Welcome to JustAnswer, my name is Dan and I'm here to help get your problem resolved. Does it come with a stock cd player or tap deck? Thanks
Customer: replied 5 years ago.

I just bought it used off craigslist and when I bought it, there wasnt a stereo in it (the stereo had got stolen). Since I have owned it, I purchased an OEM cadillac stereo online, i purchased 2 one with a tape deck and one that is tape and disc. But then there was the whole stereo I just want tp install an aftermarket stereo and speakers and amp but i dont want the security problem

Thanks for update, you can install a aftermarket cd player without worrying about any security related issues. Here are instructions to remove stock radio.


Then you need this install kit which will allow you to connect aftermarket stereo to this connector which will plug into stock connector so you do not need to cut any wires. And the plastic part is what cd player installs into so it fits nicely into old spot. Let me know if you have questions or if there is anything else I can do to help. Thanks.
