Ok, I just received my new headunit from Crutchfield, a Blaupunkt St. Louis, and it came with a free Blaupunkt 2
channel 60 watts RMS x 2 at 4 ohms (80 watts RMS x 2 at 2 ohms). Although I don't know what all that stuff means.

Would I be better off just keeping the factory amp or should I replace it with this free one I got? I'm not much of an audio buff, but I knew that the factory radio had to go. The sound is not all that great & the navigation unit pretty much sucked and I have a portable one to use anyway.
