I installed a sub/amp combo in my 2020 v6 non-bose.
The clarity of the sub was always questionable to my ears after I completed the install. Everyone else said it sounded fine, which was frustrating.
Curiosity made me drop the driver's side headliner and there was a mic. I snatched it out, and drove around like that for about 12,000 miles. Sounded fine.
Suddenly, after about the 2-3 months and 12,000 miles, I have the classic ANC woes. Sub pluses and mimicks engine noise paired with rpm. Continues with radio off, until engine off.
I was shocked it started back working after this long. My first thought is to go snatch all the mics out.
So in short... only pulling one mic, might work for a while. But not forever.
Here is some pics of my power wire feed through and connection strap made from an old stainless pot lid.
