Well it can't be any worse than running your empeg through another head unit now can it Tony. Actually a small DIN sized amp *should* be better than any built-in head unit amp. I have a small 4 channel Magnat amp (Magnat Classic 170) that is just slightly smaller than a DIN slot, and I'm more than happy with it - is more than powerful enough for my factory speakers (43W/channel into 4 ohm speakers). Unfortunately you don't seem to be able to get them anymore. At least I haven't been able to find them :-(
