No audio from door speakers

Executive summary: Door speakers are just "woofers" (5.25" crappy OEM ones at that in a "tuned port") fed (& limited) by a crossover in an under-powered 40W amp. Now that you've replaced dash drivers to something more than the just as crappy OEM dual tweeters, your door drivers are even less effective.
You're in luck though as thousands of us went down this road well in advance of you so there are plenty of resources available to help you make wise upgrade decisions.
