I'm just goin to town with these posts, but if you guys don't mind helping an automotive rookie I greatly appreciate it. Now as for the question: I would like to get a new head unit for my 1992 Sedan DeVille, preferably good quality, CD player and AUX input. If I do this: 1) what would be the best to get (yet still under $150) 2) what kind of specs should I look for to be compatible with my OEM Delco speakers? 3) am I going to have to spend a small fortune replacing my OEM speakers?? Now this is an idea I'm tossing around at the moment, I plan to use the $150 to get myself a full GM service Manual for the car first, then I'll get the head unit when I save up enough. So I'm hoping theres someone out there with experience and success in completeing this feat. I would greatly appreciate some advice. Thanks!
