I really don't know too much about these and had to look up the information. The kenwood one that is current is the Kenwood P907. I believe(from memory) that alpine makes a very nice one of these but a phone call to their product department has yet to be returned. Even if they did, I would probably bet that the kenwood is just as good if not better. I read the specs on the P907 and they are quite impressive. And they had better be for retailing around $2200.
