i used to love alpines but they lost my interest when they dropped back down to 2v preouts. I now use pioneer in all of my single din applications but i love the fact that the new Kenwood double din nav/dvd units are using Garmin navigation. just because of Garmin and the slightly cheaper price, im likely going to be getting a Kenwood and i have friends at a stereo shop that are hooking me up at cost.
