i have the same pioneer 3 ways as you. i have them running with about 50 watts rms each on a sony amp with a high pass crossover at right under 80 hz. the doors don't buzz like they used to (i have dynamat). and the speakers don't distort. I also have a polk dx10 running from about 325 watts rms with a low pass crossover at around 80 hz. The blend sounds really good, and i would definitally recomend crossing over the door speakers. You might want more power though. The pioneers while rated 30-21000 hz really distort with any volume at frequencies below 60 hz. i have them at 80 to reduce door panel vibration further.
