I really appreciate the guidance!
- I tested the front/back controls and the bass levels - both door speakers are completely quiet
- I'm embarrassed to say that I don't know if the door speakers were ever working since my ownership. Unfortunately the CDR210 is gone, so I can't test with that radio
- The wiring appears fine and I checked the wires carefully as I added a Bluetooth module to the CD changer plug in the HU and accidentally broke a wire for that trying to slide the radio in - so visually checked the rest of the wires after that fun
- I will test the wiring from the amp to the door speakers with a 9V battery - it should make a sound if those wires are good
- I might be down to a bad HU or bad amp. I might take you up on your amp offer as that might be the easiest path - thanks!
Funny, my next project was going to be adding rear speakers to the rear storage unit but I may pause my stereo improvement activities after getting the door speakers working

Were the door speakers working before you swapped the head unit? If the speakers were working, it could be an issue with the new CDR220. To confirm that, you could reinstall the CDR210 and determine whether the door speakers are working. If you remove the head unit, look for damaged wires behind it. There is a lot of wiring packed into that area and some of it could have been damaged if it got caught between the head unit and the dashboard structure.
If you suspect a problem with the amplifier, I have a 4X40 Haes amplifier I can send you for the cost of shipping.
If you suspect a problem with the wiring, you can use a multimeter to check continuity from the amplifier to the door speakers. Unfortunately, that will require you to remove the door cards to access the wiring in the door. That will also allow you to determine whether the door speakers are defective.
I have to go to work in a few minutes, but I will search for the wiring information I found when I upgraded my door speakers when I return home tonight.
