I thought the Alpine 9887 was nice, it's a little more aggressive (in your face) sounding than most decks though. The Pioneer 800prs and P99RS are more laid back sounding but I think they sound really good. The Eclipse 7100 along with Kenwoods top of the line models (I've only used one, don't remember the model number) IMO have a good mix of both and IMO sound the best. 9887 was kind of a pain to navigate with and you do have to buy everything seperately. Kenwood doesn't have full active capabilities and lack what the other higher end units have. The 7100 is a pain in the *** to navigate through. The Pioneers I've always considered the easiest to navigate through with all the active settings.
I wish Pioneer would've went a little more classier looking with this new model but atleast they wrapped in all of the features without having to purchase seperately, unlike Alpines newer units. I might get one for my g/f's car for a simple 3way active setup. Gotta finish up my system first!
