Question 2: If you did disconnect the ANC system, can you tell any difference in road noise, or noise from the engine as it switches from 6-4-3 cylinder operation?
Finally, please post details and photos of your system, as I am sure that many owners-like myself-are considering upgrading their sound sytems.

All head unit functions are intact nothing has changed. The ANC is intact. Basically my installer said the radio is just a head unit and it normally sends signals to an external amp where then goes to the speakers. The installer wired in the new amp where the stock was. The Alpine amp has the ability to take these signals and then send them to the speakers. The way the speakers were installed 2 sets of speakers replaced 8 speakers leaving only the small center dash speaker and subwoofer as the only stock speakers left in the car. So since the head unit is still receiving input from the ANC mics and still outputting that signal through the new amp and out to the speakers all ANC function remain intact.
My installer really knows his stuff as their team has been in upper end car stereos for literally 20 plus years. They produced award many winning competition systems in the 80's and 90's. Today they contribute many articles to Car Audio and Car Stereo Review. So these guys design and install top notch systems that play music very accurately not just maximum sound!
I can take pictures but you cannot tell it visually from the stock system. All speakers are behind the stock grilles in their stock locations.
Just a side note the speakers that came out of the Pilot are pathetic! The magnets are the size of a quarter and the cones are very flimsy. The speaker baskets are junk. these are great for keeping both weight and cost down and a majority of the people never touch them but they are first thing that needs to go!
