New deck and speakers for Integra

Im deciding to take out my old stock Acura deck and old speakers from my Integra for newer ones. The deck that I am looking at for my car is the Alpine CDA-7893. I saw in an ad that it is $299 with free install. Is that a reasonable price? What other decks do you guys recommend around that price?

Im still deciding on component speakers as well. Im looking at the Rockford Fosgate ones. Any brands and models that you can recommend that are as high as at least $129?

Last question...on a '94 Integra coupe the front speaker dimensions are 5 1/4 for the front, and 6 1/2 in the back. I heard that the FRONT can have 6 1/2. Is this true? Can it fit nicely without any cutting or anything else?

Thanks!

Help!

$299 is good for a deck & install. I got a JVC deck it was $400 plus $50 bucks install price.
