I am quite the newb at this stuff. I currently have an alpine cda9833 in my car and I installed the alpine siriuis tuner. I also have my ipod hooked up through the sirius tuner. I am going to replace the speakers, add a sub and an amp. What I need to know is if anyone knows what size speakers I need. As far as I know there are 4 inch speakers in the dash, 6.5 inc in the front doors and 5.25 in the back. The thing is that I am getting conflicting info. Is this info correct? Also, does that mean that I can order any speakers that are these sizes and install them or do I have to modify anything. I want a SQ setup.
