I did not have to use the ANC-CH01 for my install....I have a 2020 Rubicon with the 4 cyl turbo and ANC. I used the AP4-CH41 R2 with optical out to my DSP - note that the optical output is two channel so the DSP can slice and dice it any way you wish. I am running active 3-ways plus dual subs so that takes up all 8 channels of my DSP. No issues with ANC at all, I think the AP4 removes the ANC. One added note is that I left my rear speakers connected to the factory amp. So those are still controlled by the fader when I want to add some fill with the doors off. Otherwise, I don't use the rears at all when I have doors or a top on.I'm about to upgrade my JLUR Alpine system and this is my first time doing an after market system in a vehicle. Can anyone answer the following questions for me so I can confirm how things work within the Jeep vs. someone at a shop steering me in the wrong direction.
I'm going to keep the factory head unit and use the AP4-CH41 (R.2) interface to add aftermarket DSP, AMPS, and Speakers.
1) Do I need to use the ANC-CH01 module in my setup? And what exactly do I lose or gain by removing active noise cancellation?
2) How is navigation audio / Bluetooh phones calls handled after upgrade?
i.e. Will I see a major volume difference in nav directions vs music or it coming out of all speakers vs. one side? Will Call volume have to be adjusted each time answered because music volume may be too loud, etc.
Basically, I'm trying to understand the nuances, quirks, and caveats that may be noticed by upgrading and how things act differently for the good or the bad to make sure I'm making the right decision on dumping some coin here. Thanks for the help!
I appears that my phone calls and voice commands continue to route through my front channels just like before.
