Clarification indeed; you refuse to acknowledge ignorance on this matter. I've seen it with my own eyes and the signal is flat. Maybe you are referring to the non-bose system, as I've heard processing occurs in the HU whereas the Bose system occurs in the amps. Nonetheless, your whole post is littered with inaccurate information and I suggest you research and learn something on the matter. It's out there.
One thing though. I notice that on some songs (the louder ones), I think the HU will auto-volume at the top end. On quieter songs I notice a difference all the way to the top, but on louder songs, the last few volume bars don't do anything. I don't have any limiting set up in the bit one, so I'm pretty sure its actually in the HU.
^^^ this is what im talking about

Granted, I see limiting and EQ'ing differently. I agree something seems to be going on in there, but I've never noticed EQ'ing to be present. But then again, i think all the radios are different. My loaner last time I had one was non-bose, and I noticed that the volume control was much different in that it was not linear. The first few volume bars did alot, and when it got loud the sound changed. I only wish they would start doing what kia is doing, most of their new cars come with a digital, clean audio out on their stock HU's. Not used with the stock system, but if you go aftermarket your set. Lucky....

Curious. When I was toiling in my trunk splicing those small wires, I did notice that each signal pair was bundled together with a shield that wrapped both the positive and negative signal wires. This shield disappeared back into the wire bundle. I checked the continuity to the vehidle chassis and there was none. The moment I broke the shield wire loose and broke the connection, I noticed a bit of hum from the speakers and also noticed some fade and slight popping after awhile. I never thought to measure the level of the shield wire to the vehicle chassis though.
I will be taking on this adventure again in the near future as I have to reinstall my system into my new G, but this time I won't be splicing a balanced cable into the signal wires as my new Zapco DSP Z8 only takes RCAs. Hopefully i don't run into noise issues, but I know it's been done many times with good results, so we will see....

I loved my DSP 6, but hated the fact that I didn't have anyway to implement sub low end cutoff, especially since i was running IB. Aside from the fact that the Z8 did away with true balanced connections, there is more resolution in the adjustable parameters and it can handle a full 4-way setup.
