my kenwood would have the reset button located on the facia front.
To reset your JVC car stereo, locate the reset button, which is usually a small pinhole on the front panel. Use a paperclip or a similar object to press and hold the button for a few seconds. If your model doesn't have a reset button, you can also try disconnecting the car battery for a few minutes to reset the stereo. After the reset, you may need to reprogram your settings and presets.
For the best rated brands of car stereo speakers, Kenwood, Sony, Infinity, and Rockford Fosgate are among the highest rated. The prices are also reasonable.
