if you go to Alpine's website (http://www.alpine-usa.com) and view the HU's you can compare them right on the site.
uhm... why not just go to their website and compare the two????
Both alpine and pioneer are good head units depending on what you want. There's a thread just a few posts down about the 9887 and 880prs.
