Could someone confirm this diagram?
As far as I can tell, that is correct. The red/purple and black wire are spots 4 and 8 on the eight-pin connector, same one as the front door speakers. That said, I would definitely run separate power straight to the battery under the hood on an additional amp.
radioactive77- The noise cancellation shouldn't have any effect on music. The way it works is like an audio filter. It looks for very specific bands of consistent (not rhythmic) sound frequencies associated with road noise (tire hum/buzz, wind, panel vibration) and plays them back through the speakers 180 out of phase from the mics, lessening their audible impact. The Bose noise cancellation headphones work much the same way, but have an easier time, since they don't need to distinguish "inside noise" from "outside noise"... Either way, the NC
couldn't cancel out your subs entirely.
Assuming you have your gain and crossover set even close, it almost sounds like either you have your "fade" control way back, or your subs are out of phase with the rest of your speakers. In a sealed sub enclosure, out of phase subs will still move like the are "pumping", but they are really "pulling", and the air moving is just moving inside the box. If you know your positives and negatives are good from the factory amp to the sub inputs, the subs may be wired 180 from the rest. Try switching the pos and neg input wires into the sub enclosure and see if that helps.
BTW, for anyone wondering, the noise cancellation is an entirely separate animal from "speed sensitive volume", which basically just increases the output volume of your head unit as the car goes faster. It seems that the increase happens centered on, but not exactly at, the 10 incriments on the speedometer- 10, 20, 30, etc... Mine doesn't really become noticeable until about 30mph and up.
