Also- You said you "turned the sub output off to test the door speakers." I think it should be wired like a normal speaker, it's hard to do it successfully without filters if you are using a preout, and they don't recommend any preout with fader. You may be throwing too much amp'd sub sound at it when it expects relatively normal sound that it can convert to bass. IMO you shouldn't double dip with these powered subs!
What is your per-channel output on that Pioneer? I kept stock head and amped the DB6501's with 50w to each side. Big set my amp gain to "stun but not kill" with stereo full blast, and it is plennty, even with windows down going around Willow Springs at 80-140mph with Beastie Boys (RIP MCA!)

I've tested both ways with the inversion button pressed and not.
When I say I turned off the subwoofer, I mean on my HU it has subwoofer out via RCAs. This allows you to disable the sub out so nothing goes out to the sub.
Here is the spec sheet for the HU:
AVH-P3400BH - <b>NEW!</b> - 2-DIN Multimedia DVD Receiver with 5.8" Widescreen Touch Panel Display, Built-In Bluetooth®, and HD Radio™ Tuner | Pioneer Electronics USA
So are you saying this amp/sub shouldn't be using RCA out from the back of the HU? I'm not sure why it would make a difference if it was wired as a speaker instead as opposed to RCA out. Maybe I am confusing what you are saying here..
