Got a good deal on a Rockford Fosgate 4 ch amp from a member here.
I hooked it up to the door speakers (pioneers) after work last night, and WOW, what a huge dif in sound clarity. I managed to listen to a couple of good hard rock songs at about 2/3 volume and that was as loud as I wanted to take it. Sounds great at any volume now. Used to have to turn it up half way before it sounds decent, but even at low volumes it sounds clear and has nice snapping mid-range and clear highs. Woot!
Now the door speakers can keep up with the subwoofer
