this is gonna be kinda long, but I need help, so bare with me. Ok I just bough an 89 4cyl notch (5.0 conversion). The radio plugs are there, but no radio. I havent even checked on the speakers yet, but Im gonna buy new ones anyway. What I want to do is get a new head unit, im leanin towards alpine or pioneer. What do you suggest for that? (on a budget, 150 tops) So ideally what Im thinkin for speakers, is 4 higher range speakers for the dash and rear speakers, and then two deeper speakers for the bottoms of the doors. I dont really know the sizes that I need, and I dont know much about what to get and what not to get. So any suggestions would be good. I'd like to buy all of this stuff on ebay If I could but I still have to see If ill even save money after shipping and all. Is it generally ok to by audio stuff off ebay? Thanks alot. btw Im gonna get a sub in time, so if this setup is not deep enough thats ok.
