I need to know what the size of my speakers in my 95 3.4 camaro are? It's the 4 speaker setup. I added a pioneer drw/mp3 head unit, kenwood amp and 2 12' kenwood subs. Also, do you know what the biggest size speakers I could cram in there would be?

As far as the DVD and tv questions.. I want to get an indash(preferably) or a mounted dvd player and then add an indash screen. What other components do I need to make this work with my system? Would I no longer need to have my headunit hooked up after i get one with mp3? I really don't know much about the video stuff.. help me out. Thanks alot
