I had the 8400 and went to the 147 and the alpine is much better not only does it sound better but you get the same 9band eq but you also get time alignment adjustment the Pioneer does not you can go from flat to a 24 db slop the Pioneer does not and you can also adjust independently the front rear and subwoofer crossovers and slopes the Pioneer does not the only thing the Pioneer does better than this deck is it looks a little better but other than that the Alpine gets my vote
