There are pros and cons when considering which units to buy.
Here's my experiences,
I have had both brand b4, the alpine 9855 and kenwood KDC-MP828 (lower model then the anniersary but still have simlar features)
Alpine 9855
Pros:
-- MP3s files are easy and faster to search using the glidestrip,
-- Also loading Mp3 files are a snap,
-- SQ is pefect with a cleaner bass (MX Expender),
-- Sound good with either stock or aftermarket speaker
-- has two different band of EQ (5 band Parametic or 7 band graphic) for best sound shape
-- can be set as a 2-way or 3 way crossover.
-- Control up to 12 alpine amps through the HU instead of wiring
Cons:
-- GUI is too hard to operate while drive, have to go to several steps to get to what you want..for example if you want to turn on/off you sub..you have to go through menu..setup..audio..sub..then off/on.
-- Take too long for MP3 name to show up on the screen (about 5 sec),
-- Broke easy if u aren't lucky so buy a warrentty. (I bought my at BestBuy and a couple month later, it wont edject my cd and the glide strip doesn't work, lucky i bought a 4yrs services plan and went to exchange for a new one),
-- Screen are Boilite "BLACK/WHITE"..visiable at night but at direct sunlight it ****.
-- Preamp and watts outputs are lower "18RMS & 4V",
-- Not as low as i thought it would be, the loudest the volume goes to is 23 once you pass 23 it stays the same all the way to 35 max.
Kenwood Anniversary..
Pros:
-- Color and great graphic..duh
-- you can custom make your own graphic
-- HD ready for better FM reception
-- Has buit in Graphic Motion that meassure the proformance of your car.
-- Louder, SQ is also OK, You can use the 4 band Parametric EQ to adjust either front or rear speakers, while on the 9855 it aplies all speakers.
-- Higher RMS and preamp output "22RMS/channel and 5V preamp".
-- Sub control is easier to adjust and turn off/on
Cons:
-- Has only one EQ type (4 band Parametric), While the 9855 has two.."parametric and Graphic,
-- the Voice Manager the came with the HU **** and it wont read you text correctly which is very annoying. In order to search for MP3 songs..you have to use the software to burn your cds..once its burn..its only complatiable with the Kenwoord deck and it can't be play in any other different HU or cd player
-- Tend to skiped when you go over bumpy roads.."need 5 sec to resume playback, MP3 load slow.
For a quick summary..if you are into cool graphic, listen to radio, more power, then go with the kenwood. OR on the other hand..if you are an expert audio person, perfer SQ and not fantasy graphic then go with Alpine. The only problem with alpine is that if you want a very loud system you have to use a separate amp to power your interior speakers since the deck isnt that powerfull.
Thats my experiences..if you want to compare both of them..go to
crutchfield's website and read the specs of each..also there you can read the reviews from past buyer and their thoughts about each unit
As for me..iam not into either brands now..thinking of selling my 9855 and buying an eclipse CD8445
i still have the 9855 with a sirius satelite radio attena and its 5 months old and still in great shape, Like i say b4 i bought a 4 yrs service plan and its good through 2008. IF you or anyone is interested i can sell both for $350 shipped
hope this help
