Hi, I am a new contour buyer (just got a 2000 countor sport), and want to take out the pretty crappy deck and speakers. I am wondering what size the speakers are though. I had read the front is component 5.25" and the back is 6x8, is this correct?

Also, I have a limited budget (300-400), so if anyone has some suggestions on decent speakers and a decent deck I am all ears. No need for an amp or sub now, but I would be interested in getting it down the road (if that matters for speaker purchase now).
