Why would anybody want to spend that much money on the Alpine F1 status unit. It is so expensive, it is rediculous!! 4000 usd for a head unit and processor/ multimedia unit. Alpine is FOS!! The Alpine units I have had I have not been very impressed with, and other brands offer better equipment for less money. Alpine does though have the best monitors clarity wise though, but their head units are overpriced and unreliable. I have had a CDA-7893, CDA-9811, and CDA-9831 and was not very impressed by any of these units. One feature I do like on the CDA-9831 is that you can control your V12 amps from it, which used to be a seperate, 100 usd display.
