Alpine HUs FTW. I had a CDA-9827 that got stolen and it was a great HU, never let me down. As of last week I got a new Alpine CDA-9884 and it is great. Wish it had the 4V preout instead of 2V but I don't know how much of a difference it would make. But I'm not complaining, it looks good and performs great. I couldn't ask for more.
